I need a reliable developer to turn my idea into a functional Android application. At this stage I only require a simple, well-structured MVP that can later scale as new features are defined. Key needs: • Build a clean codebase for Android (latest SDK, Kotlin or Java—whichever you prefer). • Implement a straightforward UI with basic navigation and placeholder screens; final visuals can wait until the next phase. • Set up fundamental app architecture (MVVM or similar), user input forms, and local data storage so I can see real interaction on a device. • Provide clear instructions for running the project in Android Studio and generating an APK. I have not locked the app’s exact purpose yet, so I’m looking for someone who can advise on best...
I need the TikTok SDK added to both the Android and iOS versions of my mobile app so I can pull accurate in-app analytics from TikTok’s dashboard. The focus is strictly on analytics events (no login or video-sharing features). Alongside the SDK setup, I also want Appsflyer integrated and configured so the attribution data and TikTok event data line up for clear cohort reporting. Both projects already compile and ship; you will be dropping in the SDKs, wiring the events, and confirming everything reports correctly in the respective dashboards. Key deliverables: • Add the latest TikTok analytics SDK to the existing Android (Kotlin/Gradle) and iOS (Swift/Objective-C with CocoaPods) codebases. • Map and fire the agreed-upon event list (installs, opens, ...
...recalculate if the driver leaves the suggested path. I already handle trip creation, fare logic and user authentication; what’s missing is the seamless mapping layer that ties it all together. Key points you’ll tackle • Native navigation routes surfaced for drivers and mirrored (read-only) for passengers • Smooth hand-off from my current pickup / drop-off coordinates into Google Maps SDK or Mapbox Navigation SDK without forcing users into an external app • Support for future options like shortest route, toll avoidance or multi-stop legs, so design with extensibility in mind • Clear, well-documented code plus any required API keys or configuration notes so I can replicate the setup in staging and production Acceptance criteria 1.

...the buyer clicks my PayPal payment button, they must be taken smoothly through checkout and, once the transaction is approved, automatically receive 10 invoices. The pages are being coded in Visual Studio Code, so please supply clean, well-commented code snippets or modules that drop straight into that environment. I do not mind whether you handle the PayPal interaction with their JavaScript SDK, REST API, or a lightweight serverless function—use whichever approach gets a fast, reliable redirect and confirms payment instantly. What matters is that the moment PayPal sends back its success response the customer is served those 10 invoices (PDF is fine) without extra clicks or waiting. If you prefer to generate them on the fly, great; if you want to host pre-rendered fil...
We are hiring one senior Unity XR developer to build and ship a commercial standalone Meta Quest 3 / Quest 3S title for the Meta Horizon Store. This is a fixed-price, time-critical project with two connected deliverables: 1. a polished commercial Quest title 2. the reusable engine foundation it runs on, designed to support ...to these questions: * How do you install and version-pin Meta XR packages for Unity 6 LTS in 2026? * What is your Addressables handle-release discipline? * Why avoid direct OVRCameraRig in new projects? * Why is unreliable for subtitle sync on Quest? * Share one Horizon Store title you personally shipped. * What is your process for evaluating mid-project SDK updates? NDA, IP assignment, and milestone-based payment are required.
...the basics are in place. Technical notes Please choose the framework you are most productive with—native Swift/Kotlin, Flutter, React Native, or another cross-platform SDK are all acceptable as long as the UI looks consistent and the codebase can be maintained. H.264/H.265 decoding, RTSP/ONVIF compatibility, and HTTPS authentication will likely come into play, so experience with video streaming libraries (FFmpeg, WebRTC, or similar) is important. Deliverables 1. Source code with build instructions for both platforms 2. Signed builds ready for TestFlight and Google Play internal testing 3. Brief user guide and API/SDK documentation for future maintenance Acceptance criteria • Live video starts within two seconds on a standard Wi-Fi connection • Pl...
...The scope is focused on invoices and payments only, and the data must move in both directions so whichever system is updated first becomes the source of truth. An overnight (once-per-day) schedule is sufficient as long as it can be triggered manually when required. Sage 100 is installed on a Windows server inside our network; Zoho Creator is, of course, cloud-based. You may leverage the Sage 100 SDK, Web Services, ODBC, or a lightweight middleware layer—whatever delivers a secure, authenticated connection without leaving data exposed. Likewise, Deluge scripts, Zoho Creator APIs, or a small Node/Python service are all acceptable on the Zoho side as long as the final solution is maintainable by our internal IT team. Key points I care about: • Accurate bi-directional sy...
...streamlined flow. When the user opens the page, a report (already generated as PDF) must appear directly inside the page through an embedded viewer—no pop-ups, no forced downloads. After reviewing the document the user will place a handwritten signature on a Wacom device. I am not tying this to DocuSign, Adobe Sign, or HelloSign; the signature should be captured straight from the Wacom tablet using its SDK or another reliable method your propose, then burned into the PDF. Once signed, the same page should immediately save the updated PDF back into EBS as an attachment (BLOB) so it is viewable from the standard Attachments form. The file format remains PDF from start to finish. Deliverables • Fully deployable OAF page (PG & RN files) with embedded PDF viewer ...

I have an existing Flutter code-base that already compiles for Android; the only missing piece is a working connection to a Phantom Solana wallet. All UI elements are in place, so your focus is strictly on wiring the wallet flow: deep-link or in-app browser hand-off, secure key handling, ... Acceptance criteria: • On a real Android device, tapping “Connect Wallet” launches Phantom, allows approval, and returns to the app with the user’s address. • Subsequent taps recognise an already-connected wallet and pull the current balance via web3. • Code is organised, commented, and builds with flutter build apk without extra steps. If you are comfortable with Flutter, Dart, Phantom SDK, deep linking and Solana RPC endpoints, this should be a quick win...

Each scene loads in under 3 seconds and maintains 72 FPS. 2. Coping modules can be invoked, skipped, or repeated without breaking immersion. 3. Event logs con...
...READ_MEDIA_IMAGES / READ_MEDIA_VIDEO permissions and still show an outdated name on both stores. I need those permissions completely removed or disabled on Android, the new name applied consistently across both platforms, and fresh release builds generated. The work involves: • Updating Android manifest (and any Gradle-side declarations) so no media-scanning permissions are requested when targeting the current SDK level. • Renaming the app everywhere it appears—bundle identifier where necessary, display name, launcher label, and any store-visible strings—on both Xcode and Android Studio projects. • Producing new signed deliverables: an AAB ready for Google Play and an IPA (or Xcode archive) ready for TestFlight/App Store Connect. Acceptance crit...
...production-ready tool. Key Responsibilities: 1. Develop a Serverless API: Design, build, and deploy a robust and scalable serverless API on Google Cloud Platform (GCP), using either Google Cloud Functions or Google Cloud Run. 2. Integrate with Google Earth Engine (GEE): This is the core task. The API you build will receive requests from our frontend and use the Google Earth Engine API (preferably the Python SDK) to perform on-the-fly analysis. 3. Process Imagery Data: The initial API endpoint must be able to: o Accept parameters from the frontend, including an Area of Interest (as a GeoJSON), a date range, and the type of analysis required (e.g., 'NDVI'). o Use these parameters to query the GEE catalog (e.g., Sentinel-2 or Landsat collections). o Perform raster calculat...

...straight into Google Ads. I need someone to integrate the latest Firebase SDK, configure the project on the Firebase console, and then log two core events—User sign-ups and In-app purchases—so they appear as conversions in Google Ads for campaign optimisation. Once the SDK is in place, I’d like the events tested end-to-end: from a real action inside TestFlight or a simulator, through the Firebase DebugView, all the way to the Google Ads dashboard. Please also verify attribution windows and the correct use of GAID/IDFA so reporting lines up with Apple’s privacy requirements. If you see quick wins for future expansion (for example adding Level completions later), flag those in your notes. Deliverables • Firebase SDK added to the Xcode ...
I need an experienced Android developer to turn my concept into a polished, production-ready app built natively for the latest Android SDK. I’ll provide the overall functionality goals during kickoff, but the visual direction must come entirely from a custom design created from scratch—no templates or off-the-shelf themes. Your process should cover UX wireframes, high-fidelity UI mock-ups, and the full Kotlin/Java codebase, all aligned with current Material Design guidelines while still feeling unique. Smooth performance, clean architecture, and well-commented code are essential because I plan to scale and maintain the app long-term. Deliverables: • Interactive Figma (or similar) design files • Compilable Android Studio project with source code • Si...
...an on-device database such as Core Data or SQLite is fine; no remote sync is required at this stage. Swift/SwiftUI or UIKit with AVFoundation (for live scanning) and PDFKit (to render the filled liability form) fit the job, but I’m open to your preferred Apple-approved libraries if they meet the same goals. Please include a detailed project proposal covering: • Your chosen barcode/QR scanning SDK if you will not rely solely on AVFoundation. • How you will generate and store the liability form (PDF template, print/share options). • Milestone breakdown from prototype to TestFlight build. • Any assumptions or small UI mockups that illustrate your minimal design approach. Acceptance criteria – Universal binary runs on iOS 16+ iPhone and iPa...

I’m preparing for three AWS-issued RDS Planned Lifecycle events and one SDK deprecation. All of our databases sit on AWS-managed RDS (answer recorded as “AWS”), and the immediate job is to upgrade each existing instance to the newest, fully-supported engine version rather than migrate to fresh instances. Your task is to plan and execute those in-place upgrades, validate performance and compliance, and then update the application build process so it uses the latest AWS SDK before our next production publish. Work will include snapshotting for rollback safety, applying the upgrade in a controlled window, and confirming that connectivity, IAM roles and monitoring continue to operate as expected. Deliverables • Successful, documented upgrade of the ...

I want to launch a dedicated Android social media app and need it developed from the ground up. The platform is Android only, so please focus on the latest Android SDK while keeping compatibility back to at least Android 8. I already have wireframes that outline a familiar social feed: users create profiles, follow one another, post photos or short videos, like, comment, and receive push notifications. Your role is to refine the UI to Material Design standards, build the front-end in Kotlin or Java, and connect everything to a scalable cloud back-end—Firebase is my first thought, but I’m open to an alternative you can justify. Robust authentication, real-time data sync, and basic content moderation hooks are essential. Performance, security, and clean, well-commented co...

I need a seasoned iOS engineer to wire full Stripe support into my Swift-based app. Your task covers both sides of the fence: • In the app: build clean, production-ready flows for payment processing and payouts using Stripe’s latest iOS SDK. The UI is already in place; hooks for card entry, Apple Pay and instant payout status simply need reliable Stripe logic behind them. • On the server: stand up a small, well-structured Node.js backend (Express is fine) that handles customer creation, payment intents, webhook handling, and payout scheduling. The mobile client should talk to it through lightweight, documented endpoints and all secrets must remain server-side. I’m interested in developers who have shipped several Stripe-to-iOS integrations before and can poi...
I’m moving an existing Unity project up to the latest LTS release and the console is now lighting up with compilation errors tied to an outdated SDK. The culprit is a “fragment” SDK that our user-interface elements rely on; anything that touches those UI fragments refuses to compile. Here’s what I need from you: get the project running in the newest Unity version, bring that fragment SDK (and any other hidden dependencies) up to date, and hand the game back completely error-free. Deliverables • Project opened in the current Unity LTS with zero compilation errors • Updated or replaced fragment SDK plus any secondary outdated packages • Clean builds: Android (AAB/APK) and iOS (IPA or Xcode workspace) Acceptance cri...

The finished work should include: – Source code in a Git repository – An installable APK for testing – Step-by-step build and deployment instructions If third-party libraries are used for the cart or payments, they must be well-documented and licensed for commercial use. I will provide brand assets and any gateway c...
I have the complete source code for a mobile app and now need it published on both Google Play and the Apple App Store. The build, signing, and submission steps for APK/AAB and IPA are where I need you to jump in. Because I’m not certain which minimum Android SDK level or iOS deployment target is safest right now, I’ll rely on your recommendation there. Please suggest sensible, up-to-date version thresholds that will maximise device coverage without risking rejection. On the store-front side I’ll prepare most of the wording and graphics, but I do want partial help: a quick review of my descriptions, guidance on required screenshot sizes, and a check that the listing metadata meets each store’s rules. Deliverables • Compiled, signed, and successfully...
I have a finished mobile game ready to reach players and I’d like an experienced hand to make sure everything is done correctly. . The goal is to get my game approved and visible in the store. That involves: • Verifying the APK/AAB, signing key, version codes, and target SDK so they meet Google’s latest requirements. • Uploading the store-listing assets I provide (icon, screenshots, feature graphic) or letting me know precisely what is missing. • Completing every Play Console form—content rating, privacy policy, target-audience declaration, pricing and distribution territories, testing tracks if needed. • Submitting the build and staying on board until Google flags the release as published with no policy warnings. The job is done when ...

I need a compact script (Python is fine, but I am open to Node or any language the broker SDK supports) that can talk simultaneously to Kotak Neo, Fyers, and Dhan REST/WebSocket APIs. The workflow is straightforward: • On my signal I will pass a symbol, entry price and total quantity. The program must split that quantity 25 %, 25 %, 50 % and fire three separate limit orders (target 1, target 2, target 3). • A fixed 2-point stop-loss order has to be attached immediately; if the broker supports OCO/bracket use it, otherwise emulate it through the API. • As soon as either the stop or the final target is hit, the logic should place a fresh re-entry order at the original entry price, repeating the same 25/25/50 allocation. This loop continues until I manuall...
