What I'm looking for

I work best with full ownership of an AI feature, from the first paper and prototype through evaluation, production deployment, and ongoing improvement.

I'm co-founding Vinder, where I build an agentic LLM system for conversational product discovery in e-commerce. I design multi-agent orchestration, tool calling, retrieval-augmented generation, and evaluation and ML CI/CD pipelines that make model changes measurable and trustworthy.

Previously, I spent six years at Contexta360 leading transformer-based NLP systems for enterprise conversational analytics, from research and fine-tuning to Flask microservices in production. My Ph.D. in machine translation and research across neural machine translation, graph neural networks, and distributed training ground my work in taking AI features from the first paper to deployed service.
