What I'm looking for

I’m looking for a role where I can lead end-to-end, latency-sensitive AI systems—real-time voice, retrieval, and agent orchestration—with measurable gains in accuracy, latency, and governance, partnering closely with researchers and product teams.

I’m a Senior Software Engineer & AI Engineer focused on building realtime AI voice systems, multimodal retrieval engines, and largescale fullstack platforms across healthcare, real estate, and enterprise AI.

I architect and ship latency-sensitive, production-grade AI end-to-end: audio ingestion, multimodal embeddings, RAG pipelines, vector search, LLM-powered agents, and distributed inference—so systems perform under strict real-time constraints.

In recent roles, I’ve led streaming STT/TTS pipelines and agent orchestration (LangGraph/LlamaIndex), delivering sub-second transcription and response generation. I also optimize FAISS/pgvector retrieval, GPU/CPU inference (ONNX, quantization, Triton), and throughput/latency using robust evaluation and monitoring (drift detection and hallucination monitoring).

I value cross-functional collaboration with researchers, clinicians, and product teams. I build evaluation, observability, and governance frameworks (LangSmith, Langfuse, auditability) to improve accuracy, reduce hallucinations, and ensure reliable user experiences.
