Daniel Juan

Software Developer & Systems Engineer

Passionate about computers since childhood, I wrote my first lines of code at 13 years old. Over the years I've worked across infrastructure, backend development, automation, and AI-powered workflows. From managing enterprise environments with CCTV fleets and Active Directory to building e-commerce integrations and OCR pipelines. Deeply interested in reverse engineering and understanding how systems work from the inside out.
