Key Contributions: SBI client office deployment: Deployed at SBI’s Navi Mumbai client office, where I was responsible for end-to-end production support, feature deployment, and issue resolution for critical fintech applications. Worked closely with the SBI technical and business teams to understand requirements, troubleshoot production issues, and ensure smooth delivery of new features. RBL OAuth Integration: Developed and implemented OAuth-based authentication for RBL, enabling secure API access via token-based authorization. This integration was vital in establishing secure and seamless communication between systems. LogosAPI Using S3 CDN: Designed and delivered a scalable API service to provide high-performance, low-latency logo URLs via AWS S3 CDN. This ensured consistent content delivery across client-facing platforms. CBS SSO Integration for SBI: Contributed to the integration of CBS Single Sign-On (SSO) for SBI clients, enhancing user experience by providing secure and streamlined access to the FinPro portal. Sentinel Token Implementation for RBL: Implemented Sentinel token management for RBL integrations, ensuring critical header-based security and reliable inter-system communication. Led integrations with third-party services such as Experian and Advarisk. Metrics Dashboard Backend for TSP: Developed the backend infrastructure for a metrics dashboard, providing TSPs with detailed analytics on consent success rates, data retrieval statuses, and operational metrics for better decision-making. Client Engagements: Successfully collaborated on projects and integrations for key clients, including State Bank of India (SBI), RBL Bank, Ujjivan Small Finance Bank, JFS, and Lendingkart, contributing to smooth onboarding, solution delivery, and ongoing support debugging and root cause analysis.

About

As a Software Engineer, I specialize in building secure, scalable, and high-performance fintech solutions. With hands-on experience at OneMoney and a solid foundation from TCS, I am proficient in Java, Spring Boot,and Node.js with Express.js, designing and developing RESTful APIs and cloud-native applications. I have a proven track record of implementing microservices architectures, integrating third-party services, and managing secure OAuth2-based authentication systems. Experienced in backend technologies, cloud platforms like AWS, and containerized deployments using Docker and Kubernetes, I thrive in fast-paced, Agile environments and focus on delivering client-centric solutions that adhere to high-quality, regulatory-compliant standards.
