About

Core stack is React, TypeScript and Next.js. I usually own the engineering side of a feature end to end: agreeing the API with the backend, designing the data model and frontend architecture, writing the code and taking the task through to release. Comfortable both with greenfield features and with legacy code: TypeScript and Next.js migrations, refactoring, testing, performance and build tooling. Alongside product work I run A/B experiments and read the results. I use AI tools daily: I write the project rules, hooks and skills for agents so that generated code follows the project's architecture and conventions. I verify the output through code review and tests. Code I don't understand doesn't reach the project.
