Dunzo

Head of Engineering

Aug 2019 – Jun 2020 · 10 mos

At Dunzo, I led the architectural transformation of the platform from a monolithic system to a scalable, microservices-based architecture using Python and Golang. This modernization effort resulted in a significant reduction in service downtime and significantly improved system scalability and maintainability. I architected real-time inventory synchronization solutions by integrating with major retail systems such as Apollo, BigBasket, and LimeTray, which dramatically reduced out-of-stock incidents. Additionally, I spearheaded the development of intelligent systems to optimize inventory management across dark stores, leading to a 30% improvement in order processing efficiency.
My work also included leveraging data-driven decision-making and predictive analytics to enhance operational performance. I oversaw the integration of Google Location APIs with predictive models to enable real-time tracking and accurate ETAs, improving delivery performance significantly. I implemented IoT-based weather monitoring solutions to drive dynamic surge pricing and automate responses to external conditions. I played a key role in launching a bike ride-sharing service by repurposing existing tracking systems, driving growth in DAU and MAU. Furthermore, I led the creation of a dynamic partner incentive system to ensure availability during peak times and collaborated with cross-functional leadership across product, operations, and data science. By establishing agile practices and mentoring a high-performing engineering team, I consistently delivered strategic, end-to-end technical solutions aligned with business goals.
