Work experience

Principal Software Engineer at Walmart Global Tech, May 2024 - Present · 2 yrs 4 mos, Bengaluru, Karnataka, India, I’m a technology leader specializing in 𝐝𝐚𝐭𝐚-𝐝𝐫𝐢𝐯𝐞𝐧 𝐩𝐞𝐫𝐬𝐨𝐧𝐚𝐥𝐢𝐳𝐚𝐭𝐢𝐨𝐧 𝐬𝐲𝐬𝐭𝐞𝐦𝐬 that combine software engineering, data science, and large-scale architecture to create intelligent, customer-centric experiences. Within the 𝐏𝐞𝐫𝐬𝐨𝐧𝐚𝐥𝐢𝐳𝐚𝐭𝐢𝐨𝐧 𝐭𝐞𝐚𝐦, I lead initiatives that optimize fulfillment, streamline operations, and enhance decision-making through scalable engineering and ML-driven insights. 𝐒𝐦𝐚𝐫𝐭 𝐒𝐮𝐛𝐬𝐭𝐢𝐭𝐮𝐭𝐢𝐨𝐧𝐬 is one of the key systems I’ve designed—an intelligent substitution engine that recommends optimal alternatives when ordered items are unavailable. Built as a multi-constrained optimization problem, it considers customer preferences, pricing, and basket context to deliver precise recommendations. The solution is deployed across U.S. stores, improving fulfillment accuracy and operational efficiency. Expanding this concept, I led 𝐂𝐮𝐬𝐭𝐨𝐦𝐞𝐫 𝐂𝐡𝐨𝐢𝐜𝐞, extending personalization from post-transaction to pre-transaction. This enables customers to set substitution preferences during order creation, ensuring their online intent translates seamlessly into offline fulfillment. Another innovation, the 𝐔𝐧𝐢𝐟𝐢𝐞𝐝 𝐁𝐚𝐝𝐠𝐢𝐧𝐠 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 (𝐔𝐁𝐒), delivers a dynamic badging experience by ranking and optimizing product badges based on behavioral signals and historical interactions. It helps customers make quicker, more informed choices while improving engagement. My core responsibilities include architecting distributed systems, authoring design blueprints, and defining long-term technical roadmaps. I mentor senior engineers, drive automation across CI/CD pipelines, integrate telemetry and observability, and ensure adherence to modern design patterns and coding excellence. I’m passionate about building reliable, data-intensive systems that bridge personalization science with engineering precision—turning complex algorithms into scalable, production-grade customer experiences.
