Portrait of Esteban Murcia

About

I’m a backend-focused software engineer in Colombia. Since 2023, I’ve built and operated production systems with Java and Spring Boot, including a student information system used by nine Colombian institutions. My work spans data integrity, identity and access, reporting, production diagnosis, delivery, and the frontend work needed to ship complete solutions. I also write technical articles and notes about Java, Spring, security, and backend engineering.
