About
Software engineer with 9 years of experience and a Master's degree from EPITA (2016). I specialize in functional programming with Lamdera and Elm, building type-safe production applications. I also integrate Large Language Models into developer workflows — including writing the very tooling I use day to day.
What I do
Lamdera & Elm
Deep expertise in the Lamdera full-stack framework and Elm. Production apps with end-to-end type safety, no runtime exceptions, hot-reloadable migrations.
Functional backends & APIs
Elixir, Ruby on Rails, GraphQL design, WebSockets, REST. Strong bias toward immutability and explicit data flow.
AI / LLM integration
Embedding Claude and other LLMs into dev tooling, prompt engineering, agentic automation, custom Claude Code workflows.
