About me

Team Engineering lead with over 7 years of experience in software development, currently based in Spain. My background is rooted in frontend development, but over the years I’ve grown into full-stack work and team leadership. I focus on guiding developers, improving processes, and delivering solid, maintainable products that solve real-world problems.

Throughout my career, I've been hands-on with technologies like React, Next.js, TypeScript, Node.js, and Storyblok, leading projects that range from complex migrations to high-impact feature development. I care about clean code, performance, and building products that last. Above all, I believe in growing strong teams, encouraging collaboration, and keeping things simple and effective. If you're into building great software with a focus on people and product, we’re already speaking the same language.
