At itti, I work on authorizations, roles and permissions. This project is the authorization engine for Ueno Bank's business payments: every corporate payment passes through it before execution, under configurable approval schemes. I've been on it since day one — defining the architecture, decoupling critical logic out of a legacy stored procedure, and wiring synchronous and asynchronous flows over SNS and SQS. Shipped end to end, from backend to mobile, with 600,000+ authorization requests processed since launch.

A centralized registry for customer records, consents and preferences at one of Spain's largest retailers. Event-driven microservices decoupled through Kafka topics, with metrics and distributed tracing via Prometheus, Grafana and Zipkin — cutting incident detection and resolution time by 25%. CI/CD automated with Bitbucket Pipelines and Docker, and complex MongoDB flows validated with Cucumber integration tests.

I co-founded Nomenclator, an AI-powered platform that automates NCM tariff classification for imports and exports across MERCOSUR. I worked on product definition, full-stack development and AI integration, turning technical sheets into tariff codes with a confidence score, regulatory justification and audit trail. The project won second place at HackITBA 2026 in the AI & Automation category. I am no longer part of the project.

I spent four years at Armaferro S.A., first working for two years as a metalworker and then for two years as a programmer. This was where I made the transition from industrial work to software development, alongside my studies.
