What I'm looking for

I’m looking to build AI/ML systems across GenAI, RAG, conversational AI, and computer vision that leave the lab and get used. I value complete, working systems tested with real users.

At Deliverail, I developed an AI-powered booking chatbot that integrates LLMs, Python, and REST APIs to streamline customer interactions and automate booking workflows. I also developed an administrative dashboard with backend integrations and SQL-based data management.

I built EMMA, an on-device voice receptionist deployed for Deliverail, that handles shipment bookings and delivery-status questions. It uses faster-whisper, a local Ollama LLM, and Coqui TTS, with validation and knowledge-grounding checks before the model responds.

I also built Kuro, an offline assistant that answers questions from users’ documents with cited responses, and CareerOS, a job-search platform that organizes applications and requires human approval for AI-suggested actions. I publish independent AI/ML projects as open-source GitHub repositories.
