Security is critical—patient data, schedules, and notifications must be handled through well-structured, GDPR-aware code and modern Android best practices. Deliverables • Production-ready APK (and source) built in Kotlin or Java • Clean, scalable architecture with clear comments • UI/UX assets and hand-off files (Figma, XD, or similar) • Guidance through a basic Google Play deployment so we ...

...strangers at the tap of a button, exactly the way Connecto does. The core experiences I need working smoothly are: • Random voice calling • Random video calling (switchable during a session) • In-call and lobby text chat A clean, minimalist interface is important: one main “Start” button, instant pairing, and a small toolbar for mute, camera flip, end call, and report/block. I’m open to Kotlin or Java on the client side, and WebRTC (or any proven low-latency alternative) for the media layer. If you prefer Firebase, Node, or another stack for signalling and session control, just outline how you’ll keep it stable under load and how moderation/reporting will be handled. Deliverables 1. Complete Android Studio project with documented so...

...extended with gameplay features that set it apart. The essentials I have in mind are: • Mini-games – fast-paced sessions that players can jump into from a central menu • Custom plugins – original code, not just public downloads, to handle unique mechanics and economy hooks • Hub lobby – a polished spawn area that routes players smoothly to every game mode That means writing or adapting plugins (Java/Spigot, Paper, or another framework you recommend), configuring permissions, worlds and databases, and stress-testing the setup so it performs well with a healthy player load. Deliverables 1. Fully configured Minecraft game server, ready for deployment and improvements with the option to configure everything. 2. Source code for every custom p...

My React front-end talks to a Spring Boot (Java) back-end that lives on a VPS. The feature set is ready, yet three areas keep breaking: database interactions, several API endpoints, and the authentication flow. I have already combed through the server logs for stack traces, but the root causes are still hiding. I need someone who can jump into the existing repository, reproduce the problems locally or directly on the VPS, and deliver clean, well-documented fixes. You may rely on any familiar tools—IntelliJ, Maven, Postman, Docker, TestContainers—as long as the final result is a stable build with all tests passing and no regressions on the React side. Deliverables • Updated Spring Boot codebase with functioning database, API and auth logic • Concise change l...

I am ready to dive into natural language processing and would like structured, hands-on coaching that takes me from the basics to building reliable text-classification models. My preferred language is Python, so examples should rely on common stacks such as Jupyter Notebook, Pandas, scikit-learn or, when it makes sense, PyTorch and Hugging Face Transformers. Java and R are not in scope for this engagement. Here is what I need from you: • A clear learning roadmap that starts with data cleaning and exploratory analysis, then walks through feature engineering (tokenisation, embeddings, etc.), model selection, training, evaluation and deployment. • Well-commented Python notebooks and sample datasets so I can reproduce every step on my own machine. • Short explan...

...a very simple interface with only the essential buttons needed to start and stop mirroring or read texts. Icons, colours, and layouts can stay basic—function over form. Technical freedom is yours, yet I expect smooth frame-rates for the mirroring (WebRTC, RTSP, or any efficient protocol you prefer) and reliable, near-instant SMS capture using Android’s default permissions model. You may work in Java or Kotlin inside Android Studio; just make sure the final APK installs cleanly on Android 8.0 and above. Deliverables 1. Signed, install-ready APK. 2. Complete, well-commented source code. 3. Quick setup guide so I can rebuild the project myself. When I open the app on both phones, I should be able to pair them (QR code, IP entry, or any one-step method) and imm...

I’m expanding a vetted network that places senior-level developers in long-term, high-paying roles with top-tier U.S. companies operating on CST, EST, and PST schedules. To join, you’ll need 4-6 years of solid professional experience building production systems in Java, C#, or Python, plus enough front-end know-how to collaborate comfortably with React, Angular, or Vue teams. Excellent spoken and written English (C1 or above) is essential because you’ll attend client-facing interviews and daily stand-ups. If you thrive in remote environments, can overlap at least four business hours with U.S. time zones, and enjoy tackling complex backend or full-stack challenges, let’s talk. What happens next once you apply: • A short screening call to confirm techn...

I’m ready to launch a dedicated Android e-commerce application that will showcase and sell physical products only. The goal is a smooth, secure shopping experience from browsing to checkout, built natively (Kotlin/Java) or with a reliable framework such as Flutter—whichever you’re most comfortable with for optimal Android performance. Core flow I have in mind: a clean product catalogue, searchable categories, detailed item pages, a persistent cart, integrated payment gateway, and basic order-tracking for customers. I will provide product data and branding assets; I need you to turn them into a polished APK, connected to a lightweight admin dashboard or API of your choice so I can manage inventory and fulfil orders without touching code. Please keep the initial re...

I have an existing Task Management System built with Java, MySQL, HTML, CSS and JavaScript. It already handles user registration, task creation, updates and progress tracking, but I now need a round of polishing and growth. Improvements I want right away involve • giving the interface a cleaner, more responsive look and feel, • tightening performance so pages load quickly even with a large task list, and • hardening security around authentication, role-based access and data storage. On top of that, I’d like to expand the product with new functionality—think calendar-style views, smart notifications or whatever you propose—and connect it with popular collaboration tools (for example Slack, Microsoft Teams or Google services). If you have ideas...

...can take it from concept to a polished launch-ready build. The first milestone is rock-solid user authentication—secure sign-up, log-in, and password recovery—with clean error handling and a future-proof structure that makes it easy to extend into features such as push notifications or in-app purchases later on. You’ll handle the entire Android stack: UI that follows Material Design, Kotlin or Java (your preference, as long as code is well-structured and documented), interaction with a back-end auth service (Firebase Auth works, but I’m open to your suggestion), and creating a signed release APK plus source in a Git repository. Once I can install the APK, create an account, sign in, and sign out without issues, we’ll wrap the sprint. Clear, comme...

I will consider the project complete once I can: 1. Install the APK on a physical device without errors. 2. Start a live class, have a second device join, and see video plus two-way chat working. 3. Create a sample assignment and verify that a student account can submit work and that I can vie...

I’m ready to move my manual web-app tests into a dependable Java + Selenium framework. The suite must cover the current regression scenarios of my application and run reliably on Chrome (other browsers may follow later, but Chrome is the immediate need). Here’s what I’m expecting from you: • A clean Maven/Gradle-based project written in Java, using Selenium WebDriver and a test runner such as TestNG or JUnit • Page Object Model (or an equally maintainable pattern) so future tests are quick to add • Parameterisation for environment URLs and credentials, pulled from a config file or environment variables • Clear, human-readable reports (Allure, Extent or similar) generated automatically after each run • Command-line hooks so ...

I need a seasoned full-stack developer who can step in as my technical interviewee for incoming projects. The conversations will be held in English at a solid B2–C1 level, so you must feel comfortable leading nuanced, in-depth discussions. The interviews revolve around full-stack development. Most applicants claim experience with JavaScript/React, Python/Django, and Java/Spring, and many also list C#. I expect you to move effortlessly among these stacks, probing their real-world knowledge of architecture, coding standards, debugging, testing, and deployment. Feel free to shift the conversation when a candidate mentions additional technologies, yet keep the core assessment anchored in those four primary stacks. Here’s how we’ll work together: • Before each se...
