ML engineer and technical lead with 10+ years building production ML systems at scale. Deployed LLMs, semantic search, and foundation models serving 50M+ monthly queries and driving $100M+ in measurable revenue. Deep hands-on experience across the full ML lifecycle: model training, fine-tuning, optimization, serving, and monitoring.
- Foundation model: Domain-specific model encoding behavioral sequences for predictive and personalized applications across a $150B+ retail ecosystem
- Semantic search at scale: End-to-end system serving 50M+ monthly queries at P99 <200ms; +5% conversion lift over heuristic baselines, $108M+ attributable revenue
- FoodieLlama: Fine-tuned and quantized SLM for multi-intent query understanding, with safety evaluation, red-teaming, and deployment via Triton + vLLM (OpenAI-compatible API)
