About

With expertise in building and optimizing high-performance systems using Golang, Kubernetes and Blockchain, I have enhanced Backend systems from handling 1-2 million requests/second to onboarding 1000s of Walmart stores and grocery DCs. Solved problems related to Kafka unidirectional limitations through gRPC, rebalancing issues and consumer lag through a proxy server. Also, implemented Kubernetes CPU milli-cores & ephemeral storage optimizations to reduce idle resource costs. In the FinTech sector, I developed a scalable Lending product, integrating with multiple NBFCs to launch Early Wage Access, Bullet Loans, and a custom credit-scoring framework disbursing over ₹1250 Million in 8 Months. Published IEEE research on blockchain and developed "An Interoperable & Secure E-Wallet Architecture Based on Digital Ledger Technology." Key Strengths: Golang, Python, Java, Web3, Microservices Architecture, gRPC, CI/CD, Kafka, Blockchain (Solidity, IPFS), Kubernetes, Cloud DevOps (AWS, GCP), High-Performance Data Processing, Scalable Backend Systems.

Led the development of a Lending product along with authentication that successfully disbursed over ₹1250 Million within 8 months. This role required not only deep technical knowledge but also an ability to build resilient and secure financial systems within Government regulations. By integrating multiple NBFCs and delivering Early Wage Access(EWA), Multi EMI and Bullet Loan products, I was able to significantly enhance financial access for blue-collar workers.
