Summary
🤩
Rockstar🎓
Top SchoolAlp Mestanogullari is a Senior Quantitative Developer with 16 years of experience building reusable tools and distributed systems, currently based in France. Trained in mathematics, he turned an early passion for programming into a career focused on robust abstractions, reusable libraries, and production-grade Haskell systems. He has shipped infrastructure across finance, fintech and consultancy roles—co-founding startups and leading R&D teams working on WASM-to-ZK compilers, trustless distributed systems, and asset management platforms. A long-time contributor to major Haskell projects, Alp has made notable contributions to the Glasgow Haskell Compiler, Cabal, and the widely used servant web framework, as well as backend work on Meta’s Glean. Comfortable moving between low-level compiler fixes and high-level system design, he blends deep functional-programming expertise with pragmatic engineering for complex, data-driven products.
