I developed and maintained microservices in Node.js (Javascript, Typescript, NestJS, Express), implemented RTK Query in React, optimized resources, integrated databases, and collaborated on UX.

I optimized microservices in Node.js and React, proposed RTK Query, improved backend performance by 80%, integrated MongoDB and SQL Server, and collaborated with product and UX teams.

I developed interfaces in React, refactored components, implemented React Hooks, and led migrations to microservices in Golang with hexagonal architecture and DDD.

I led the migration from a Node.js monolith to microservices in Golang, refactored React components, and improved the performance and scalability of APIs.

Research and evaluation of new technologies, architectural improvements, and increased test coverage in applications and services.

I improved test coverage by 70%, proposed technological improvements, and strengthened the system architecture.
