Summary
🤩
Rockstar🎓
Top SchoolFabio Dal Castel is a seasoned CTO with over 20 years in IT and 13 years of hands-on engineering experience, currently leading technology at DATAWEB Tecnologia from Rio Grande do Sul, Brazil. He combines deep systems knowledge from early Delphi/Oracle enterprise work to modern compiler and full‑stack development, favoring pragmatic, code-first solutions ("Talk is cheap. Show me the code."). As a notable contributor to the Fable compiler, he implemented language-level features and cross‑target translations that bridge F# and JavaScript ecosystems, demonstrating fluency in both functional languages and JS runtimes. Fabio is comfortable moving between architecture, product needs, and low-level implementation details—fixing NUnit plugin bugs one week and adding Enum comparison or array blit semantics the next. He brings a long track record of shipping reliable, production-grade enterprise software and a conviction that shipping working code trumps buzzwords.
