Who I am

Software Engineer
Fintech Specialist
EU Job Seeker
Team Mentor

"A developer who cares about real impact — not just clean code."

I'm Aoy, a software engineer from Vientiane, Laos. I've spent 3+ years building financial products that real people use every day — from E-wallets to AI-powered bank account opening flows.

I work across the full stack: Flutter for mobile, React.js for web, Node.js & Python & Java Spring Boot on the backend. I've shipped to four app stores, integrated payment networks (LaoQR, Visa/Mastercard), and built AI chatbots(Hauwei API) people actually use.

I'm looking to experience in Europe — especially the Greater Region around Luxembourg and nearby EU hubs where fintech, banking, and cross-border tech are strong.
