Summary
🤩
Rockstar🎓
Top SchoolMarc Jakobi is a back-end developer based in Winterthur, Switzerland, with 11 years of experience building reliable systems at the intersection of renewable energy and functional programming. Currently working at tiko Energy Solutions, he applies Haskell and Nix to energy-management back ends informed by a strong academic background (MSc with distinction in Renewable Energy Systems). He has deep practical experience from research projects on PV storage optimization and has translated that domain knowledge into production software at Vela Solaris. An active open-source contributor, Marc has improved Haskell and Nix support in the popular nvim-treesitter ecosystem, notably enhancing language injections and parser stability. He cares about reproducible builds—reflected both in his tooling choices and his GitHub quip about non-deterministic builds—and brings a pragmatic, research-driven approach to shipping maintainable code.
