At Toss Solutions, I built 17 Flask REST API endpoints for EnsureKar, an accounting and tax-compliance platform, and deployed them to AWS EC2. I also integrated CCAvenue across a four-stage payment flow, using AES-128-CBC encryption and confirming payment success before marking orders paid.
On Kaksha, I reduced satellite collision screening time by computing each orbit once and filtering impossible pairs. I’ve also built an AI interview practice platform with a RAG pipeline and a sign-language recognition platform that reached about 83% accuracy across 290 sign classes.
