Full-stack engineer, open to remote. I design, build and ship web and mobile products, and run my own SaaS.

About

I like the whole stack. The schema, the API, the pixel that is one off, the easing curve nobody asked for. I have shipped for fintech, agencies and small businesses, and now I build Oprezo, a product real shops open every morning.

Oprezo: One calendar per resource

One calendar per resource

Day and month views for every pitch, room, boat or staff member. Double bookings are rejected by the database, not by hope.

Every customer, one screen

Booking history, total spend and open balance side by side, so the owner knows who to call before they pick up the phone.
