Product challenge
Walmart India HR needed one reliable product for campus engagement across major colleges: events, AMAs, quizzes, rewards, placement activity, and the operational visibility behind them. As the sole developer, I needed to translate stakeholder needs into a feasible product, cost it, build it, pass enterprise controls, and operate it in production.
Product and engineering approach
Shape the product around the operating team
- Designed workflows for real-time events and hackathons, AMA and Q&A sessions, quizzes and leaderboards, and a point-based reward store.
- Built an admin product for event management, student analytics, resource use, and system load so HR could run the platform without engineering intervention for routine work.
Own the complete implementation
- Built the user and admin experiences with React and TypeScript, mobile applications for iOS and Android, and backend services with Express.js, PostgreSQL, and Redis.
- Designed for more than 3,000 concurrent users and a total audience of about 375,000 students.
- Produced compute, storage, network, scaling, and cost estimates so technical architecture could be evaluated as a business decision.
- Took the containerized product through Walmart Cloud Native Platform certification, service-mesh deployment, and security and compliance review.
Outcome
- Delivered the platform end to end as a single hands-on owner, from product shaping and interface design through deployment and maintenance.
- Supported a potential audience of 375,000 students and more than 3,000 concurrent users in Walmart’s production environment.
- Passed WCNP certification plus internal security and compliance reviews.
- Reduced manual coordination for campus engagement and gave HR clearer control over events, participation, and platform operations.
- Connected scope, infrastructure, and cost planning early enough to avoid treating production economics as a post-launch concern.
