I’m a Software Development Engineer at Juspay Technologies, where I focus on building reliable, high-performance backend systems for reconciliation and payments workflows. I optimize server performance by refactoring blocking code into async logic, leveraging OS-level threads to improve concurrency and eliminate timeouts.

I’ve developed core product capabilities including a process tracker for reconciliation, and a Rust-based scheduler (Kairos) that lets users schedule, edit, and manage one-time, recurring, and cron jobs through an intuitive dashboard. I also built a plug-and-play JWT-based authentication framework across APIs, replacing a legacy client ID/secret approach and improving API response times by 50–100 percent.

In fintech integrations, I led settlement API integration for PAYU, Razorpay, Tpsl, Cashfree, and Airwallex, automating reconciliation to reduce manual intervention, improve accuracy, and save substantial time. I also led the settlement module development (beneficiary storage, SID generation, settlement instruction generation, and payout approval) with major workflows enabled through a maker-checker framework, and strengthened data sanity via checks on backdated/historical records.
