What I'm looking for

I'm looking to build production AI products and infrastructure where agent systems, RAG, machine learning, and cloud platforms create measurable customer and business impact.

At Optimizely, I engineer the agent execution engine behind Opal, enabling marketing and digital teams to build and run AI agents without code. I’ve also launched a shared RAG layer serving around 40K grounded, source-backed answers daily across nine product teams.

I build practical AI infrastructure end to end: tool registries, prompt routing, episodic memory, LLM evaluation, and contextual-bandit recommendation systems. My work has supported hundreds of customers, reduced audience segment creation time by around 95%, and automated training for thousands of models each day.

Previously, I delivered NLP, computer vision, OCR, classification, and recommendation systems across e-commerce, industrial automation, and autonomous-driving use cases. I work primarily with Python, cloud platforms, and production ML tooling, and I share what I learn through 60+ technical articles.
