Saptak Dutta

I’m a Software Engineer focused on building products that solve real-world problems and create meaningful impact. I develop full-stack applications, scalable backend systems, and automation-driven solutions, with a strong product mindset from idea to deployment.

In my projects, I architected an AI-powered knowledge management platform that turns any URL into actionable summaries. I built secure authentication and authorization with JWT and bcrypt, integrated LLMs via the Groq SDK for low-latency inference, and engineered automated extraction pipelines using Puppeteer and yt-dlp-wrap to process YouTube transcripts for AI analysis.

I also developed production-ready backend systems, including a video streaming platform with Cloudinary media pipelines, JWT-based security with role-based access control, and MongoDB aggregation for large-scale filtering and pagination. Alongside that, I built a full-stack hotel booking platform with LocationIQ and Leaflet for interactive map-based discovery, using a scalable MVC architecture and centralized error handling to keep reliability high.
