Building tools that make programming languages more accessible, verifiable, and fun. From teaching OCaml to thousands of students to parsing the depths of POSIX shell.

I'm currently Head of Engineering working on the Tezos blockchain, a self-amending cryptographic ledger built with OCaml. My work focuses on:

• Tezos Protocol Development - Core blockchain infrastructure in OCaml, leveraging strong types for safety-critical code
• Smart Rollups - Layer 2 scaling solutions for high-throughput decentralized applications
• Tezos X - Next-generation blockchain architecture and tooling
• Formal Verification - Applying rigorous methods to ensure smart contract correctness
• Programming Language Design - Contributing to Michelson and high-level smart contract languages

"The code agents crisis adds a new parameter to software engineering: machines now also write code for humans and machines."

From punched cards to AI code agents—how each crisis in software history emerged not from lack of power, but from a mismatch between what became cheap and what remained hard. Code agents make production cheap at unprecedented scale, but they don't make meaning cheap. The next phase of software engineering will be defined by the disciplines we invent to keep capability aligned with human intent.

Key insight: For the first time, the cost of validating software can dominate the cost of building it.

"Types are not just for catching bugs—they're a language for expressing intent."

I believe in building tools that teach as they work, making complex concepts approachable without sacrificing rigor.
