At Loja City Hall, I optimized mission-critical Spring Boot microservices to handle a 40% surge in concurrent requests while maintaining low server latency. I also implemented Keycloak-based access controls for public services and tuned PostgreSQL queries for public records.

At Monarka System, I led the migration of a legacy desktop billing system to a cloud-native ERP web application, using NestJS, Next.js, Docker, and AWS EKS. Earlier, at Juntapuntas and Nymbusoft Technology, I developed financial APIs and processing pipelines and improved database performance.
