Sayan Debnath

I’m a Software Engineer with 2+ years building production-grade AI and web systems, specializing in React and Python (FastAPI). I focus on end-to-end delivery—turning ideas into reliable microservices, fast APIs, and user-facing dashboards.

At Smarter Codes, I designed and implemented an AI research engine using Python (FastAPI) and vector similarity search, reducing document retrieval time by ∼40% across large corpora. I also maintained 5+ critical backend microservices with Docker and Kubernetes, supporting ∼99.9% uptime and seamless scaling.

I’ve built products that make AI operational: I developed 3+ React-based dashboards to monitor AI-driven document processing workflows, enabling real-time tracking of 60+ document processing events per day. Previously at Cogzin Technologies, I improved system integration by reducing data sync errors by ∼30% and improving response processing time by ∼20%, while orchestrating CI with Jenkins to shorten feedback loops by ∼20%.

My projects reflect the same drive: in DocMind AI, I built an AI document intelligence platform with citation-backed RAG and agentic extraction workflows, reducing document search and analysis time by ∼60%. I’ve also built a Website Search Engine that improved search relevance and cut manual lookups by ∼70%, and an AI Amazon Listing Generator that reduced listing creation time by ∼80%.
