Product engineer · Barcelona

Damián Crespi

I build products end to end, from a rough idea to something people rely on. My depth is in frontend architecture and performance, on everything from web apps to smart TVs.

I’m a senior frontend engineer at Delivery Hero. On the side, I build and run my own products.

Now

Outside of work I ship small products to test whether an idea holds up. Lately that means personal-finance tools and small agents that handle my notes and reminders.

Available for freelance and consulting work. Email me.

Projects

Descuentazo

I built and run Descuentazo, a deals aggregator for shoppers in Argentina. An LLM pipeline writes the deal copy, and a browser extension converts Amazon prices into pesos.

It reaches 30,000+ monthly users and earns from affiliate links and ads. Browse the deals at descuentazo.com.ar.
