Fullstack engineer at Tata Consultancy Services building software across backend, frontend, and cloud.

Brazil

Message

At GFT Technologies, I designed and developed a large-scale management platform across backend, frontend, and cloud layers. I established its backend foundation with Clean Architecture and developed services and interfaces using NestJS, Angular, and Ionic.

On another GFT Technologies project, I contributed to a property and service management platform, focusing on backend implementation, API development, and legacy modernization. I optimized database interactions to reduce API latency and restructured legacy code to improve maintainability.

At Datapage Brasil, I designed and architected a new auction platform. Earlier, at ZscanSoftware, I developed medical imaging and healthcare systems and used Python automation to improve internal processes. I currently work as a Software Analyst at Tata Consultancy Services.
