About

Focused on backend quality, reliability, and maintainable delivery

Engineering backend systems that stay stable under scale, observable in production, and easy for teams to evolve.

Backend First Reliability by Design Maintainable Delivery

Who I am

I transitioned from Civil Engineering to Software Engineering and built my career around Java-based backend development. I enjoy solving production problems, improving maintainability, and shipping clean APIs that teams can trust.

My work includes service development, batch processing, quality automation, and API lifecycle practices across enterprise systems.

Current focus

  • Spring Boot microservices and scalable API design
  • SQL-first problem solving and data-heavy workflows
  • Testing with JUnit and Mockito
  • CI/CD and release reliability using Jenkins
  • Quality governance with SonarQube and Swagger docs
