Rockstar🎓
Top SchoolMarcos Henrich is a seasoned software engineer with 17 years of experience building full-stack and systems-level software, currently based in Lisbon. He combines strong C#, Node.js, Java, and C skills with frontend expertise in Vue and React, and practical DevOps know-how using Docker, Linux and Terraform. A graduate of Instituto Superior Técnico, he’s contributed to high-profile open-source projects like Mono—fixing core runtime and serialization bugs and improving test coverage—and helped stabilize the Sway smart-contract toolchain through compiler and tooling fixes. As a founder/engineer he designed a C# blockchain, price-crawling backends and an AI-driven trading research platform, blending distributed-systems thinking with ML experiments in TensorFlow. Notably, his work on mono-symbolicate and timezone/DateTime fixes reflects a knack for subtle, reliability-focused engineering that reduces operational overhead.
