Message

At RBSTech, I shipped Data Maestro, a commercial platform for test-data generation, PII anonymization, and database seeding. It includes a REST API, 14 database connectors, and a Dockerized CLI for CI.

At Taller, I built Python microservices for PayPal payment processing, including transaction reconciliation and failure-recovery flows, and designed REST APIs for partner integrations.

At Tarmac.IO, I led a monolith-to-microservices migration using Docker and Kubernetes. I also designed a live geolocation service for the New York City Fire Department that supported more precise dispatch and reduced response times by 20%.

My work at Tarmac.IO also included ETL pipelines that cut processing time by 30% and backend development for a B2B SaaS platform that improved operational efficiency by 30%. Earlier, at Geru and Magazine Luiza, I worked on lending products, marketplace APIs, and logistics.
