Web solutions builder, Node.js & TypeScript
Profile
Self-taught since 2017, I bridge what people need and the code that answers it. A Node.js and TypeScript developer at Secrecy, I am interested in domain-driven design, hexagonal architecture, event-driven development, event sourcing and clean code. My next chapter will be more human, to bring a team together, champion a product’s vision or lead the commercial relationship with service providers.
