What I'm looking for

I seek roles building production ML/LLM systems with strong engineering practices, model transparency, monitoring, and cross-functional impact.

I am a machine learning engineer focused on building safe, reliable, and compliant AI systems that drive measurable operational improvements. I have engineered production-grade RAG systems integrating Google Gemini with Weaviate and implemented end-to-end ML pipelines with strong engineering practices.

My work spans scalable data processing, containerized microservices in Go, and model optimization for resource-constrained hardware, delivering up to 90% efficiency gains and 30% throughput improvements. I emphasize model transparency, monitoring, and high test coverage to ensure accountability and maintainability.

I collaborate cross-functionally to deliver tooling and dashboards for model performance and auditability, and I have a track record of publishing research and winning innovation awards for applied ML solutions.
