What I'm looking for

I'm looking to build and improve backend systems, APIs, microservices, and data integrations, contributing across the full development cycle in Agile teams.

At Dell through DBServer, I maintain Python and Java systems for LLM-generated data descriptions and sensitive-data compliance. I reduced LLM project execution time by 30% and increased description accuracy to 95%.

At Ambevtech, I built APIs, messaging events, microservices, and data workflows for company asset management, working with SQL Server, MongoDB, Azure Blob Storage, Service Bus, and DataDog. I also helped transition a long-running Python solution to .NET while contributing to architecture and organization decisions.

I've worked across research, internal products, and ERP development, including computer-vision POCs, IoT sensor-data systems, maintenance-ticket workflows, and C++ development. I'm comfortable owning features end to end, from business rules and testing to maintenance, debugging, and Agile delivery.
