What I'm looking for

I’m looking for a Generative AI engineering role where I can build production data and ML solutions, including RAG pipelines, agentic workflows, and MCP tooling.

At Chryselys, I work on production Generative AI systems for UnitedHealth Group and Novartis. For UnitedHealth Group’s Auto-Audit, I refactored the batch pipeline to combine a deterministic pre-check with an LLM adjudication chain, cutting processing time from 38 hours to 6.

I was the sole developer of CS-HUB, a pharmacy comment quality and compliance platform. I built its asynchronous worker-queue ETL and multi-pass Google GenAI scoring, reducing runtime from about 120 hours to under one hour.

For Script Engine TC, I built MCP tools with guardrails that let teams query pharmacy data in plain English while blocking destructive SQL operations. For Novartis’s Zolgensma Pod, I developed a centralized feedback feature and worked on data processing and information extraction across diverse datasets.

Before Chryselys, I worked on real estate, cybersecurity, fitness, financial, and internal CRM products. At StepSetGo, I worked on event-driven microservices serving 10M+ users and resolved more than 150 bugs in the achievement services. My work spans Python, TypeScript, distributed systems, and production data and ML solutions.
