About

I'm a software engineer focused on backend development. I work mostly with Go and Python, building APIs and services, and I have hands-on experience with search engines on Elasticsearch, from my early days at Empathy.co to today.

Most recently, at Prendeluz, I built the backend of an in-house ERP and helped create Velocraze, an e-commerce marketplace, building its Elasticsearch index backend and the Solver feature. I also took part in architecture decisions and deployments with Docker and Jenkins.
