About

Backend Software Engineer building Java services on the iMAL Core Banking platform, a high-volume, mission-critical financial transaction processing system. Experienced across the full backend stack: Spring Boot, Hibernate/JPA, REST and microservice APIs, Kafka event streaming, and relational (MySQL, PostgreSQL, Oracle) and NoSQL (Redis) data stores. Comfortable with concurrency and distributed systems, having built a Kafka/Redis-based microservice that processes high-throughput financial transactions, designed to handle concurrent balance updates safely. Track record of root-causing production defects and tuning SQL for transactional workloads at scale, cutting query execution time by ~30%. Solid grounding in OOP, SOLID principles, and design patterns, with a strong interest in writing correct, maintainable code for reliability-critical systems.
