About

As Engineering Manager for rYde at redBus, I owned the end-to-end technology for the cab and bus rental platform. I led the design and delivery of core backend systems, including partner API integrations, an in-house GDS, an event-driven orchestration system, admin and operational tooling, and cron/scheduler services. I also owned the B2C web and mobile applications and their integrations with payments, notifications, and OMS. A key individual contribution was building a real-time pricing engine using polygon-based mapping for accurate distance and fare calculation. Additionally, I delivered franchisee software and contributed to driver and operator mobile apps, enabling rYde to scale supply, improve reliability, and reduce operational overhead.

I owned the end-to-end mobile re-architecture of the redBus app, leading a large-scale transformation across both frontend and backend systems. This began with the re-architecture of the redBus mobile application, encompassing the homepage, search and booking flows, and payment journeys. I led the effort across the full stack, aligning frontend experiences with scalable backend services.
On the backend, I drove significant service optimizations, improving system latency and performance at peak scale. I also led critical database migrations to support higher throughput and reliability.

Senior Software Engineer

Nov 2015 – Jan 2020 · 4 yrs 2 mos · Bengaluru Area, India

I led multiple high-impact initiatives and served as the technical engineering lead for the Bus and Flight verticals, driving end-to-end delivery and successfully launching these businesses for millions of customers.
I played a key role in shaping Paytm’s super-app experience by leading the design and development of the homepage platform, enabling multiple product journeys to coexist seamlessly at scale. At the time, Paytm served the largest user base in India, and I was responsible for building systems capable of handling extreme traffic and reliability demands.
In parallel, I contributed to the growth of Paytm Payments by leading merchant integrations and strengthening the payment platform’s scalability and resilience. Overall, my work focused on building foundational systems, leading teams across critical verticals, and delivering reliable, high-scale products for one of India’s largest digital platforms.
