Businesses lose thousands of hours a year to manual data entry and repetitive workflows. I build the AI systems that eliminate that permanently.
What I deliver:
— Invoice & document extraction (YOLOv8 + OCR, structured JSON output, 95%+ accuracy)
— Business process automation (Python, n8n, Make, API integrations)
— Computer vision systems (defect detection, object counting, real-time camera analysis)
Every project I deliver is production-ready, documented, and built to scale. I don't disappear after handoff.
Currently available for fixed-price projects and retainers. Message me with your bottleneck — most projects scope out in one conversation.
