I build scalable backend systems that reduce costs, latency, and operational risk.

What I'm looking for

I'm looking to build scalable, intelligent, cost-efficient backend systems, particularly where cloud architecture, performance optimization, and AI integration can create measurable business impact.

I've built high-performance financial services and e-commerce systems at GFT Technologies, Mercado Livre, AB InBev, Accenture, and 7COMm.

At GFT Technologies, I architected AWS serverless infrastructure with Terraform that reduced cloud costs by 25%, improved API response times by 35%, and introduced Datadog observability that reduced mean time to detection by 40%.

At Mercado Livre and AB InBev, I led a Golang-to-Java migration, designed components used by five-plus teams, integrated Kafka for lower-latency processing, and delivered Java/Spring Boot API improvements that cut infrastructure costs by 50% and response times by 45%.

I bring a background in finance and corporate banking alongside backend engineering, and I’m especially interested in applying LLMs, RAG, and agentic systems to build intelligent, cost-efficient products.
