Compiling profile
>
Full-Stack & IoT Developer experienced in Modbus, M-Bus, RS485, and LoRaWAN for submetering hardware using Python, C/C++, and Bash. I have also worked on modernizing legacy systems into microservices using TypeScript, Java, and Go, with a focus on PostgreSQL and Sentry/Grafana. Beyond firmware, I have built PWAs in React and Vue, using TDD and Playwright to ensure reliability.
