Hi, I'm
Roi
Software Engineer & Serial Builder
SaaS platforms, mobile games, tech tutorials — if it can be built, it's probably on my to-do list.
About Me
A passionate engineer who builds, teaches, and creates
I'm a Software Engineer based in London, originally from Galicia, Spain. With over a decade of experience, I've worked across startups and large enterprises, building scalable systems and leading engineering teams.
My journey has taken me from Krakow to Barcelona, then around the world teaching software engineering bootcamps in Mexico and Bali, before landing in London. Along the way, I've built SaaS platforms, published mobile apps and games, started a tech blog, and launched a YouTube channel.
I'm passionate about clean architecture, developer experience, and turning ideas into polished products. When I'm not coding, you'll find me exploring game development with Godot or writing about software engineering.
