Hardik J.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

Senior Embedded + Full-Stack Software Engineer who can build real hardware/software products, from controllers and processors to Raspberry Pi/Linux apps, APIs, automation, testing, and production deployment. I build production-ready software for hardware products, embedded systems, Raspberry Pi/Linux applications, microcontroller-based systems, APIs, automation workflows, and full-stack business applications. My background combines electrical/electronics engineering, embedded systems development, and 16+ years of professional software engineering experience. I have strong experience working across both hardware and software: controllers, processors, Raspberry Pi, Arduino-class systems, serial communication, Linux environments, backend APIs, databases, automation, testing, CI/CD, and long-term production support. I can help with: • Embedded software development • Raspberry Pi / Embedded Linux applications • Python backend development, FastAPI, APIs, and automation • C/C++ / controller and microcontroller development • Serial communication, hardware/software interfaces, and protocol debugging • Refactoring legacy code into clean modular architecture • Automated testing with pytest and CI/CD pipelines • Logging, configuration, deployment, and production hardening • IoT prototypes and hardware/software product development • Full-stack web applications and internal business tools In my full-time professional work, I build and maintain production software systems where reliability, security, maintainability, and long-term support matter. I also teach robotics and embedded-system concepts part-time at Clay + Code, where my wife leads the ceramic/clay classes and I teach robotics, coding, controllers, and hands-on technology. That combination gives me a practical engineering approach: I can understand the hardware, write the software, debug the interface between them, document the architecture, and help bring a prototype or internal codebase up to production quality. I am a good fit for clients who need a senior engineer who can work independently, communicate clearly, improve existing systems without breaking them, and deliver maintainable software for real products.
