Senior Embedded Systems Engineer at Freelancer
Berlin, Germany
Summary
👤
SeniorVadim Vygonets is a Senior Embedded Systems Engineer based in Berlin with 14 years of hands‑on experience building firmware, bootloaders, drivers and Linux-based systems. He combines deep Unix and kernel-level expertise with practical hardware familiarity, routinely working on low-level concurrency, networking and security features for microcontrollers and gateways. His recent work includes automated binary rewriting for ARM Cortex‑M to harden firmware with TrustZone‑M and shadow stacks, and optimizing embedded compression code in an open-source heatshrink library. Vadim is fluent in C (and assembly), Go and classic Unix tooling, and excels at navigating large codebases to find and fix subtle, hard-to-reproduce bugs. He has led small teams on LoRa and ESP32 products, designed secure boot/FLASH encryption flows and maintained OpenWRT/FreeRTOS platforms, showing a rare blend of systems thinking and hands-on firmware craft. Colleagues rely on him for pragmatic, security-minded solutions that bridge firmware, integration and production constraints.

Contributions summary:Vadim primarily focused on debugging and optimizing the `heatshrink` library, a data compression library tailored for embedded and real-time systems. Their contributions involve fixing debug output, addressing assertions, and resolving specific edge cases related to the encoder's behavior, particularly when the window size equals lookahead. Furthermore, the user refined the encoder's logic by introducing optimizations in state transitions and reworking the decoder's internal bit processing.
