Software Engineer

Software that has to work.

I maintain clinical laboratory systems in production, where a wrong result has consequences for a patient. I build and run my own infrastructure with the same discipline: 25 subdomains and 16 services live right now on a server I administer alone.

Three fronts

Healthcare software

Laboratory Information Systems (LIS): pre- and post-analytical workflow, quality control with Westgard rules and outlier tests, statutory reporting under Chilean health-ministry regulation.

Platform & infrastructure

A VPS I run end to end: Caddy with automatic recovery, systemd user services, monitoring, backups and deploys. I do not just write software — I operate it.

Applied AI

Computer vision over video — pose estimation validated against manual annotation, real-time object detection — and agent automations I use daily. Trained in machine learning through Stanford/DeepLearning.AI and in LLM application development.

Featured work

Each one ships with source, a demo, or a live service you can check yourself.

Gonio Shard

Measures joint range of motion from a browser camera — no goniometer, no sensors. It began as my 2024 thesis, and revalidating it showed the result I had reported was wrong.

Shard Ecosystem

25 subdomains and 16 self-built services running on a VPS I administer alone, without root access. Including the outage that took down 26 sites at once, and the self-healing mechanism that came out of it.

Shard VPS

An Android app to run my server from my phone: a full SSH terminal via xterm.js, a PC key row above the soft keyboard, and a list of live sessions to resume.

Book Post

A Canva-style editor for building book-cover posts: search a book, drag elements onto a 1080×1080 canvas, export a PNG. With passkeys instead of passwords.
