What I'm looking for

I'm seeking senior ML/AI roles where I can lead technical teams, build production-grade NLP and LLM systems, design MLOps, and drive measurable business impact.

I'm a hands-on Machine Learning Engineer and data scientist with 8+ years building end-to-end AI solutions and leading technical teams. I specialize in NLP and LLM applications—fine-tuning language models, building RAG systems, developing AI Agents, and deploying models that handle real-world text at scale.

I've delivered production ML across fintech, insurtech, real estate, and retail, working with C-level executives to translate business challenges into technical strategies. I design MLOps infrastructure, build and mentor high-performing teams, and ship models in production using tools like Hugging Face, PyTorch, AWS, GCP, and Docker.

My track record includes establishing ML/DS functions from scratch, improving conversion and retention metrics, reducing model development time, and deploying robust NLP and prediction systems that cut costs and improve user outcomes.
