Led two high-impact engineering engagements for Fortune 500 companies. One was zero to one, the other was walk into a crisis, stabilise it, and then rebuild everything from the ground up. The first was a Perks & Rewards platform built from scratch for a Fortune 500 Fintech with a team of three. The platform grew faster than expected and we had to rethink the architecture mid-flight. Moved from monolith to microservices, rebuilt the data layer with an ETL pipeline keeping writes on SQL and reads on Elasticsearch. Partners could onboard in minutes, manage campaigns end to end, and get deep visibility into purchase behaviour, regional acquisition and funnel drop-off. Partners needing deeper integrations got SDKs for event-based triggers without redirecting user flows. Engineered for 99.9% SLA with security, compliance and multi region failover. Scaled to 1M daily active users and 100K concurrent requests at peak, delivering $100M+ GMV over two years. The second was harder in a different way. One of India's largest life insurers had a mission-critical platform that was bleeding — four hours of daily downtime and partner onboarding stretching into months. We stabilised it in three weeks before peak sales season. Then rebuilt the entire system while staying compatible with decades-old legacy ecosystem that couldn't be switched off overnight. The new platform was configurable by design, AI-powered workflows sped up launches and integrations, and moving away from expensive cloud dependencies to open-source alternatives that significantly reduced infrastructure costs. 100+ partners now connect to a central platform, change requests happen in hours instead of weeks and tech is no longer the bottleneck between business and delivery.

About

I'm deeply passionate about leveraging technology to build solutions that handle scale and complexity. Over the course of my software engineering journey, I've had the opportunity to architect platforms for Fortune 500 companies across consumer tech, insurtech, payments, and loyalty — serving millions of users, handling 100K+ concurrent requests, and delivering $100M+ in business value. I treat technology as a tool to solve business problems, not as an end in itself. Currently, I serve as a Tech Lead at Wednesday Solutions, a specialized engineering services company with a focus on Gen AI, Data Engineering and Application Modernization.
