About

Results-driven Software Development Engineer with 6+ years of experience designing and scaling platforms in fintech, payments, and data systems. I thrive at the intersection of deep technical problem-solving and strategic leadership, building platforms that process millions of daily transactions with high reliability and cost efficiency. At Navi and Flipkart, I’ve led engineering teams to deliver scalable rewards ecosystems, high-performance financial systems, and data-driven collections platforms that improved efficiency, reduced costs, and drove measurable business growth. My work has directly contributed to 25x UPI market share growth, 99.97% application uptime, and significant reductions in cloud and infra spend. I bring a strong foundation in distributed systems, paired with a track record of mentoring teams, driving operational excellence, and aligning technology with business goals. Passionate about system scalability, developer productivity, and operational excellence, I enjoy tackling complex engineering challenges and turning them into opportunities for growth, efficiency, and impact.

At Navi, I lead the engineering efforts behind our rewards, referrals, and wallet ecosystem — a critical platform driving user growth and engagement. I’ve scaled the system to support millions of daily UPI transactions, while reducing infrastructure costs and improving reliability.
Contributed to Navi’s UPI growth journey, scaling platforms that enabled a 25x market share increase and secured its position as India’s 4th largest player
Re-architected systems to handle 57x traffic (benchmarked to 50k RPS reads and 10k RPS writes) at 40% lower cost, while driving faster campaign rollouts (weeks → hours)
Boosted system uptime from 99.2% to 99.97% through proactive monitoring and resilient design.
Collaborated closely with product teams to launch campaigns faster — cutting time-to-market from weeks to hours.
Stabilized low-latency communications layer (MQTT-based) offering at Navi that replaced inefficient polling with reliable message delivery, improving engagement and supporting 300K concurrent connections.

At Flipkart, I worked on re-architecting core financial systems that powered large-scale e-commerce financial operations, ensuring reliability, modularity, and the ability to support rapidly evolving business requirements. My focus was on building high-performance, asynchronous processing backends capable of handling massive transaction volumes with speed and accuracy.
Contributed to the re-architecture of legacy accounting platforms into modular, pluggable backends, creating a flexible architecture that made it significantly easier to onboard new business flows without heavy engineering overhead.
Built asynchronous financial processing systems leveraging Storm for distributed, high-throughput event processing and Java CompletableFuture for non-blocking execution, enabling parallelism and reduced latency in transaction pipelines.
Designed and implemented generic contracts and extensible APIs, ensuring that different financial services could be integrated seamlessly with minimal duplication.
