I am a Senior Staff Engineer with extensive backend experience building scalable systems using Golang, Java, Python and JavaScript. Over my career I have designed and implemented high-availability services for e-commerce, fintech and large portals.
At my current role I contributed to debt renegotiation, negotiation products and multi-channel recovery platforms, driving pricing rules, product expansion and operational reach. I consistently deliver technical consistency and scalability across complex systems.
Previously I led engineering efforts at large organizations including Grupo SBF, GrupoZAP and Walmart.com Brasil, focusing on reservations and stock control, sitemap and URL control services, media management, geolocation and order management systems. I mentor junior developers, run load testing and improve CI/CD on Kubernetes and GCP.
I prioritize knowledge sharing, continuous Linux improvements and operational excellence while working with Kafka, Redis, Postgres, MySQL, AWS, Kubernetes and CI/CD tools to ensure reliable, performant production systems.
