Let's work together
Engineer with a
product mindset
8 years building fullstack products in TypeScript, across EdTech, FinTech, retail and health. I like being close to product decisions, not just the implementation.
Currently at BNP Paribas, working on the first generative AI chatbot deployed in a major European bank. Showcased at VivaTech 2025.
