Work

Things I’ve built that are in production. For each one: what was there before, what I built, and what changed. Numbers where the numbers are real, status where they aren’t yet.

01Aurasia

Aurasia

Building · 2026 — being tested with dental clinics

aurasia.es ↗

Context

Dental clinics lose the patients who write at 21:30 or on a Saturday: nobody answers until the clinic opens, and by then many have booked elsewhere.

Built

An AI receptionist on WhatsApp for dental clinics in A Coruña and Ferrol. It answers outside business hours and when the phone is busy, proposes real slots from the clinic’s calendar, prepares the appointment request and hands it to the staff, who confirm it the next morning in the same chat. It introduces itself as an AI, escalates to a person with one tap, keeps every message on EU-only infrastructure and deletes texts after 30 days. The site publishes a sourced comparison against seven competitors — including what Aurasia does not do yet.

Status

  • Live product at aurasia.es — being tested with dental clinics
  • Public, sourced comparison against 7 competitors with public prices
  • Data in the EU only, messages deleted after 30 days, processor contract signed before any pilot
  • Limits published too: no audio messages, no appointment reminders yet

02Trazea

Trazea

Co-founder · 2026 — Present

trazea.es ↗

Context

Spanish food safety regulation (APPCC) requires restaurants, bars and bakeries to keep traceability records. Most small businesses still do it on paper — slow, error-prone, and painful when an inspector asks for it.

Built

The whole product, with AI tooling in the loop at every step: a FastAPI + PostgreSQL backend, Expo/React Native apps for iOS and Android, authentication, an OCR pipeline that reads expiry dates and supplier lot numbers from label photos, an Astro marketing site, and billing.

Measured

  • Published in both app stores
  • Favorable technical report from the Food Safety Service of the Xunta de Galicia
  • Pilot running in real venues — no revenue yet
  • OCR accuracy benchmarked against real photographs, not clean data

03CoWtrol

CoWtrol

Innogando · 2022 — Present

Context

Innogando builds RUMI — GPS collars used by thousands of farmers for livestock monitoring. Behind the product, daily operations ran on five or more disconnected tools: spreadsheets for stock, a CRM nobody updated, chat threads for support.

Built

An internal platform that covers the whole operation — stock, orders, assembly, support and account management — integrated with RUMI, Holded CRM, WhatsApp Business and Telegram. Real-time stock valuation, low-stock alerts, and order-delay detection.

Measured

  • Replaced 5+ disconnected tools with one system
  • Sales stopped doing manual data entry — the CRM syncs automatically
  • Automated inventory tracking ended manual stock counts

04AI at Innogando

Slack agent

An agent that answers natural-language questions over internal databases, in Slack, built with Hermes. Questions that meant asking an engineer and waiting hours are answered in minutes, with the query visible for auditing.

WhatsApp agent

A support agent for customer queries outside business hours, answering from a knowledge base built out of real tickets and escalating to a human when it is not confident. Live with real customers.

OCR eval

An accuracy benchmark for the OCR pipeline that extracts expiry dates and supplier lot numbers. Scored against real photographs taken in real kitchens — glare, angles, curved labels — not against clean scans.

Team tooling

A shared Claude Code setup used daily by nine engineers: shared context files (CLAUDE.md, AGENTS.md), skills, hooks, slash commands and subagents, tuned to the team’s repos and conventions.

n8n automation

A lead-classification chatbot (Chatwoot + n8n) for an insurance brokerage, plus a nightly qualification pipeline running unattended — more than 1,000 qualified leads so far.

05Infrastructure

2022 — 2025

From SSH deploys to a platform: a phased database migration (InfluxDB → MongoDB → PostgreSQL) with zero downtime, CI/CD on GitHub Actions across every repo, and a migration to Kubernetes on GKE with GitOps via ArgoCD. Monitoring with Grafana and Prometheus.

Deploy frequency went from weekly to multiple times per day
