SENIOR FRONTEND ENGINEER — OPEN TO NEW OPPORTUNITIES

I design and develop web applications from architecture to deployment.

I have spent more than eight years building applications for businesses and the public sector. I specialize in Vue, Nuxt, and TypeScript and have also worked with React, Next.js, and Angular. I improve performance and accessibility, introduce tests, review code, and document technical decisions.

01 / How I Build Software

I start by understanding the needs and requirements, then design the architecture and interface, develop the application, test it, and deploy it. Performance and code quality matter at every stage.
