Jose Hidalgo | Senior Full-Stack Engineer

Current focus

What I'm building, improving, and exploring right now.

Open to new engineering roles

Actively looking for my next role as a full-stack or backend engineer. Strongest on typed backends and the systems questions around them - scheduling, multi-tenancy, data delivery and the security boundaries those imply - with enough frontend depth to own a feature end to end.

Rebuilding this portfolio as the work sample

This site is both the job search and a piece of evidence for it. Multi-tenant Payload CMS 3 on Next.js 15, twenty collections, three structural themes switched by a single field, bilingual throughout, behind a 1,026-test gate.

Building a physiotherapy protocol tracker in Kotlin

An Android MVP for following a physiotherapy protocol through a recovery - the prescribed exercises, what was actually done, and how the injury responded. The hard part is not the data model: logging has to cost less effort than skipping it, or the history is never there when the physiotherapist asks.

Finished the AI Agents Bootcamp

Completed a hands-on bootcamp on building LLM agents: tool calling, retrieval, multi-step planning and evaluation. Came out with working agents rather than notes, and a much clearer view of where these systems actually break.
