About Me
I’m a backend-focused Engineering Manager with 11+ years of experience architecting and scaling distributed systems across FinTech and HealthTech domains. I specialize in building reliable, high-throughput platforms that balance product velocity with long-term technical sustainability.
Currently, I lead engineering at Onsurity, driving platform reliability, scalability, and architectural governance across mission-critical HealthTech and Wellness systems. Previously at BharatPe, I led backend and mobile initiatives across lending and payments platforms, contributing to high-scale transactional systems and core financial products.
My work spans distributed backend architecture, performance engineering, observability, and cross-functional platform alignment. I’ve led modernization initiatives, introduced standardized engineering practices, reduced production incidents, and scaled teams during high-growth phases.
Technically, I work across Java, Spring Boot, Node.js, React, and modern cloud ecosystems, with a strong focus on scalable APIs, system resilience, and clean architectural boundaries. I’m passionate about building durable systems, mentoring engineers, and fostering a culture of ownership and operational excellence.
