Problem-first software studio

Problems in.
Production out.

Every AMONCA product started as a real operating problem — sourcing too slow, billing scattered, lists nobody could read. We design, build and operate the software that retires it: APIs, SaaS and apps running in production today.

Under the hood

The pretty part is the shallow end.

Every AMONCA product sits on the same engineering discipline: typed APIs, boring-on-purpose infrastructure, and observability from day one. The interface is what clients see — this is what keeps it standing.

The studio

One roof, zero hand-offs.

AMONCA is the studio of Alex Montesino — a backend developer and API specialist who'd rather retire a problem than bill hours, taking products from first schema to production traffic. No agency layers: the person who designs your API is the one answering when it pages.

How we work

Three steps. Zero hand-offs.

01Intro call

Thirty minutes on the problem — what it costs you today, honest feasibility, and whether we're the right fit.

02Fixed-scope build

Design, API and app under one roof, with a working demo in your inbox every week.

03Operate

Deployed, monitored and alerted from day one — the same infrastructure our own products run on.
