Data Scientist & Machine Learning Engineer at Prospect33, cutting manual data entry by 80% with OCR pipelines.

Kenya

Message

At Prospect33, I built and deployed OCR pipelines using Tesseract and AWS Lambda that extracted structured data from image-heavy PDFs, reducing manual data-entry effort by 80%.

I also deployed and monitored production ML models on AWS, and integrated LangChain and RAG document processing into a data platform for AI-driven analytics in a regulated financial environment.

Previously, I contributed to backend and ML systems at Fleet (Logistics) and Neural Labs Africa, including Postgres data pipelines for route optimisation and FastAPI inference services for clinical image analysis. I hold a Data Engineer Certification from DataCamp.
