At Certsys - Caixa Econômica Federal, I lead the architecture and ongoing development of the Payments Journey Micro Frontend for a next-generation mortgage platform. I built financial workflows for installment management and payment simulations, replacing manual steps with automated recalculations.

I also designed a telemetry platform integrated with Azure Application Insights to capture exceptions and business events. It was later extracted into a shared library and adopted across multiple Micro Frontends.

At TESS AI, I delivered capabilities for an enterprise Generative AI platform, including multi-agent conversations and document ingestion for Retrieval-Augmented Generation. I also implemented real-time response interruption across the frontend, backend, and database layers.

At Oya Care, I developed internal platforms for clinical operations, including automated clinical report generation and a unified medical consultation workspace. The report workflow reduced operational effort by 90%; I also implemented serverless workflows using AWS Lambda, Amazon SQS, Amazon SNS, and Amazon S3.
