What I'm looking for

I'm looking to build and ship production AI products, especially RAG, agentic systems, and cloud-native ML platforms that create measurable business impact.

At AstraZeneca, I architect production RAG and agentic AI systems for regulated document repositories, cutting search time by 90% and enabling traceable, fully grounded responses at scale. I also evaluated LLaMA, Phi-3, and Claude for HCP insights and built deployment pipelines supporting real-time decision-making.

I've shipped enterprise AI products across Azure, AWS, GCP, and Snowflake, including a Freedom Mortgage RAG chatbot projected to generate $5.28M in annual productivity gains and a VoiceLink restaurant automation platform with sub-two-second latency and a 95% call success rate. Earlier, I built collection optimization models at John Deere Financial and improved Samsung Bixby voice-AI experiences through NLP and reinforcement learning.
