Tanmoy S.

I build AI systems that hold up in production, not just convincing demos: AI-agent workflows, RAG and document intelligence, and the full-stack SaaS products around them. Current work: - Co-Founder & Head of Technology and AI at Quiet Engine, an AI-native GTM platform that turns product context into multi-agent outbound missions across email, LinkedIn, and calls. - Founder & CTO at ChitraYantra Technologies, building institutional AI platforms in production: a NEP 2020 University ERP with Academic Bank of Credits and DigiLocker-verified credentials; Educator, which runs faculty-locked conversational AI vivas with spoken-reasoning scores for 1,000+ students simultaneously; a markerless sports biomechanics engine that turns ordinary 4K/120fps video into Newton-Euler inverse dynamics and OpenSim datasets across 10+ disciplines; a sovereign tri-lingual digitization platform (English, Bengali, Hindi OCR with sub-2-second semantic search, 100% on-premise in India); Sahakar, a blockchain-anchored cooperative operating platform with automated DCCB, SCB and NABARD reporting; and a portable ABDM-ready tele-triage platform with AI image-to-data capture and doctor-led follow-up. - Founder of EvidenceHire, an adaptive AI interview engine for evidence-based candidate verification and syllabus-grounded placement interview practice. My work covers: - AI agents and multi-agent orchestration (OpenAI, Claude, and Google agent SDKs, LangChain) - RAG, document ingestion, OCR and structured extraction, search, citations, and evaluation - Full-stack AI SaaS with Next.js, React, TypeScript, Python, Node.js, PostgreSQL, and cloud deployment I bring 15 years of software engineering experience and a postgraduate AI degree from IIT Guwahati to scope the real workflow first and choose the smallest reliable solution. I am Top Rated with 100% Job Success, $100K+ earned, 166 completed jobs, and 2,318 hours on Upwork. If you need an AI feature, internal copilot, document workflow, or full product built with sound engineering judgment, I can take it from architecture through production.
