What I'm looking for

I seek roles building scalable observability or backend platforms, focused on reliability, cost optimization, mentoring, and measurable system improvement.

I am a senior backend engineer with strong expertise in Golang, distributed systems, observability, and cloud platforms. I design and build high-throughput, low-latency observability platforms and microservices that improve developer productivity and reduce operational costs.

At Mercado Livre I architected an OpenTelemetry-based observability platform handling hundreds of millions of events per minute, optimized Kafka and processing pipelines to significantly cut infrastructure costs, and developed cross-language tooling adopted by thousands of developers. Previously I built high-impact backend services in fintech and marketplace environments, led migrations, and implemented resilient patterns like SAGA across microservices.

I am pragmatic about clean code, maintainability, and automation, and I mentor engineers to raise team capability. I look for opportunities to solve large-scale systems problems, improve observability, and deliver measurable cost and reliability gains.
