Applied Data Analytics @ Boston University | LlamaIndex · PyTorch · NLP · Vector DBs | Open to remote AI/ML roles **Profession:** Technical Support **Location:** United States ## About Kehinde Akinwumi is an AI/ML engineer focused on Python-based LLM, retrieval-augmented generation \(RAG\), and document-intelligence systems, while currently working in Technical Support at Kfrosh Web-Net and completing an M.S. in Applied Data Analytics with an AI/ML concentration at Boston University. Kehinde is strongest in turning unstructured images and documents into searchable, evaluable data products through OCR, vector retrieval, fine-tuned language models, and rigorous model testing. At Outamation, Kehinde built an end-to-end mortgage-document intelligence pipeline that automated classification and extraction across more than 500 PDFs, achieved 94% classification accuracy, and reduced manual review by 60%. The work included LlamaIndex retrieval across 130+ documents, reducing search from hours to seconds, and an OCR annotation workflow that increased classification accuracy from 78% to 94%. Kehinde also brings an IT and network-support foundation, SQL and ETL experience, and a deliberate transition from statistics and Python foundations into machine learning, deep learning, NLP, and production retrieval systems. Kehinde is open to remote AI/ML engineering roles in retrieval, LLM applications, and document intelligence. ## Services - Matplotlib - Pandas \(Software\) - Scikit-Learn - Microsoft Power BI - Predictive Modeling -
