Software Engineer @ Bristol Myers Squibb | Backend & Distributed Systems | Python, Backend, Cloud Infrastructure

About

I'm a Software Engineer at Bristol Myers Squibb, interested in building reliable backend systems, distributed workflows, and data-intensive applications. My work spans backend development, cloud infrastructure, data pipelines, and AI-enabled systems. I enjoy tackling engineering problems where performance, reliability, and maintainability matter just as much as getting the feature to work. Previously, I worked at Bajaj Finserv Health, where I contributed to vision-based processing pipelines, deterministic medical nomenclature mapping, and API performance optimization. At Wipro, I worked on interactive 3D applications and containerized full-stack services. Outside work, I build projects that let me explore systems engineering in depth. Structurify explores serverless ETL workflows and data processing, while Quarantine is an open-source Python library for fault-tolerant dead-letter queue handling. I'm also a Hack4Bengal 3.0 first-prize winner, a LeetCode Knight, and a contributor to research on accessible, vision-based human-computer interaction. I enjoy discussing backend engineering, distributed systems, cloud architecture, developer tooling, and practical applications of AI. Outside work, I build projects that let me explore systems engineering and developer tooling: • Byakugan Scan: Native in-memory macOS screen OCR utility written in Swift. • Quarantine: Open-source Python library for fault-tolerant dead-letter queue handling. • Structurify: Serverless ETL workflows and data processing. I'm also a Hack4Bengal 3.0 first-prize winner, a LeetCode Knight, and a contributor to research on accessible, vision-based human-computer interaction.
