About

I design and operate distributed backend systems built for high throughput, low latency, and production resilience. At NatWest Group, I build the microservice infrastructure that sits on the live transaction path of banking operations — event-driven pipelines, real-time APIs, and cloud-native services that have contributed to preventing $12.5B in potential fraud losses in FY2024. My work spans the full platform depth: Kafka-based event streaming, APIGEE-governed REST APIs, MongoDB data modelling for high-volume audit and compliance workloads, and cloud-native deployment on Kubernetes and PCF with GitLab CI/CD. I focus on the engineering problems that matter at scale: service reliability under load, fault tolerance, observability, and low-latency system design. I've built end-to-end observability stacks with Splunk and DXAPM that cut incident response times by 30%, and I own services from API contract through production monitoring — including incident response and performance optimisation.

Previously at Axtria, I built Spring Boot integration services for enterprise data platforms in life sciences analytics. M.Tech from IIIT Bangalore · AWS Solutions Architect (Associate). Open to senior backend engineering roles building high-scale platforms — payments infrastructure, booking systems, marketplace backends, or financial data pipelines where reliability and throughput are first-class engineering concerns.
