Background

I'm a Java backend engineer who builds systems that hold up under pressure — healthcare data pipelines, large-scale CI/CD workflows, and enterprise Java migrations. I care deeply about correctness, performance, and clean design that the next engineer won't curse.

Currently a Senior Analyst at Accenture (Bangalore), where I own end-to-end Java modernization projects and production deployments. Before that, I spent three years at Infosys building secure, HIPAA-compliant integrations with Epic and Cerner for the Helix healthcare platform.

I graduated with a B.Tech from Guru Gobind Singh Indraprastha University (2017–2021) and have earned certifications from Infosys and Microsoft since joining the industry.
