...Frequency Drive is running on existing code that now throws unexpected errors during operation. I need an experienced developer to dive into the current project, isolate the bugs, and deliver a clean, reliable version of the program that restores full functionality. You will have remote access to the controller and the full source package as soon as we agree on an NDA. Once inside, I expect you to: • trace and document the root cause of the faults, • correct the offending sections of code, and • verify the fix on-site or through simulated load tests so the drive performs to spec across all speed ranges. The job is complete when the code compiles without warnings, the VFD responds accurately to every command sequence, and I recei...
I’m creating an online store for cosmetic products and want the codebase to feel as professional as anything you would ship to production. The backend must be written in Java with Spring Boot, exposed through well-structured REST endpoints, and persist data in MySQL. On the client side I only need a clean, responsive interface built with plain HTML, CSS and vanilla JavaScript—no heavy frameworks—so that the focus stays on clear architecture rather than flashy UI libraries. Core features I expect: • Role-based authentication for Admin and Customer accounts, supporting registration, login and logout with secure password storage. • Admin dashboards to add, edit and retire products, plus view basic order information. • Customer-facing catalogue with...
I’m expanding several engineering teams for top-tier MNCs and rapidly scaling tech start-ups and need skilled people who can jump in right away. The first seats I must fill are: • Software Developers who are fluent in React, Node, and/or Java. If you can architect front-end components in React, build robust APIs with Node, or craft enterprise-grade services in Java, you’re already on my shortlist. • Data Analysts & Data Engineers able to turn raw data into clean, actionable insights. Solid SQL skills are essential, and if you have experience with Python, Spark, or comparable tooling, that will be an added advantage. • UI/UX Designers who can translate complex product ideas into polished, user-centric interfaces, balancing aesthetics with ac...

...endpoints and make the tablet experience fully in step with the web version. Because this is a contract role I need someone who already has at least five years of hands-on APK work under Linux—comfortable with Android Studio, the Android SDK, Kotlin/Java, Git, and typical CI pipelines. You should be able to stand up a clean architecture, guide me on best practices for tablet UI/UX, and hand over production-ready code.

...attendance records, and grades/performance, all pulled from our current REST endpoints. Data caching, photo upload, and simple edit forms already exist in Java and must be replicated in Dart without losing validation rules. 3. School Contacts & Calendar – For this first sprint I only need the staff directory portion live. Search, role filtering, click-to-call, and email links should work out of the box. The calendar view may stay read-only for now; it simply has to render the same event feed we already expose in JSON. You have to use same Android source, API codes (Extract), and the original UI assets. Keep the file and folder structure Flutter-standard, comment the code clearly, and ensure it builds for both Android and iOS (latest stable cha...

This project centres on building a native Android application from the ground up. The exact domain is still open—whether the final product supports e-commerce, social networking, education, or another category will be decided once we refine the concept together. Key functionality is equally flexible. Depending on the agreed use-case, the build may include fundamentals such as messaging, user profiles, a news feed, or any other feature set that fits the solution. Code should be written in Kotlin or modern Java within Android Studio, follow current Material Design guidelines, and be structured for easy maintenance and future feature expansion. Deliverables • Fully-tested APK and complete source code • Brief technical documentat...
...seamless photo sharing, and a robust friend-connection system. Because we’re targeting Android only, you’re free to lean into Kotlin or Java and make the most of Google-first services—Firebase for real-time chat and push, Play Games Services for leaderboards or achievements, and any modern Android Jetpack libraries that speed development while keeping the codebase clean. I’ll handle concept art and copy; you’ll take charge of architecture, clean UI/UX, feature implementation, and release-ready optimisation. Reusable, well-documented code is important, as I want the flexibility to add more mini-games or utilities later. Deliverables • Complete Android Studio project with clear package structure • Signed, ready-to-upload A...
I maintain a Java-based backend that exposes a small REST interface for sensor and other device data. A few legacy issues are breaking current GET and POST calls and I also need several new endpoints added. Each confirmed bug you resolve is paid at ₹1,200, and the same rate applies if you prefer to log time hourly instead. Scope • Diagnose and fix existing errors in the REST layer, services, or related model classes. • Add clean, well-documented GET and POST endpoints so devices can reliably push data and consumers can pull it back. • Ensure responses follow our current JSON schema and return the correct HTTP status codes. • Provide concise unit or integration tests that demonstrate each fix or new endpoint working end-to-end. Acceptance criteria A pu...

I have a collection of videos that don’t fit neatly into the usual “corporate,” “YouTube,” or “event” labels, yet they all share one common goal: they must look polished, seamless, and uncluttered. I’m looking for an editor who can take raw footage of varying subjects and shape it into a cohesive final product with a simple, clean feel—no flashy effects, just thoughtful pacing, smooth cuts, and an overall professional finish. You should be comfortable working with different formats and resolutions, maintaining consistent color and audio levels, and exporting files that are ready for immediate upload or distribution. If you prefer Premiere Pro, Final Cut, DaVinci Resolve, or another mainstream NLE, that’s fine; what matters...
I have a growing collection of peer-reviewed papers that I need to turn into structured insight rather than long PDFs. The core objective is to build (or fine-tune) an artificial intelligence model that can read scientific articles, understand their content, and return usable analytics. In practical terms, the system should ingest batches of text-based research papers, then automatically extract key findings, highlight recurring themes, and provide concise summaries that I can export for further work. Because the project is about analysing data—specifically text data from scientific literature—I expect strong natural-language-processing skills with Python, Hugging Face Transformers, spaCy or similar libraries. Experience with science-specific language mode...
...for a ready-to-deploy ERP package, complete with 100 % editable source code, that I can roll out across multiple manufacturing facilities. The platform must be purpose-built for a manufacturing environment; streamlining day-to-day operations is my primary objective. Core scope The system has to cover the usual breadth of a full ERP, but the first three modules below are non-negotiable because they drive our shop-floor efficiency: • Inventory Management • Supply Chain Management • Production Planning If your codebase already includes additional standard modules—finance, HR, CRM, maintenance, or quality—let me know; the broader the coverage, the better. Technical expectations and deliverables 1. Complete source code with...
...I want its look, flow, and custom price-calculator functionality reproduced on a fresh WordPress install running WooCommerce. The layout, navigation, and overall user experience should feel identical to the source while remaining fully responsive on mobile and desktop. The calculator is central: it must mirror the reference logic, update the product price dynamically, and pass the correct amount straight into the WooCommerce cart and checkout. Clean, well-commented code is essential because I will be maintaining the site after delivery. Timeline is tight—everything needs to be finished, tested, and ready to hand over within 3 days. Deliverables • Pixel-perfect replication of the reference design on WordPress + WooCommerce • Custom price ...

...controls: the room creator should be able to mute or remove users, lock a room, and assign co-moderators. A simple dashboard or in-room toolbar is fine as long as the workflow is intuitive. We can start with this focused feature set—group voice channels plus admin moderation—and keep the codebase modular so we can layer in extras like private messages, file sharing, or end-to-end encryption later if the roadmap calls for it. Preferred stack • Native Android (Kotlin or Java) using WebRTC, Agora, or a comparable real-time audio SDK • Lightweight back-end (Firebase, Node, or another cloud service) for user auth and room state Deliverables - APK and Play-Store-ready bundle - Full source code with README covering build steps, thi...
