Hi, I'm Koushik Vasa 👋

AI / ML Engineer · Full-Stack Developer · Building AI that ships.



🧠 About Me

I'm an AI/ML Engineer & Full-Stack Developer with an MS in CS (Machine Learning) from George Mason University (GPA: 3.87). I don't just build models — I ship production AI systems that handle real users and real data.

  • 🔭 Currently building Bridgette, a production RAG pipeline at BridgeNow AI — matching users to domain experts at scale using LangChain + semantic vector search
  • 🤖 Specialties: RAG pipelines, LLM agents, multi-agent orchestration, AI-powered full-stack apps
  • 🧪 Obsessed with inference reliability, latency optimization, and measurable real-world impact
  • 📍 Based in New York, NY — available for full-time roles
