About

Senior Software Engineer with 6.5+ years of experience building scalable, high-throughput systems across FinTech and Retail domains. My expertise spans backend engineering, distributed systems, and full stack development, with a strong focus on performance, reliability, and clean architecture. Currently, I work as a Lead Software Engineer at UST Global (Client: Walmart), where I modernize and optimize large-scale Order Management Systems. I design and enhance microservices, improve event-driven workflows across DB2, Cassandra, and MSSQL, and drive significant API performance gains through parallel processing and system optimization. Previously at HSBC, I contributed to mission-critical trading and IAM platforms, improving trade failure observability, reducing MTTR, and supporting backend migrations to GCP to enhance scalability and operational resilience. 🔹 Strengths & Impact • Reduced API latency by ~80%, significantly improving order reconciliation throughput • Improved MTTR by ~20% through real-time trade monitoring solutions • Designed and scaled microservices using Java, Spring Boot, and Kafka • Built and deployed cloud-native applications on GCP using Docker, Kubernetes & CI/CD • Contributed across the stack to deliver secure, performant, and user-focused solutions • Led legacy system consolidation into unified, maintainable architectures I enjoy solving complex engineering problems end-to-end — from system design and backend performance optimization to delivering reliable APIs and integrated front-end experiences. I’m currently open to Senior Backend or Full Stack Engineering opportunities where I can contribute to scalable, high-impact systems.
