What I'm looking for

I seek senior AI/ML roles where I can lead end-to-end model development, scale MLOps, mentor teams, and deliver measurable business impact in a collaborative, product-focused environment.

I am a Senior AI/ML engineer with 8+ years building end-to-end intelligent systems across healthcare, retail, trading, military, and industrial domains, focused on deploying production-grade models with TensorFlow, PyTorch, and Scikit-learn and operationalizing LLMs, RAG, and computer vision solutions.

I design scalable data pipelines and MLOps on GCP, AWS, and Azure, mentor teams, and integrate AI into secure, high-performance microservices to drive measurable business impact such as improved inventory turnover, cost savings, and enhanced automation.
