Rupak Das

I’m a Senior Software Engineer who thrives on building production-grade systems end-to-end, from architecture to delivery. I’ve earned recognition as a 2-time Hackathon Winner, with solutions valued for technical innovation and real-world applicability.

I’m an AI-Native Engineer actively building with LLMs in production. Using Claude Code, I’ve co-authored system architecture specs and accelerated complex API development across Kronos, SwitchStar, and SAM-Spine—covering agentic spec generation, architecture design, and LLM-assisted development workflows.

On SAM-Spine, I built key components like Kronos workflows, ETL pipelines into the SPINE PostgreSQL evidence store, and an LLM-powered transcript analyzer for dual-factor behavioral construct scores. I also engineered SwitchStar with AI-assisted workflows for content classification and automated decision routing, plus a real-time streaming platform using WebRTC/PeerJS and cloud-native GCP pipelines.

Beyond AI, I’ve shipped performance wins across analytics and consumer experiences—re-engineering an audience hierarchy system for faster load times, building a healthcare analytics dashboard for 100K+ users, and delivering high-performance C# services that reduced screenshot capture time by 85%. Earlier, I delivered full-stack ASP.NET MVC products like a Pharmacy Management System and Vimopay B2B recharge platform, always grounded in Agile/Scrum, code reviews, and unit testing.
