With over 3.5 years of experience, I have successfully developed E-NACH and UPI mandate systems from scratch, enabling auto-debit for 20,000+ monthly subscription renewals with a 100% success rate. I have also integrated Juspay and Razorpay into the payment system, supporting over 200,000 transactions per month and improving transaction reliability by 95%. Additionally, I have optimized and revamped dashboard APIs by migrating data from MongoDB to Elasticsearch, reducing response time by 50%. Prior to joining Onsurity, I worked as a Software Engineer at Kool Kanya and BidOnHomes, where I gained valuable experience in backend development, bug resolution, and system architecture optimization. I hold a Bachelor of Technology degree in Computer Science from Dr. A.P.J. Abdul Kalam Technical University. I am passionate about delivering high-quality software solutions that enhance user experience and business efficiency.
