Quantitative Technologist
Amsterdam, North Holland, Netherlands
Summary
👤
Senior🎓
Top SchoolLessandro Mariano is a pragmatic quantitative technologist with 15 years of experience building developer productivity, build systems, and resilient infra for trading and large-scale services. He’s a polyglot engineer equally at home in C++, Haskell, Python and JVM/JS ecosystems, with deep expertise in Bazel migrations, monorepos and DevSecOps that drove a 98% reduction in build and test time at Philips Hue. At Google he led large-scale source-control migrations and reliability work for Gerrit/Git, and most recently applied that tooling mindset to quantitative trading infrastructure. Lessandro combines low-level systems know-how (embedded Linux, networking, sanitizers) with a security-first, functional-programming bent, often solving thorny debugging problems end-to-end. Based in Amsterdam, he favors pragmatic automation and reproducible builds to boost developer velocity across complex, polyglot codebases.
