What I'm looking for

I’m looking for AI engineering or full-stack roles where I can build production-grade GenAI—especially voice and RAG systems—with real-world product impact. I care about cost/latency discipline, measurable evals, and dependable deployment.

I build production-grade GenAI systems and full-stack products, with a focus on end-to-end evaluation, cost-aware safeguards, and real-time user experiences. I recently built and shipped a Voice AI agent with STT→LLM→TTS pipelines, GPT-4o with Deepgram STT and ElevenLabs TTS, achieving <1.5s end-to-end latency and >90% accuracy across 200+ calls.

I also engineer grounded RAG experiences that return source-cited answers over real documents. I created a Policy QA RAG pipeline using pdfplumber extraction, overlapping chunking, OpenAI embeddings, Elasticsearch dense vector indexing, and a FastAPI REST endpoint that returns structured, cited responses validated with Pydantic v2—containerized for reliable deployment.
