Hi, I'm José Manuel.
Embedded Firmware & Software Engineer.
Bridging the gap between firmware, software, and applied research.
I'm José Manuel Requena Plens, an R&D engineer based in Valencia, Spain, specializing in embedded firmware (C/C++, STM32/ESP32), industrial software development, and applied acoustics research. My path runs from academic research in acoustics to industrial firmware development — and that breadth is what motivates me the most.
I thrive on integrating hardware and software end to end. I'm an active Open Source contributor whose tools are used by developers around the world, and a passionate self-hoster. My homelab serves this site and the public MCP servers anyone can point an AI client at. Check out my CV to see the full journey.
