What I'm looking for

I'm open to remote work with international teams.

At Y99 Pawn Joint Stock Company, I built the core loan platform, covering applications, approvals, disbursements, repayments and collections. I designed 16 modules with 60+ PostgreSQL tables, 200+ APIs and 140+ screens, and implemented calculations that give credit and accounting teams the same figures.

I also built Y99HR, a shift-planning and attendance system, and the company’s public loan website and CMS. I connected website inquiries to the loan system with fallback storage, and integrated VietQR and bank webhooks for payment confirmation.

As a freelance developer, I’ve delivered booking, dealership, venue discovery and e-commerce products for businesses in Vietnam and Singapore. I’m also building PETID Vietnam, a digital pet ID product with connected apps, dashboards and QR tags that let anyone who finds a lost pet reach its owner.
