I am a Software Engineer with over 4.5 years of hands-on experience architecting high-throughput backend systems, scaling microservices, and building enterprise-grade SaaS features. My track record at Kissflow highlights my ability to solve complex technical bottlenecks—from re-engineering audit data pipelines with Apache Kafka to handle over 300,000 daily events without data loss. Whether it’s building full OAuth 2.0 Identity Provider flows from scratch, optimizing multi-threaded background processing engines, or integrating AI feature management platforms.
