Software Engineer

LTIMindtree · Jan 2025 – Present

Not yet confirmed
  • Client Project:
  • Architected and shipped a high-throughput transaction monitoring & reconciliation platform (Java · Spring Boot · Hibernate/JPA · MySQL) processing 100K+ daily transactions at <200ms p99 latency with idempotent write guarantees and ACID compliance — running live for HSBC's enterprise banking operations.
  • Led migration of legacy batch pipeline to Apache Kafka event-streaming architecture — partitioned topics, consumer groups, dead-letter queues (DLQ) for fault-tolerant recovery, and eventual-consistency decoupling between ingestion and reconciliation — improving system throughput by 60%.
  • Optimised Hibernate/JPA queries and MySQL indexes achieving 3x faster transaction resolution; eliminated race conditions via optimistic locking; enforced connection pooling for high-concurrency stability.
  • Built stateless JWT + Spring Security RBAC auth layer with role-scoped API access, token validation, and secure inter-service communication for enterprise banking compliance.
  • Achieved 80%+ test coverage on all critical paths using JUnit 5 + Mockito; enforced PR review standards and CI/CD gating via GitHub Actions pipeline.
  • iTracker — Internal Workflow Automation
  • Designed and shipped iTracker — a full-stack workflow automation tool (Angular + Spring Boot REST APIs + MySQL) for 50+ internal users — replaced manual Excel-based tracking with automated approval pipelines, cutting manual effort by 90%.
  • Implemented 3-tier RBAC approval flow (Submitter → Reviewer → Admin) with state-transition guards and automated email notifications — zero-defect production launch, still in active use.

  • Built a full-stack transaction monitoring platform (Spring Boot + Angular) processing 100K+ daily transactions at sub-200ms p99 latency, with idempotent write guarantees and JWT-based role-based access control.
  • Migrated a legacy batch pipeline to Apache Kafka event streaming, improving throughput by 60%; implemented dead-letter queues for failed-message recovery and decoupled ingestion from reconciliation via eventual consistency.
  • Optimized Hibernate/JPA queries and database indexes, achieving 3x faster transaction resolution; eliminated race conditions using optimistic locking on high-concurrency write paths.
  • Designed and shipped iTracker, an internal workflow automation tool (Angular + Spring Boot REST APIs) used by 50+ employees, replacing manual Excel-based tracking with a 3-tier approval pipeline and cutting manual effort by 90%.
