FULL STACK DEVELOPER
A developer who enjoys building modern web applications and turning ideas into real products. I like working across the whole stack, from creating clean user interfaces to building APIs and deploying systems to the cloud. I’m always interested in learning how technologies work under the hood and improving how applications perform and scale.
ABOUT ME
Hi, I'm Htet Wai Yan, a full-stack developer with over 5 years of experience building web applications. I've worked with technologies like Angular, React, Next.js, Vue, and Svelte on the frontend, and Node.js on the backend. I also have experience working with AWS and deploying production-level applications.
In my previous roles, I worked on systems used by thousands of daily users and built features like payment integrations, cloud infrastructure, and CI/CD pipelines. I enjoy solving real problems and building products that people actually use.
Currently I'm working as a freelance developer, but I'm interested in joining a larger company where I can collaborate with a strong engineering team, learn from experienced developers, and work on bigger products.
