Hi, I’m Hank (Phạm Dũng)
I build fast, delightful web & Shopify experiences.
Full-stack engineer specialised in high-performance Shopify apps, design-system-driven React UIs and the unglamorous backend glue that keeps merchants shipping.

Things I’ve shipped
A few projects I’m proud of — Shopify apps I built on my own and with the team at Mageplaza.
Engineering that ships and scales
I work across the stack, but I care most about the seams — performance, DX and the details users feel but never name.
Shopify App Development
Embedded admin apps, storefront widgets and theme app extensions that pass review and scale.
Web Performance
Core Web Vitals work: render paths, bundle budgets, caching and zero-CLS layouts.
UI/UX Engineering
Design-system-driven interfaces with motion that earns its place.
APIs & Integrations
GraphQL/REST services, webhooks and third-party integrations that don’t fall over.
Have something worth building?
I’m always up for a good problem — a Shopify app, a gnarly performance bug, or a green-field product. Let’s make it fast and delightful.
