จาก 26,467 รีวิว ลูกค้าให้คะแนน Software Engineers 4.83 จาก 5 ดาวI need an experienced developer to review my existing Vehicle Management System and build in the improvements I have in mind. The current codebase is running well in production, but several areas need refinement: a handful of minor bugs, a couple of feature extensions, and a general clean-up for better performance and maintainability. Here’s what I expect: • First, analyse the current architecture and pinpoint any bottlenecks or obvious inefficiencies. • Next, implement the agreed-upon code changes, making sure new logic is clean, well-commented, and thoroughly tested. • Finally, package your work with a concise change log and quick-start notes so I can deploy the update seamlessly in my environment. The system was built with standard web technologies (a typical...

I already have a fully packaged code-base for an existing tool and now I need a fresh Windows desktop application that mirrors its user-interface one-for-one. You will receive the current package, screenshots of every screen, and a short walkthrough video; your job is to translate that experience into a modern, maintainable Windows executable. The core logic is in place, so the assignment is almost entirely about recreating the UI: layouts, navigation flow, dialogs, and visual behaviour. Feel free to propose WinForms, WPF, Electron, or any other Windows-friendly framework you are comfortable with as long as the final result installs easily and runs smoothly on Windows 10 and 11. Good naming conventions, clear project structure, and concise in-line comments are essential because this cod...
I have a mature ActionScript project that still runs well feature-wise, but its performance is showing its age. Right now my only priority is to squeeze every possible millisecond out of it—no new features, no general bug hunting, just measurable speed gains. Two hot spots keep holding the app back: • Loading speed, specifically during the data-processing phase after assets have been fetched. • Graphics rendering, where complex vectors and filters spike the frame time. Your task is to profile the existing code, identify the worst offenders, and refactor or rewrite sections so the initial data crunch finishes promptly and the on-screen visuals remain smooth under load. I expect you to work with typical ActionScript tooling (Flash Builder, Scout, Adobe Animate or compar...

Deliverables - Update to existing Base44 app with clean commented code - Implementation of security best practices to ensure data privacy - Brief changelog explaining key fixes and why they were made - Final pass showing the app running error-free after your updates If you’re comfortable navigating a medium-sized project and take pride in tidy code, I’d love your help.
I’m building a new digital-dentistry platform that runs on an Oculus Quest headset and I need a developer who can take it from concept to a working clinical tool written in Python. The application must combine three core capabilities: • ingest and visualise high-resolution 3D dental scans in real time, • let dental assistants walk through fully interactive treatment simulations inside the mixed-reality space, and • keep patient data organised, searchable and secure in accordance with standard privacy regulations. Everything should feel natural on-headset, so thoughtful UX decisions and solid performance tuning for Quest hardware are crucial. If you have a track record of shipping VR/MR apps and you’re comfortable driving the entire Python pipeline&mdash...

I maintain a growing web application written in both Rust and Go and I’m looking for a US-based native English speaker who can jump in confidently on the server side. The codebase relies on Rust’s Actix and Rocket frameworks alongside Go’s Gin router, so recent hands-on experience with all three is essential. Your first priorities will be twofold: shipping new user-facing features while also hunting down and patching the most visible bugs reported by our QA team. Performance tuning and architectural refactors are handled by another engineer, so your focus stays squarely on feature work and defect resolution. To make sure we stay aligned, here’s how I’ll review your work: • A concise pull request for each feature or fix, passing our existing CI tests. ...
I need ten solid pull requests merged into an organisation repo within the next week. The sole purpose of each PR is to resolve existing issues that are holding the project back, with a special emphasis on refactoring and optimisation. You are free to lean on AI-assisted tooling, automated refactor helpers or any other workflow that speeds things up, as long as the final code still feels human-written and aligns with the repository’s current style conventions. You will get access to the repo and a concise list of the open issues I consider top priority. I am not imposing any external style guide; simply mirror the formatting, naming and structural patterns already present in the codebase. Deliverables and acceptance: • Ten separate, well-scoped PRs that close or reference th...

If you have a track record of upgrading legacy web apps without downtime, let’s talk about timelines and the best toolset to get this done.
I need a clean, reliable API bridge that keeps booking details flowing instantly between Djubo PMS and Lovable in both directions. Whenever a reservation is created, modified, or cancelled in either system, the other side must receive and store the update in real-time without manual intervention. Both platforms already expose RESTful endpoints and keys; what I’m missing is the middleware logic that watches the webhooks, maps the fields, handles authentication, and writes robust error handling and retry routines so no transaction is lost. Deliverables • Node.js (or similar) service with clear, well-commented code • Field-mapping document showing how each Djubo attribute pairs with its Lovable counterpart • Deployment guide for a Linux server (Docker preferre...

I’m working with the open-source Goose Docs project () and want to release the desktop versions under my own brand. The scope is straightforward: keep every feature exactly as it is—no extra functionality—while replacing the visual identity with my company’s logo, name, and icons. Both macOS and Windows builds are required. All design assets are ready; you’ll receive the logo files, app name, and any icon variations the moment we start. Please update the splash screen, app icon, package identifiers, “About” dialog, installer graphics, and any other spots where the original name appears.

Stealth is absolutely the top priority: once the project is finished the jar must register in-game exactly as the Fabric mod “yetanotherconfig.” Nothing in its mod-id, metadata, or display name can betray the real purpose. Functionally, the jar has to run on Minecraft 1.21 under Fabric, play nicely with Feather Client, and remain fully usable on the Donut SMP and servers. Required behaviour • When I pop a totem the mod waits for a small, ever-changing delay (e.g., 0.123 s, then 0.214 s on the next pop, etc.), opens my inventory, and as soon as my cursor merely hovers a totem the item is moved to the off-hand instantly. • The routine must repeat until no totems remain. • The whole system toggles with the ‘ (apostrophe) key. I do want that key to ...

I need custom software that lets my cabinetry shop track every order’s journey—quotation, fabrication, finishing, packing and dispatch—in real time, right from our desktop workstations. The priority is simple: the moment a team member updates an order’s stage, that change must appear instantly on everyone’s screen so no one has to chase status by phone or email. The interface can be web-based or a native Windows app; whichever you feel will deliver snappy, reliable performance on standard desktop PCs. Mobile or tablet access is not required at this stage, but I would like the codebase structured so those front-ends can be added later without a complete rewrite. Key points I want to see addressed in your proposal: • An intuitive dashboard that lists all ...
I want to wire our in-house CRM directly into MYOB AccountRight so that users can press “Create invoice” and see the document appear instantly in MYOB, ready to email to the customer. The scope is deliberately lean: for this first milestone the API only has to create and send invoices with some reporting required. Environment & tech • Our CRM is custom built, so you will be working with a clean REST interface on our side. • Authentication into our stack is OAuth 2.0; the same flow should be used when talking to MYOB’s cloud endpoints. • MYOB AccountRight API documentation and sandbox credentials are ready for you. Deliverables • A documented REST endpoint in our CRM that accepts invoice data and pushes it to MYOB AccountRight. • All supporti...
I am building a Catena-X based data-exchange environment for an automotive program and need an expert who can make different partner systems speak the same language without compromising Catena-X rules. Your core mission is to design and validate the interoperability layer so that material, production and quality datasets flow seamlessly between OEMs, Tier-1s and digital service providers. Here is what I’m aiming for: • A clear, end-to-end interoperability concept covering semantic models, IDs & global identifiers, and the hand-shake logic expected by the Catena-X reference architecture. • Mapping guidelines that show how existing ERP/MES/PLM data structures align with the Catena-X data models (BOM, Traceability, CO₂ Passport, etc.). • A working proof-of-co...
I need two tightly-connected newsroom tools built as installable modules that can drop into a modern CMS (WordPress, Joomla, or Drupal—whichever you feel most confident customising). 1) Editorial Calendar & Planning The calendar must let editors line-up stories by date, assign them to reporters, and keep everyone talking in one place. At minimum it has to cover: • Content scheduling with a clear visual timeline • Task assignment that tracks status from pitch to publish • Lightweight collaboration/chat inside each story card 2) Reporter KPI Scoring Each published piece should automatically flow into a scoring engine that credits the reporter on: • Article reach • Publishing frequency • Reader engagement On top of those raw count...
