Rockstar🎓
Top SchoolKostis Anagnostopoulos is a seasoned software engineer and architect with 12+ years designing scientific and simulation software for the European Commission, currently mentoring heavy-duty vehicle CO2 simulation at JRC. He blends deep back-end Python expertise with systems thinking—having architected DG CLIMA’s CO2MPAS and contributed to widely used open-source projects like PyTables, GitPython and traitlets. Comfortable across MATLAB, C# and DevOps, he improves tooling, logging, and developer ergonomics while ensuring robust testing and cross-platform reliability. An avid maintainer of debugging and autocompletion improvements, he’s contributed pragmatic fixes that make large-data and state-machine libraries easier to use. Early hacker instincts (from Amstrad demos to Arduino virtual-DOM experiments) underpin a curiosity-driven approach to engineering. Passionate about climate impact—both professionally and personally—he frames technical work as practical climate action.
