Summary
🤩
Rockstar🎓
Top SchoolMarcelo Lazaroni is a Principal Engineer with 11 years of experience building high‑impact systems across fintech, search infrastructure, and consultancy projects. A Haskell specialist by trade, he has applied functional programming to derivatives pricing at Standard Chartered and to large‑scale code search and indexing at Meta, including work on the Angle compiler for the Glean database. Marcelo blends deep technical craft with delivery leadership—he led frontend restructures that dramatically cut bugs and build times and directed a consultancy team that built a CRM for a multi‑billion pound advisory firm. Now based in Porto, he continues to marry rigorous engineering (and a dry “almost harmless” sense of humor) with pragmatic product outcomes as Principal Engineer at Ambar.
