At VISA Inc, I build deployment and storage platforms that remove manual operational work. I automated application deployments from repository to VM in Python, reducing a 20-minute manual process to 3–4 minutes.
I designed a privilege-separated daemon architecture, persistence and isolation controls, and convention-driven configuration generation. I also shipped an S3-backed file storage service with PostgreSQL metadata for thousands of weekly test artifacts across three global teams.
I build full-stack systems with Python, Java, Spring Boot, React, PostgreSQL, MongoDB, Docker, and AWS S3. My booking management project handles role-based workflows, payment consistency, idempotent webhooks, refunds, and validated booking state transitions.
