About

I’m a backend-focused full-stack engineer working with Spring Boot and Angular, building systems where correctness and reliability matter. Currently contributing to Apache Fineract, an open-source core banking platform used for financial inclusion. My work focuses on transaction safety, idempotency design, CI/CD hardening, and improving database migration reliability across PostgreSQL and MariaDB environments. At Muthu Soft Labs, I build and maintain production applications using: •Spring Boot: Service-layer design, REST APIs, and transactional logic. •Angular + RxJS: Predictable state management and reactive UI architecture. •PostgreSQL: Query optimization and schema evolution. •Clean Architecture: Applying SOLID principles and modular design. I care deeply about: •Transaction integrity in distributed systems. •Eliminating duplicate financial operations. •Reducing technical debt through better state design. •Writing code that survives production. I’m continuously learning by building, contributing, and reviewing real-world systems — not just tutorials.
