What I'm looking for

I'm looking to build reliable backend systems, REST APIs, and database integrations while growing through collaborative Agile delivery, code reviews, testing, and challenging engineering work.

I've built and maintained backend services for banking and CRM applications at Andersen Lab, delivering REST APIs for customer operations, recruitment workflows, application tracking, status management, and reporting.

I troubleshoot integration and processing issues, implement validation, error handling, and structured logging, and optimize PostgreSQL queries to resolve redundant joins and N+1 query problems. I also write unit and integration tests and collaborate with QA and business analysts through iterative feature refinement.

My stack includes Java, Spring Boot, PostgreSQL, Docker, Kafka, Redis, and AWS. I also built a UNIX shell and backend systems using message brokers and caching, with a focus on reliable, maintainable services.
