What I'm looking for

I seek senior engineering roles where I can lead backend and cloud initiatives, design scalable microservices, and mentor teams while working on data-driven, observable production systems.

I am a results-driven software engineer with over a decade of experience building large-scale Java-based systems, cloud migrations, and event-driven platforms. My work spans enterprise-grade microservices, data pipelines, and resilient backend services.

At Canterr India I led development of an operational MDM platform, built Kafka->Pub/Sub ingestion pipelines, and designed an AI-powered chatbot using Java and Spring Boot with embedding-based retrieval for production deployment.

I have architected and executed on-prem to Google Cloud migrations, designed secure microservices for transaction-heavy systems, and implemented high-performance Java modules with resilience and distributed caching patterns.

My background includes engineering event-driven royalty services, creating automation and migration tools (Spark, Spring Boot), and maintaining high test coverage and observability across systems. I prioritize scalable design, measurable reliability, and pragmatic engineering practices.
