I'm Leonardo Costa — a full-stack developer working mostly with Node.js, TypeScript and React. I'm currently a Full-Stack Developer at Zenode.ai, a Silicon Valley startup, and I also run my own software consultancy.

I'm an MSc student in Production Engineering at PPGEP/UFF, where I work on multicriteria decision analysis, linear & integer programming, data analytics and deep learning. What I enjoy most is the overlap: software engineering on one side, operations research and decision science on the other.

Outside of dev: cycling, my cats, competitive games and tcgs
