...comments—all delivered with a clean Material Design interface and smooth performance on modern Android devices. You’re free to choose Kotlin or Java, but the code must be written in Android Studio, clearly documented, and structured for easy hand-off. For authentication and cloud storage I’m leaning toward Firebase, yet I’m open to your technical suggestions if they simplify scaling and keep costs reasonable. Security, responsive layouts, and thorough testing are essential; I’d like the first APK to be stable on Android 8.0 and above and ready for submission to Google Play. Deliverables • Complete Android Studio project with readable source code and compiled release-ready APK • Basic technical documentation (build st...
I run an industrial engineering firm delivering heavy-duty fabrication and installation packages to the mining sector, and I need an experienced Welding Quality Control Inspector who can split time across our Germiston, Kliprivier and Meyerton sites. The engagement is deliberately light-weight—around four hours a day, three days a week—and perfect for a freelancer who wants steady site work without locking into a full-time post. Your mandate covers both fabrication shop welds and field erection welds. You’ll verify compliance of SMAW, GTAW, GMAW and FCAW joints, interpret welding symbols and drawings, perform visual examinations (VT) at root, intermediate and final stages, and flag any non-conformances against the specified acceptance criteria. Each visit ends w...
I have twelve floor-plan PDFs that show every workstation in the building. I need each file reviewed, every desk counted, and the map divided into visual sections of roughly 100 desks apiece. Once the groupings are set, apply a distinct outline color to each section so it’s obvious where one block ends and the next begins. Exact counts aren’t required—an approximate target of one hundred desks per color block is fine. Feel free to choose any palette as long as neighboring sections are clearly distinguishable. When you’re done, return the updated PDFs plus a simple spreadsheet that lists, for every color on every floor, the desk total you arrived at. Accuracy in counting and a clean, professional look on the final visuals are the key success measures. Acrobat, Blue...
I have a small AGV platform running on an Arduino Uno, two DC motors driven by an L298N bridge, and a pair of HC-SR04 ultrasonic sensors mounted up front. I already have the hardware wired and tested; what I still need is clean, well-documented embedded-C code that lets the robot detect an approaching obstacle with the ultrasonics and autonomously steer around it. Functionality • Primary mode must be obstacle avoidance; no line following or remote-control features are required at this stage. • When the sensors report an object within the safe-distance threshold, the robot should smoothly adjust course and continue forward rather than simply stopping. A simple state machine or PID-based turning logic is fine as long as the movement looks deliberate and repeatable. Imp...
...engagement is not a small website or a prototype. It is a long-term, enterprise-level platform that will power customer applications, driver operations, admin systems, inventory flows, order lifecycles, payments, and real-time delivery tracking. The backend APIs will be the core foundation of the entire business. The backend system must be developed strictly using Java and the Spring ecosystem (Spring Boot, Spring Security, Spring Data, Spring Cloud where required) and follow a microservices-based architecture. All services will communicate through secure, well-documented REST APIs, using internal JWT-based authentication and industry-standard security practices. We are looking for freelancers who can take ownership of backend services end-to-end, including system design...
I’m building a small, purpose-driven billing app that will run on Android phones and tablets. The flow is simple: I type in each sale, the data is stored in our Miracle database, a polished PDF invoice is generated on-device, and I can print or share that file immediately. Core requirements • Manual data entry screens built around a clean, straightforward UI • Automatic daily and monthly revenue totals, plus a sales-report screen with date-range filters • Real-time (or deferred, if offline) write-back to the existing Miracle DB schema • One-tap PDF creation that mirrors our invoice layout and supports native Android printing/sharing Reports Because “Sales reports” is the only extra feature I selected, the app just needs co...
I need a skilled Java developer to turn my desktop-application idea into a working program. The core requirement is straightforward: the finished app has to run reliably on Windows and macOS, install easily, and offer a clean, intuitive interface. You are free to pick Swing, JavaFX, or another modern Java UI toolkit as long as the end result feels native and responsive. I will share mock-ups, a concise feature list, and sample data once we start. What I expect back is the complete, well-commented source code plus a packaged executable (JAR or native installer) that passes a quick smoke test on both operating systems. If you’ve built polished desktop tools in Java before, I’d love to see one or two examples along with a brief note on the fram...

Our payment gateway has approved Website B for payment collection. We also have Website A, where customers place orders. During checkout, we redirect the customer from Website A to Website B to complete the payment. Once the payment is successful on Website B, it sends a confirmation/response back to Website A, and the order status is updated accordingly on Website A. Important: The payment gateway should only see and process transactions on Website B. It should not receive or track any direct request or integration reference from Website A when the customer is redirected for payment.

I’m building a custom Android application whose entire business logic will flow through remote APIs, and I need someone who can own both sides of that interaction. On the mobile front, you’ll craft a clean, responsive Android app (Java ) that consumes the endpoints I provide. On the tooling front, I rely on POSTMAN for every stage of the back-end integration, so your day-to-day will include importing the collection, refining environments, and, most importantly, running the automated test suites inside Postman to make sure each call performs exactly as expected. The scope is straightforward: create the app screens, hook them up to the API, then validate the whole flow by executing and, where needed, extending my existing Postman tests. If you’re comfortable living ...
