Vikas Chaurasia

AI/ML Engineer · GenAI Application Developer

I design, build, and deploy GenAI systems that turn domain knowledge into reliable, production-ready decision support.

With an MSc in Data Science & Business Analytics, I combine SQL, Python, ETL workflows, and business-facing analytics to design reliable data products, and ship GenAI + ML systems that deliver measurable outcomes.

// What I Deliver

  • ▶ RAG pipelines that retrieve and reason over domain-specific documents
  • ▶ Multi-agent systems with LangGraph for complex, multi-step business workflows
  • ▶ Production ML APIs (FastAPI + Docker) with experiment tracking via MLflow
  • ▶ GenAI applications that non-technical stakeholders can actually use

// My Approach

  • 🧠 Start from the business problem — then pick the right model/architecture
  • ⚡ Build for production from day one — not just a working notebook
  • 📊 Evaluate rigorously — calibration, drift monitoring, benchmark metrics
  • 🚀 Ship it — live deployments, not just GitHub repos
