I’m extending my Bedwars1058 server into a truly competitive arena and need a ranked system coded right away. The core requirements are already mapped out—placement matches, ongoing MMR updates, a /rank lookup, and full data persistence—but the make-or-break piece is fair, dynamic matchmaking. Players must be grouped with opponents of similar rating, with the queue smart enough to widen its tolerance only when wait times get excessive. Everything has to slip neatly into the existing Bedwars1058 ecosystem; no changes to the core game, no clunky commands. Java, Spigot/Paper APIs, and solid MySQL (or equivalent) handling will all be in play. The finished module should: • Track first-ten placement games, establish an initial MMR, then adjust after every win, loss, kill...

I need a secure, lightweight VPN application built for both and Android. The interface can stay minimal; stability, speed, and protocol flexibility are the real priorities. Core capabilities I expect: • Kill switch that reliably blocks traffic if the tunnel drops • Split tunneling so the user can choose which apps bypass the VPN • Support for the following protocols or transport layers: ssh, ssl, udp, v2ray, and websocket • A menu of multiple server locations that I can expand later through simple JSON or similar remote config No in-app user-authentication flow is required; the build should assume pre-provisioned profiles or embedded credentials.

I need a native Android application that lets my field marketing executives capture every customer inquiry, flag a lead as converted, update the sale’s current status, and instantly see how they are performing throughout the day—even when the signal drops out. The whole experience must feel light, launch quickly on modest devices, and never stall in a poor-network area. All records should be written to local storage first and then pushed to our server automatically through periodic background sync. If the phone is offline the user can keep working uninterrupted; once coverage returns the queued data syncs silently in the background. A compact on-device dashboard will summarise each executive’s day: total inquiries, conversions, sales status changes, and any other KPIs w...

My Java-based desktop application currently throws errors whenever a user tries to import an Excel file, and the files it exports need a small formatting tweak before they are usable. The rest of the program works well, so I’m looking for someone who can go straight to the file-handling layer, diagnose the functional bugs, and leave the UI and business logic untouched. Here’s what I need from you: • Identify and resolve the exception that appears during Excel import (the stack trace will be provided). • Adjust the export file so that matches the format required (change date in american format to eu format). • Keep the fixes confined to the existing codebase—no major rewrites—while following the project’s current build process (Maven, Java...

I need a reliable solution that can pull data from LinkedIn and insert it straight into a database I specify. The core requirement is the automated transfer—once the tool finishes scraping, every captured field should already be sitting in the database ready for queries and reporting, no manual copy-paste. You’ll advise me on the best approach to authenticate, respect rate limits, and minimise the risk of blocks while still collecting the typical profile-level details (name, headline, company, location, experience, education, skills and anything else you can legally obtain). I will confirm the final field list before you begin. Key objectives • Build or configure a scraper / API wrapper that logs in, navigates to each target profile and captures the agreed-upon fields ...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus.

I’m building a small showcase app for a school contest and need a polished Android solution that makes printed text friendlier for students with dyslexia. The flow is straightforward: the user opens the camera, points it at a page, and the app instantly recognises the words (OCR). As soon as the text is captured, each word is spoken aloud in sequence while that same word is highlighted on-screen in real time. The result should feel like a karaoke-style guide that lets the reader follow along word by word without losing their place. Must-have fundamentals • Android only — Kotlin or Java is fine, as long as it runs smoothly on common mid-range phones. • Real-time OCR (Google ML Kit, Tesseract, or any on-device library you prefer) with no dependency on an active int...

I need an end-to-end web application written in pure Go, backed by a MySQL database. The core focus is clean, idiomatic code that can be compiled and deployed on a standard Linux server without fuss. You’re free to structure the project with popular Go web frameworks such as Gin, Echo, or Fiber, as long as the final build remains lightweight and easy to maintain. I will supply server access and a blank MySQL instance; you take it from there—designing the schema, wiring up the handlers, and exposing routes that follow REST principles. Code quality, straightforward error handling, and secure interaction with the database are priorities. If you prefer containerisation, feel welcome to include a Dockerfile so the whole stack can spin up locally with a single command. Deliverables...

I need a straightforward Android application that lets my customers send money to me by bank transfer. After signing up or logging in with the classic username-and-password flow, a user should be able to choose an amount, see (or pre-fill) my banking details, and push the payment through an integrated bank-transfer API. Security is critical, so the credential flow must be encrypted end-to-end and the transfer requests signed or otherwise verified to prevent tampering. A lightweight backend—REST or Firebase Cloud Functions is fine—can manage authentication, session tokens, and payment-status webhooks. Please deliver: • Full Android Studio project (Java or Kotlin) • Secure username/password authentication flow • Bank-transfer API integration with success/...

I’m building a B2B platform that now has to expose a well-structured REST API so other services can hook in without friction. The immediate priority is to wire my software to a range of external providers—including SMS / Voice APIs, social-media feeds, data-enrichment sources, single-sign-on, scheduling tools and some AI/ML services—while keeping the interface consistent for our own clients. Here is how I picture the job: • Design clean, versioned REST endpoints that sit on top of our existing stack (Node + Postgres) and follow standard verbs and status codes. • Build the integration layer for each third-party service. I need graceful handling of auth flows (OAuth2, JWT, API keys), rate-limits and retries, plus a simple way to toggle providers on or off. &bu...
