About Asier

I’m a Senior Frontend Software Engineer with 7+ years of experience building modern, scalable and accessible web applications, mainly with React and TypeScript. I enjoy turning complex problems into simple, maintainable solutions and being involved in the full product lifecycle, from early discovery to delivery and iterations.​

I’m used to working in small, agile and transparent teams where sharing knowledge and continuous learning are part of the culture. In my recent roles I’ve contributed to frontend architecture, led technical initiatives, mentored junior developers and helped different teams stay aligned on common goals.​​

On the technical side, I care a lot about code quality, reusable components, performance and long‑term scalability. I’m comfortable integrating APIs, working with design systems and using AI‑powered tools to move faster without compromising reliability.

I’m open to both long‑term collaborations and well‑defined short projects, as long as there is clear communication, realistic expectations, and a shared focus on building high‑quality software. Whether you need help shipping a new feature, stabilizing an existing frontend, or exploring a proof‑of‑concept with AI tools, I can step in quickly and add value from day one.
