About

I'm a Lead Full-Stack Engineer with a Master's in Computer Applications from NIT Tiruchirappalli — one of India's premier technical institutes. My academic foundation in distributed systems and algorithms sparked a passion for building platforms that scale, and that curiosity has driven every step of my career since. Over the past 5+ years at BNY, one of the world's largest financial institutions, I've designed and delivered cloud-native systems processing 1M+ records monthly across 10K+ client operations. I specialize in Java, Spring Boot, Microservices, Angular, and GenAI automation — working across the full stack from architecture design to production deployment. Some highlights I'm proud of: → Modernized legacy VB6 systems into Java microservices using GenAI, cutting migration effort by 85% → Architected 5+ distributed components, reducing production incidents by 30% → Built 100+ secure REST APIs with OAuth2 and JWT for enterprise financial workflows → Automated email processing pipelines reducing manual effort by 90% → Established CI/CD pipelines cutting post-release defects by 80% → Recognized with the BNY Passion for Excellence Award for optimizing statement processing workflows Beyond code, I actively mentor junior engineers, lead architecture discussions, and champion clean code, TDD, and high-quality delivery practices across teams. I believe great engineering is as much about people and communication as it is about technology. Looking ahead, I'm excited about roles focused on system modernization, distributed architecture, and leveraging GenAI to solve real enterprise challenges at scale. I thrive in environments where engineering excellence and business impact go hand in hand. 📩 Open to senior/lead opportunities in backend or full-stack engineering.
