Hi, I'm Sergi.
2000 — PRESENT
I'm just a SWE passionate about technology and entrepreneurship.
Every line of code is a piece of your (a)imagination brought to life. Dare to build, and you’ll create products that inspire others to dream even bigger.
I'm a creative, open-minded engineer with a strong passion for technology and a love for tackling challenges. Over the years, I've worn many hats, from Senior Frontend Engineer, Web Engineer, and Backend Engineer to Sysadmin and IT/Engineering Manager, gaining a broad and versatile skill set across the tech landscape.
I'm deeply engaged with startup culture and the entrepreneurial ecosystem, constantly exploring how innovation can drive meaningful change.
