Selected work · 2019 - 2026
Products I’ve shaped and shipped — usually owning both the “why” and the “how”, from first user interview to production deploy.
A solo product, end-to-end: dictate findings in clinical language, an LLM structures the draft, and a deterministic rules engine computes the classification — PI-RADS, TI-RADS, Fleischner and 24 more — always citing the official guideline. The radiologist reviews and owns every report. European-Portuguese first.
Scan Portuguese invoice QR codes on your phone, beam them to your desktop over WebRTC — no backend, no accounts. Validates against VIES and exports to CSV, Excel or JSON.
A fully-typed TypeScript client for the InvoiceXpress API — generated from OpenAPI, built on fetch with zero runtime dependencies.
A single-operator dashboard for invoicing short-stay bookings. Computes the net price from the gross stay total and the platform commission, issues sequential invoice-receipts through the InvoiceXpress API, and auto-exports the monthly SAF-T (PT) file for the tax authority.
A fully self-hosted home on Home Assistant — custom ESPHome firmware flashed to ESP32 / ESP8266 sensors, Zigbee2MQTT devices and Shelly energy monitoring, all stitched into one dashboard.
An unapologetic homelab fanatic. A Proxmox cluster runs everything as code (IaC), a k3s Kubernetes cluster handles workloads, and UniFi keeps the whole network tidy — production-grade habits, at home.
Products and internal tools I’ve built that I can’t show publicly. Happy to walk through them in a conversation.
Open source
Mostly open-source Docker containers and infra glue — the unglamorous bits that keep databases backed up and systems running.
