Background
About Me
Results-driven Senior Backend Engineer with nearly 8 years of expertise in designing and deploying cloud-native applications using microservices architecture. Currently leading backend engineering at an Indian Private bank, specializing in developing resilient distributed systems and modernizing legacy architectures. Proficient in Java, Spring Boot, and enterprise-grade observability.
Experience
Senior Manager — Backend Engineering
an Indian Private bank
July 2025 – Present · Mumbai, India
Spearheading development of distributed microservices and leading Proof of Concepts (POCs) for innovative banking solutions at one of India's largest private banks.
- ▸Architected a custom Resilience & Utility Library to standardize cross-cutting concerns, resolving stability issues across multiple microservices.
- ▸Implemented automated Database Warmup routines to initialize connection pools, effectively eliminating cold-start latency.
- ▸Integrated configurable retry mechanisms and exponential backoff strategies to enhance fault tolerance across services.
Technical Lead
an Autonomous Society of MeitY, GOI Mumbai
March 2018 – June 2025 · Mumbai, India
Led a team of engineers modernizing monolithic government and enterprise systems, migrating to cloud-native microservices architecture on Kubernetes over 7+ years.
- ▸Led the modernization of monolithic systems by migrating to microservices architecture deployed on Kubernetes, improving scalability and deployment velocity.
- ▸Containerized applications using Docker and orchestrated deployments to accelerate delivery cycles.
- ▸Implemented robust CI/CD pipelines with Jenkins and Git, integrating DevOps best practices to streamline delivery.
