Fernando Espinosa

Software developer. 25+ years building things that work.

I build web apps, mobile apps, and APIs. Mostly for founders and small teams that want to ship without getting buried in process.

Services

web

Full-stack web apps with real business logic, real integrations, and real users in mind.

mobile

Native iOS and Android. Real native performance, not cross-platform compromises.

mvp

MVPs scoped to ship fast. Start small, validate quickly, and expand once the core thing works.

api

REST, GraphQL, webhooks, third-party integrations. The plumbing that makes products work.

Process

Most projects start in Estimo.

You answer a few questions and get a rough scope, timeline, and price. If it looks like a fit, we narrow it down and build the useful part first.

No long discovery phase. No vague estimates. Just clear scope and working software.
