I've developed and maintained enterprise-grade backend applications at Tecnotree Convergence Pvt. Ltd., supporting the Tecnotree Digital Convergent Billing System collection module.
I build Java and Spring Boot services, design RESTful APIs for billing and collection systems, and implement business logic and validation frameworks. I've also optimized SQL queries to improve database performance.
I investigate production issues through root-cause analysis, contribute unit tests, and participate in code reviews to support reliable releases.
I work in Agile/Scrum delivery environments and bring experience across microservices, MySQL, JPA, Hibernate, and production support.
