I’m migrating an older Java backend—built on legacy Spring and Hibernate—into a fresh Spring Boot 3 project so the stack is fully modern and future-proof. The focus is code refactoring: untangling dated patterns, replacing XML configuration with annotations, adopting Spring Data JPA, and cleaning up any deprecated API usage. No new features are needed right now; the goal is pure code modernization. You’ll receive a private Git repo containing the current application and a lightweight skeleton for the new one. Work incrementally, push frequent commits, and raise pull requests so the migration stays transparent and reviewable. GitHub Actions is already wired, so every PR should keep the build green. Deliverables • A runnable Spring Boot 3.x application t...

...and remain visible indefinitely. • Any clip that is not pinned must be automatically removed exactly one hour after it is created (or last edited), even if the app is closed in the meantime. • Visual feedback is important: pinned items should be clearly distinguishable from regular ones (icon, color badge—your call, as long as it follows Material guidelines). You are free to work in Kotlin or Java and may choose the persistence layer that best fits—Room, DataStore, or another solution—so long as the auto-deletion runs reliably in the background (WorkManager or an equivalent scheduler). Deliverables: 1. Updated project files implementing the pin logic, time-based cleanup, and UI cues. 2. A brief README explaining where the core code lives an...

...implement core gameplay mechanics, UI, and animations • Optimise performance across the current Android OS range • Integrate ads, in-app purchases, leaderboards, and basic analytics • Produce a signed, release-ready APK with complete, well-commented source code Preferred toolset Unity with C# would be ideal because my early prototypes live there, but I’m open to a native Android Studio (Java/Kotlin) approach if you can justify the benefits. Acceptance criteria • Smooth, crash-free gameplay on mid-range devices at 60 fps • UI scales correctly from 5″ to 10″ screens • Google Play pre-launch report shows zero critical issues The focus for now is Android only; if things go well, I may consider an iOS port later. When yo...

Our engineering organization is doubling down on shift-left quality, and the next milestone is a fully automated test suite that lives alongside the codebase and runs on every commit. The work spans strategy, hands-on coding, and mentorship. You will craft an automation framework in Selenium, writing suites in Python, Java, and JavaScript—whichever language best fits each micro-service. Functional coverage comes first, followed quickly by performance scenarios that exercise real-world concurrency and data volumes. Each suite must plug into our existing CI/CD pipeline so that failures block the build and generate actionable reports for developers inside their pull requests. Key targets include: • Converting current manual regression cases into reliable Selenium scripts...

...tightens security by controlling app permissions automatically, based on user-defined conditions rather than simple allow/deny prompts. The idea is to intercept any permission request at runtime, check it against a rule set (time, network, app state, or other triggers we agree on), and then grant, deny, or prompt accordingly— all without touching the original ROM. Scope – Develop the full module in Java/Kotlin for the current Xposed/EdXposed framework. – Build a compact UI for adding, editing, and importing rule profiles so users can craft conditions such as “Block camera when screen is casting” or “Allow location only on trusted Wi-Fi.” – Ensure rules apply instantly after creation and survive reboots. – Keep battery a...

Acceptance criteria 1. Smartphones and tablets enrol successfully and receive an initial pol...

I have a small Java Swing application where several JCheckBox components refuse to stay checked when clicked. No exceptions are thrown; they simply pop back to an unchecked state immediately. I need someone to dive into the relevant UI and event-handling code, identify why the state isn’t persisting, and deliver a clean fix that works across Windows, macOS, and Linux builds of the app. You’ll receive the current source (Maven project) plus a short video showing the behaviour. Please return: • corrected code or patch files • a brief explanation of the root cause • confirmation tests or steps I can run to prove the boxes now retain their state If you’re comfortable debugging Swing listeners, model binding, or custom renderers, this should be a ...

I need a small, self-contained resource pack for Minecraft Java Edition that will be used on a Fabric server. Very important: This project must NOT use OptiFine, Custom Item Textures (CIT), or any client-side mods. I want this to work using vanilla mechanics only. The goal is to replace the standard carved pumpkin model with several alternate 3D fantasy-style models (for example: a long wizard’s hat, a trophy helm, and other creative variants). Players should be able to switch between these models simply by renaming the carved pumpkin in an anvil. No OptiFine, no CIT Resewn, and no external mod dependencies should be required. The solution must rely purely on vanilla-compatible resource pack features. This pack is focused and lightweight. I only need: Custom textures Cus...

My multi-app food-delivery platform (React Native front ends, Java & Spring Boot backend) already runs smoothly for customers, restaurants, delivery partners and admins. I now need a secure hand-over confirmation flow: 1. When the delivery partner clicks on GET DELIVERY LOCATION, the Customer app must auto-generate a single-use OTP/Pin. 2. The code stays valid for exactly 30 minutes (time-based expiry) and the customer can trigger a fresh code immediately if something goes wrong. 3. The Delivery Partner app prompts for this code on arrival; on successful match the backend records “delivered” and releases any pending status updates to the Restaurant and Admin apps. SECOND PART: After confirmation for order from Restaurant app, all devices of DELIVERY Partner get...

...notifications and emails ahead of due dates, at custom intervals we define. Although I am open to adding payment gateways or history tracking later, this first release only needs the reminder workflow working flawlessly. I expect a clean, modern UI, role-based access for admins, teachers and parents, and secure, well-documented code. Feel free to use the frameworks you trust most for Android (Kotlin, Java or even Flutter as long as the final build targets Android), and any stable stack for the web dashboard. Deliverables: • Android APK + source code • Web admin panel with hosting instructions • Structured database schema and dump • Brief user manual and developer setup guide If you have built something similar, share screenshots or a short demo link...

I have a sizeable Java-style .properties file—roughly 1,100 English words—that needs to be rendered into standard German while preserving every bit of its structure. All comment lines appear in green and must remain in English; the only content you should touch is the white text that follows each “=”. A few technical points matter: • Back-slash line breaks () must stay exactly where they are so my application still parses the file correctly. • Keys, punctuation, and spacing on either side of “=” cannot shift. • The finished file must come back to me as a clean .properties file ready to drop into the codebase—no extra encoding issues or changed end-of-line characters. If you are comfortable handling resource bundl...

I’m putting together a quick proof-of-concept that talks directly to Tuya’s Cloud API and controls a Wi-Fi smart lock. The PoC only needs to run from the command line; no UI, no bells or whistles—just clean Java code that logs every request and response in plain-text so I can see exactly what’s happening under the hood. Here’s what the program must do, in sequence: • Authenticate with Tuya Cloud using my API Key credentials. • Create a temporary password on a designated lock that is valid for exactly one hour (now → now + 1 h). • Immediately fetch and print the list of existing temporary passwords so I can confirm the new one is present. • Delete that same temporary password and verify its removal. I can supply Tuy...

I need a dedicated software developer to build a polished Android mobile application from the ground up. I already have the core concept and basic feature list sketched out; what I’m missing is an expert who can translate that vision into clean, efficient Kotlin / Java code, craft an intuitive Material-compliant UI, and guide the app right through to a signed Play-Store-ready build. Here’s what success looks like to me: • A fully functional Android app that runs smoothly on current OS versions and common screen sizes. • Well-structured source code pushed to a private Git repository with clear commit history and inline comments. • Lightweight technical documentation (set-up steps, build instructions, and an API overview if external services are used)...

I have a freshly-created React Native project that refuses to build on my Windows development machine. Gradle fails during the Android build step, so the app never reaches the Android Emulator. I’m using Android Studio “Otter” alongside the standard Android Emulator and current Java JDK. Here’s what I need from you: • Inspect my current environment remotely (screen-share or a quick pair-programming session). • Identify and resolve the Gradle errors that block the build. • Verify that the project compiles, installs, and launches in the Android Emulator without warnings. Help me with apk generation. • Leave me with clear, step-by-step notes so I can reproduce the setup if I reinstall or move machines. A background in React Native CLI ...

...changes inside the UI. I2S handling can follow later, but rock-steady I2C comes first. You may choose any practical route—GPIO lines available on an Android SBC, a USB-to-I2C bridge, or another proven method—so long as it runs on a stock Android build. I can supply the amplifier’s data-sheet and register map as soon as the project starts. Deliverables • Full Android Studio project (Kotlin or Java) with clean, well-commented source • Working APK that finds the amplifier at its I2C address, reads/writes at least one test register, and visually reflects the change • Remote key handling that reliably adjusts an on-screen EQ parameter • Brief setup document covering hardware hookup, build steps, and pointers for adding future I2S support...

...function is a clear, intuitive snack-selection menu. The flow is simple: users open the app, browse categories or search directly, tap an item, and add it to a lightweight cart. At this stage I am not including in-app payments or review screens, so your effort can stay focused on perfecting the menu experience, item imagery, and quick navigation. Key points to cover • Native Android build (Kotlin or Java—whichever you are faster with) • Simple, modern UI that fits Material 3 guidelines • Category filter, search bar, and product detail pop-ups with image, price, and short description • Local data storage or a small Firebase/SQLite back-end so items can be updated without a new APK push • Clean, well-commented code and an APK for testing S...

I have an existing Java Swing frame that lists data in a JTable. I’d like you to extend that frame (no full refactor) so it keeps the first three legacy columns exactly as they are and adds two new checkbox columns: one for single-select, one for multi-select. Behaviour to build • Load: merge the current GET call with a specific stored procedure I will supply, then set the two new checkbox flags as the rows arrive. • Filters: the small header text fields already present must filter with strict AND logic; results should affect only the rows currently visible in the table. A separate global search box should apply the same AND logic across all visible columns. • Header checkboxes: when a user clicks the checkbox in either new column’s header, toggle t...

I need a Java developer to wire my existing trading platform directly into Interactive Brokers’ Trader Workstation (TWS) so I can operate both Individual and Business accounts from the same codebase.

I will give you a working Android application that I own the rights to and need it rebuilt from the ground up. All screens, flows, wording, colours, animations and behind-the-scenes logic must match the reference exactly, so a user moving between the two apps notices no difference. You are free to use Kotlin or Java in Android Studio as long as the finished code is clean, well-commented and ready for future updates. If the original app relies on a simple server or local database, mirror that structure; if it calls external APIs, point the new build to the same endpoints. I will supply any keys or assets you need. Deliverables • Complete Android Studio project with source code • Release-ready APK (and, if possible, an App Bundle) • Brief build/run instructions so...
