Senior Full Stack Engineer at Sidom, where I cut recurring critical bugs by 30% with AI-assisted development.

Message

At Sidom (UniendoMercados S.A.), I introduced AI-assisted development using multi-agent workflows and custom agent skills, reducing recurring critical bugs by 30%. I also met a management-set goal of 65% faster feature delivery with the same workflow.

At Laboratorios Bagó, I contributed to migrating the core platform from a monolith to microservices on Docker and Kubernetes, and implemented GitLab CI/CD pipelines. I mentored developers and took part in architecture decisions during the migration.

At Sondeos, I led the move from legacy web services to Laravel REST APIs and built the product management and activation platform for DirecTV field technicians and sales reps. Earlier, I developed features for OLX's ONEWEB classifieds platform, rolled out in 54+ countries.
