Full-stack 3D web developer behind DirectCrest, a B2B sourcing platform with interactive 3D product inspection and automated fulfillment.

DirectCrest is a B2B sourcing platform I architected to connect global buyers with factories. It brings together interactive 3D product inspection, RFQ workflows, and automated supply-chain tracking.

On 3D Universe, I engineered a zero-code platform for creating interactive 3D WebGL environments from business metrics. I paired its creation engine with a three-part architecture and OpenAI API copywriting tools.

At Digital MEL Hub, where I work remotely as a Digital Marketing Officer & Video Editor, I promote webinars, courses, eBooks, and consultancy services. I also produce video content and work on SEO, GA4 tracking, and Mailchimp automation; alongside this, I’ve conducted household and mobile field surveys using KoboToolbox.
