What I'm looking for

I seek a hands-on role building and scaling LLM training pipelines with strong MLOps practices, collaborative teams, and opportunities to improve model performance and deployment.

I am an experienced AI model trainer focused on large language models, fine-tuning (LoRA, PEFT), RLHF/DPO, and automated training pipelines. I design and implement training programs using Hugging Face, LangChain, and third-party APIs to improve model accuracy and performance.

I have led dataset curation, annotation, and evaluation efforts, documented system specifications and training processes, and collaborated cross-functionally with engineers and data scientists to resolve model limitations and scale deployment. My work emphasizes reproducible pipelines, reward modeling, and measurable performance metrics.

I hold an engineering bachelor's degree and an MBA, and I maintain professional certifications in AI technologies. I seek roles where I can drive MLOps best practices, build robust RLHF workflows, and deliver production-ready LLM solutions.
