ABOUT
Freelance frontend developer based in London. I build websites and web apps for small businesses and SaaS startups.
Freelance frontend developer in London. Websites and web apps for small businesses and startups.
I'm Alvaro, a Spanish developer living in London. I specialise in React, Next.js, and TypeScript — building fast, modern websites that rank on Google and convert visitors into customers.
Before freelancing, I spent years as a senior frontend developer shipping production code for dashboards, payment flows, and real-time trading interfaces used by thousands of people daily.
I've won four ETHGlobal hackathons — Brussels, Lisbon, New York, and LFGHO. Building under pressure taught me to ship fast without cutting corners.
Now I help small businesses get online properly and SaaS founders ship landing pages that actually convert. One developer, no agency overhead, fixed prices, fast turnaround.

BEYOND CODE
I believe good code is a craft — it should be functional, elegant, and built to last.

Outside of work, I train Brazilian Jiu-Jitsu. It has nothing to do with code, but it teaches patience, problem-solving under pressure, and knowing when to let go of a bad position. All useful.
