At Praetorian, I helped rebuild the vulnerability scanner from scratch with serverless technologies, including DynamoDB, AWS Lambda, and AWS SAM. I also scaled the scanning pipeline to handle 50 million events per day and reduced infrastructure usage by 50%.

At Razorpay, I developed backend systems for payments, including a tokenization engine for card-issuing banks. I also improved payment-service performance and built merchant dashboards that reduced support tickets.
