Builder, fractional CTO, and co-founder of Radical.so. I work with founders in the messy first months — when the architecture, the team, and the product are all still being argued out.

Hello — I'm Ignacio.
I build digital products alongside founders.

I'm the CTO and co-founder of Radical.so — a software development studio rated 5.0/5 on Clutch that has shipped 10+ products across health, crypto, community, fitness, e-learning, and AI.

With 7+ years in the industry, I've guided products from concept to production — specializing in React / React Native, Node.js, AWS cloud infrastructure, and AI integration (LLMs, RAG, vector databases). I also work as a fractional CTO for early-stage teams that need senior judgment without a full-time hire.

My approach mixes technical depth with business intuition: I want the architecture to scale, but more importantly I want the thing we're building to actually solve a real problem for real people.

where this goes

What I'm pulled toward,
and where this all goes.

I think the next decade belongs to small, opinionated teams shipping with the leverage of modern tools — builders who can also do business, designers who can also do strategy, founders who actually understand the system they're building.

That's what I want Radical.so to be: a tight studio that partners with founders early, ships with care, and treats taste as a discipline. Along the way I've also co-founded MoonBoots — currently on pause, but built around a thesis I still believe in: that online communities deserve better than what mainstream social platforms give them. One I might pick back up when the timing is right.

What I care about, long-term, is simpler than a roadmap: doing work that compounds, and being genuinely useful to the founders I get to work alongside.

Building

Tools that compound.

Watching

Small teams,
big taste.

Learning

Less code,
more leverage.

Avoiding

Loud,
fast,
hollow.
