Software engineer · Building since 2009 · Gran Canaria, ES

Most projects don't failbecause the code is bad.They fail before any code is written.

I'm Zoltán — the engineer founders bring in when they need someone who'll push back on the spec, not just execute it.

Sixteen years shipping web apps with Node.js, Next.js, and good judgment. Solo on small bets, embedded on bigger ones. Either way, I deliver working products — not tickets closed.

/ How I work

Three things you get
that an agency won't promise.

01 / Discovery first

Before a line of code, we figure out what you actually need vs. what the requirements doc says. Half the time, the right move is building less.

Saves: weeks of rebuilds

02 / Solo or embedded

End-to-end on small projects (idea → production, one person). Or plug in as a senior IC on bigger teams — Slack, Jira, GitHub, async-first.

Modes: lead · embed

03 / You own everything

Repo, infra, env vars, domain, deploys — all in your name from day one. When the project ends, you can walk away or hire anyone to continue.

Ownership: 100% yours
