Wai Yan Aung @ William

Lead Web Developer · Founder of Digital Tree

I work across the full software lifecycle — PHP (OOP / Laravel), .NET Core (C#), Python (Django / FastAPI), Node.js, React and microservices. I design REST APIs, build multi-tenant HRMS platforms, run Linux servers and lead cross-functional teams, with multi-cloud experience on AWS, DigitalOcean, Azure and Google Cloud. AI tools like Claude Code, GitHub Copilot and Cursor are part of my daily workflow.
