Built and maintained the PO Processing System a full-stack platform that automated extraction of purchase order data from multi-customer PDFs using OCR and regex, feeding a FastAPI backend with React/MUI frontend and Azure SQL storage. Developed a computer-vision pipeline for fraudulent cheque detection: manipulated cheque images to be undetectable to the human eye, curated a labelled dataset, and trained a classification model achieving high detection accuracy (Roboflow, OpenCV, Flask, Google Cloud Vision, GPT-4). Built an NLP-based theology book translation pipeline that translated entire books into Greek, Arabic, and Roman script using dictionary lookups and Google Translate API, with MongoDB as the storage backend. Designed a PDF and table extraction engine using pure regex (no AI) achieving 95%+ extraction accuracy across diverse PO formats from 7 different retail customers and later integrated into the client's platform Developed a cattle detection system using computer vision object detection for livestock identification and counting
