Nero source code java jobs
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...
...microservices architecture. This 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-e...
...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 concise revenue and volume summaries—no inventory or customer modules. Export to CSV or PDF from the report view will keep things flexible. Deliverables - Complete Android Studio project (Java or Kotlin) with all source code - Miracle database scripts or lightweight API/service layer to connect the app - Signed installable APK - Short setup guide and walkthrough video or document Acceptance criteria 1. Invoices created offline sync automatically once a connection is restored. 2. PDF output matches the sample template I will provide. 3. Dail...
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...

...Core Java and Advanced Java, yet I also expect you to weave in data structures, advanced algorithms and regular competitive-coding drills so participants are battle-ready for contests. Beyond the core focus, you should be comfortable touching on Spring / Spring Boot, Hibernate, REST APIs and, time permitting, a quick primer on HTML, CSS, JavaScript or even Angular/React for well-rounded context. Eight-plus years of hands-on experience is ideal—though if you can demonstrate comparable depth and classroom presence, I’m flexible.

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 ...

...per hour. Daily voice calls are a core part of our routine, so C1+ level spoken English is essential; you’ll be talking through architecture, pair-debugging and raising questions every day. Your toolbox on the frontend must already include React and Angular. If you also enjoy the occasional Vue.js task, that’s a pleasant bonus. On the server side we run services written mainly in Python and Java, so you should feel at home designing RESTful APIs, writing unit tests and deploying through common CI/CD pipelines for at least one of those languages. Data lives in MySQL, PostgreSQL and MongoDB, and you’ll be expected to model schemas, tune queries and handle migrations confidently. Most of the current team sits in Europe, while I’m in Canada, so an overla...

...mock-ups → iterative development in Android Studio (Java or Kotlin) → unit/UI testing → a signed APK and readable source code in a Git repository. Feel free to leverage Firebase Auth, OAuth2, or another standards-compliant solution for the login layer as long as it keeps credentials safe and supports email-password plus social sign-ins. Right now I only need the Android version; however, structuring the project so it can later be extended to iOS—or augmented with push notifications and in-app purchases—will earn extra points. Clear documentation of architecture decisions, third-party libraries, and build steps must accompany the final delivery. Deliverables: • Interactive UI/UX mock-ups • Complete Android Studio project wit...

I need my existing two-storey duplex plan revised for a Canadian building-permit submission. All work has to satisfy the National Building Code of Canada, so please be comfortable detailing to NBC requirements and provincial amendments. The most critical structural adjustments are three-fold: converting the current hip roof to a 6/12-pitch gable while keeping the new profile in harmony with the home’s present style, swapping every steel beam for properly sized LVL members, and introducing below-grade basement doors on both sides complete with the extra footings those openings demand. Alongside that, floor framing must shift to conventional 2 × 10 dimensional lumber (no engineered joists) and the roof vents need to become a continuous ridge vent. On the street faç...
