What I'm looking for

I’m looking for work that balances technical excellence with business needs, choosing solutions that deliver real value without sacrificing quality, scalability, or maintainability.

At itti, I contribute to the backend of Upys, the company’s loyalty and benefits platform. I participated in bringing its transaction engine in-house with a serverless AWS architecture, reducing latency by 70% compared with the previous provider.

At Legendaryum, I led a three-person backend team working on user-ranking microservices. I implemented gRPC communication and Saga transactions with RabbitMQ, and helped cut delivery times by 50% through resilient GitHub Actions CI/CD pipelines.

At Consultora Pablo Barón, I contributed from the start to an online municipal services platform adopted by four municipalities. I also developed backend logic for Surtiapp’s Rally Dakar operations system and built the administration panel; I currently support programming classes at Universidad Tecnológica Nacional.
