At Amazon, I build scalable microservices and rate-vending APIs for Ship With Amazon, expanding shipping capabilities for third-party vendors. I own contract proposal lifecycles, real-time rate retrieval, and automated revenue and margin calculations.

I shipped a metadata-driven dynamic pricing configuration engine for Amazon Shipping, covering previously unhandled weight slabs and unlocking $15M in annual shipping potential. I owned the backend Java microservices, AWS CDK infrastructure, and React frontend end to end.

Previously at TheAyurveda Experience, I built an ad attribution platform processing behavioral events from 50M+ monthly users across 20 markets. I also developed inventory and order management systems using event sourcing, warehouse integrations, and Redpanda event pipelines.

I enjoy building reliable systems across Java, Node.js, React, AWS, and event-driven architecture, from product workflows to automated delivery pipelines. I've also deployed an AI-powered Ayurveda chatbot backend using Gemini and GPT APIs, increasing engagement by about 40%.
