What I'm looking for

I want to build production AI (LLM/RAG, NLP, predictive maintenance) and work cross-functionally to ship measurable business outcomes, improving model robustness and deployment reliability.

I’m an AI/ML Developer with 4+ years of hands-on experience building production-grade machine learning systems, Generative AI pipelines, and NLP solutions. At IBM, I led AI integration for industrial predictive maintenance using Maximo Predict and built end-to-end GenAI pipelines (LLMs + LangChain) including RAG-based knowledge retrieval over enterprise documentation.
