Summary
Systems Engineer and full stack developer with 4+ years building mobility and public transport solutions in Córdoba, Argentina: taxi apps, public bike sharing and city services. I was the first developer on my team and now lead it technically, in a team of 4.
I cover the full cycle: client discovery, database design, web and mobile development, and deployment with Docker and CI/CD on self-hosted infrastructure. Strong experience with maps and geolocation using self-hosted services (Traccar, Nominatim, GraphHopper).
Experience
Technical Lead & Full Stack Developer — Micronauta (Globalvisum)
Jul 2022 – Present
- Joined as the only developer; the team grew to 4 and I now lead it technically, with context across every project.
- I start new projects, take them to an advanced stage, hand them over for maintenance and keep leading their evolution.
- Main technical contact for management and clients: I demo products, define scope, defend proposals and negotiate integrations.
- Migrated the driver app from a hybrid web app to React Native with native hardware access: lower RAM usage and a faster app. Live with Rapitaxi (~500 drivers) and rolling out in San Juan.
- Led the team's mobile evolution from PWAs to Capacitor, then React Native. I publish and maintain apps on Google Play, and built the taxi app for iOS with Capacitor and Codemagic.
- Design project databases and optimize performance-critical queries.
- Integrated Mercado Pago payments, VEDI services and Córdoba City Hall systems over VPN.
- Set up self-hosted GitLab with CI/CD, registry and runners, and dockerized every application for tag-based deploys with rollback.
- Lead the server and security monitoring project (Prometheus, Grafana, Alertmanager, n8n).
- Trained new hires and other departments in Git, Jira and Docker for ISO certification.
