I specialize in WordPress Shopify ACF & PHP SaaS Full Stack
I'm Kaung Htet Win — most people call me Zhang. For six years I've built what banks, agencies and international brands actually run on: 80+ projects for 55+ clients, from enterprise WordPress to Shopify storefronts to custom business software. I ship my own SaaS products too — so I build your project the way I build mine, for whoever has to live with it after launch.
Websites, storefronts and custom software — designed, built and shipped by one engineer. No account managers, no handoffs, no waiting in someone else's queue.
End-to-end web apps and SaaS products — frontend, APIs, database, auth, billing, deployment. One engineer owns the whole build, so nothing falls through the gap between handoffs.
Stores built to convert, not just to look good. I built Buy Buddy — an AI sales chatbot now running on live stores — so I know what actually moves a shopper to checkout.
Enterprise WordPress with Advanced Custom Fields — so your team updates content without touching code, and the site survives its next redesign instead of being rebuilt from scratch.
Technical SEO built in from day one — Core Web Vitals, schema markup, and load times that move rankings and revenue, not just your Lighthouse score.
Configurators, dashboards and integrations built around how your business actually runs — not how an off-the-shelf template assumes it does.
A full diagnostic on your existing site — design, performance, SEO and security — plus a prioritised list of what's broken and what to fix first. The same pass I run before touching any project.
Banks, hospitals and international e-commerce brands. Every one of these is in production today — click through and check.
Enterprise WordPress for a leading Myanmar bank. A custom ACF architecture lets their team publish changes in minutes instead of raising tickets — with compliance-grade security underneath.
