00 Profile

I build fast, accessible interfaces in React, Next.js and TypeScript, and I know enough Node.js to ship a feature end to end.

01 What I do

Frontend Engineering

Responsive, accessible UI in React, Next.js and TypeScript — shared component libraries and design-system rigor.

Full-Stack Delivery

Node.js, Nest.js, GraphQL and SQL/MongoDB behind the interface, so I can take a feature from the database to the UI.

Technical Leadership

Tech lead work: architecture, code review, mentoring, and keeping delivery on schedule.

Performance & A11y

Core Web Vitals, accessibility that actually works, and tests in Jest & RTL.
