    I have a CSV that holds between 1,000 and 10,000 phone numbers and I need the matching Telegram usernames for each one. Along with the username, please also capture the visible profile name; no other profile details are required. The workflow I picture is straightforward: you read the CSV, query Telegram through an API-friendly library such as Telethon or Pyrogram, respect any rate limits or privacy constraints, and return a clean file (CSV or XLSX) with three columns: phone number, username, and profile name. A brief read-me that explains how to run the script and obtain the same output on my side will complete the hand-off. Accuracy matters more than speed, so build in proper error handling and logging so I can track numbers that could not be matched.

    Hello, I am looking for an experienced developer who can understand, maintain, improve, and further develop my existing project. What is My Project? My Project is a file hosting and sharing platform where users can upload files and generate shareable links. The main concept is similar to a cloud-based file hosting service. Users should be able to upload files, store them on the server, and share them with others using generated links. The platform already has an existing system and infrastructure, so I am looking for a developer who can first understand the current project properly and then continue its development. Main Features / Functionality Some important functionality of the platform includes: File uploading File storage and management Shareable download links Link conversion / gener...

    Unlimited US-Canada SMS Server

    ยืนยันแล้ว

    I’m putting together a dedicated bulk-SMS server that lets me reach any U.S. or Canadian mobile number—no daily caps, throughput throttles, or carrier-imposed ceilings. The platform must handle both promotional and transactional traffic reliably, and keep my sender reputation intact while doing so. Core functionality I need on day one: • Delivery reports that show real-time status per message, including carrier feedback when available. • A built-in scheduler so I can queue campaigns hours or days ahead without leaving the dashboard open. • An intuitive contact-management area where I can import, segment, tag, and scrub lists before pushing Send. I expect a web dashboard (responsive is fine) plus API access or SMPP connectivity for automated pushes from my...

    BEDS24 OTA Integration Setup

    I already run my properties through an active BEDS24 account and now need the channel connections finalised so everything stays perfectly in sync. The integrations I am after are Airbnb, Expedia and, if possible within the same workflow, Vrbo and Trip.com. Key objectives are straightforward: every calendar must mirror BEDS24 in real-time, my dynamic prices need to flow out automatically, and new reservations (or changes and cancellations) must drop straight back into BEDS24 without manual touch-ups. For each channel I expect: • Two-way availability and rate sync verified with a live test booking • Reservation, modification and cancellation mapping confirmed inside BEDS24 • Clear documentation or a short screen-share walkthrough so I can troubleshoot or add future l...

    My WhatsApp Cloud API was suddenly disabled without any clear explanation from Meta. The only recent change on my side was an integration with new software, so I need someone who understands the Meta Business Manager console, WhatsApp Cloud API policies, and the usual compliance pitfalls to: • Diagnose the precise reason behind the suspension (working directly in Meta’s developer dashboard or via support tickets if necessary). • Restore full API access so message sending and template approval function normally again. • Review my current integration, webhook setup, and message flows, then pinpoint what likely triggered the block. • Provide a concise action plan and best-practice checklist to keep the account compliant going forward, including template guid...

    I need a lightweight Python script that can automatically collect user-profile information from public social-media posts. My immediate goal is to feed a list of post URLs or user handles into the script and receive a clean, structured dataset (CSV or JSON) that contains the core profile fields—username, display name, bio, follower/following counts, and any other non-private details that are easily exposed on the page. I haven’t locked myself to a single platform, so feel free to design the solution around the APIs or HTML structures of Twitter, Facebook, Instagram, or a combination that you think will hold up over time. If official endpoints are rate-limited or incomplete, please outline any headless-browser or request-based fallback you plan to use, along with how you will s...

    I’m looking for a reliable Shopify, META & Google specialist to take full ownership of the store’s monthly upkeep.

    My mobile application needs a working Meta Business Verification API key so it can start calling the Facebook / Instagram Graph endpoints without sandbox limits. I already have a Meta developer account and a verified business manager, but I have not been able to generate the production-ready key that unlocks the required scopes for a mobile environment. I need someone who knows the exact sequence inside Meta’s Developer Dashboard—creating the app, submitting for App Review, configuring Data Use Checkup, and finally retrieving the long-lived access token or app-secret–proof that works inside a mobile build. Whether the app is shipping on iOS, Android, or both, the goal remains the same: deliver a key that passes Meta’s validation screens and can be dropped straight ...

    EZCap Automated Medical Claims Adjudicator

    Do not bid if you don’t have proven experience with EzCap software. I need a developer who can turn my EzCap concept into a working engine that receives medical claims and adjudicates them end-to-end. The focus is squarely on claims processing: once an 837-P or 837-I file (or an API payload with the same data) lands in the system, the application should parse it, run every prescribed validation rule automatically, and return a clear pass/fail status for each service line. Key Requirements: • Practical experience with EzCap software. Please provide examples of reports or automations you've implemented specifically within this platform. • Automated validation checks – CPT/ICD compatibility, duplicate detection, member plan match, and any other edits we load into ...

    I recently inherited a web + mobile platform that lives in GitHub and is deployed through Vercel with Cloudflare in front. Everything runs, but the architecture feels overly complex and the camera/gallery upload feature fails intermittently. Before we add new features, I need a clear, lean foundation. Here’s what I need from you during this short, fixed-price engagement: • Map the current setup end-to-end—repos, environments, connected services, databases, file storage, and the release paths for iOS/TestFlight and Android. • Trace and document the intermittent upload failure so I know exactly where it breaks and why. • Pinpoint any duplicated or undocumented pieces in the backend services and API integrations, then recommend removals or refactors. • ...
