About Me

Backend engineering with scale, structure, and delivery focus

I’m a Mumbai-based software engineer with 10+ years of experience building enterprise applications, microservices, ETL systems, and APIs for teams in logistics, education, finance, healthcare, and banking.

My work centers on Java, Spring Boot, Python, Kafka, AWS, and clean architecture. I care about performance, maintainability, testability, and shipping systems that teams can trust in production.

Across recent roles, I’ve automated GIS data pipelines, integrated cloud messaging flows, migrated legacy systems, containerized services for AWS ECS, and built CI/CD pipelines with Terraform and GitLab.
