Zagreb · clients anywhere

An Argentine in Croatia, working for the world.

I was born in Argentina and live in Zagreb. I've been making software for fourteen years, and my favourite part is watching people use it. This year's projects are below, so you can try them.

Great software, for anyone.

That's the whole idea: make high-quality software something anyone can have. What used to take a bank or a Y Combinator fintech, a bakery, a hostel or a Croatian teacher can have today. Fast, good to look at, secure and in their own language.

I work from Zagreb, with fourteen years of craft and AI as one more tool, for people in any country. I'd love for the next project to be yours.

Zagreb · my studio

Emigrating turned into music for travelers.

I crossed the sea and turned it into a record.

Cruzando mares (Crossing Seas) is the first record of The Mariscal Trilogy: eleven songs of mine about leaving home and starting over in another country. It plays right here.

I got so Croatian I founded Croatiapp.

Croatiapp started when I moved to Croatia: a news board for people who just arrived, an academy, a dictionary and two iPhone apps. The courses have five characters with their own voices, and I'm one of them, the one with the street tricks. Here I am in the away kit. Watch me turn Croatian, then pick what I do.

Martín says:

Ja sam iz Argentine.
