What I'm looking for

I’m looking to lead cloud-native backend migrations and scalable microservices on Azure/AWS, using event-driven patterns and applying LLM/RAG tooling to accelerate legacy modernization and data processing—within a team that values engineering rigor.

I’m a Senior Software Engineer who leads modernization of legacy systems into cloud-native, serverless architectures. At Skyworks Inc., I own the Atlas Project’s technical direction—building backend services and parsers, architecting Azure Functions-based replacements, and integrating LLM/RAG through Model Context Protocol (MCP) servers to accelerate legacy code analysis.

Previously, I built high-performance backend microservices at Stone Co. using Go, including RESTful/gRPC APIs, PostgreSQL schema and query optimization, and event-driven architectures with Apache Kafka. Earlier, at Vivo (Telefonica Brazil), I processed and extracted insights from massive IoT datasets (millions of devices, terabytes daily) using Python, Golang, Azure, and data systems like SQL and MongoDB—turning operational data into actionable decisions.
