What I'm looking for

I seek hands-on engineering roles building and scaling production Generative AI/LLM systems with strong MLOps, team mentoring, and a bias for shipping reliable, customer-focused solutions.

I am a builder with over a decade of hands-on experience designing, shipping, and scaling machine learning systems for production. I have led MLOps and ML engineering efforts at startups and mid-sized SaaS teams, delivered custom LLM solutions, and implemented robust CI/CD, serverless deployments, and evaluation frameworks to keep models reliable in production.

At scale I focus on practical outcomes: fine-tuning open-source models, deploying RAG systems with vector stores, and automating workflows via LangChain and prompt engineering tools. I move fast with Python, apply Go and Java when useful, and prioritize clean infra, monitoring, and team enablement so models actually run without falling over.
