Hello, I'm Tim

Introduction

I love designing and building things that help people. I am a Frontend Developer with over five years of experience, creating web and mobile apps with Next.js, TailwindCSS, and TypeScript. I enjoy exploring new technologies and turning ideas into polished personal projects.

I live in Walnut Creek, California with my wife and daughter. I’m originally from Mongolia and studied Computer Science in Germany at the University of Mittweida. I speak English, German, and Mongolian, and even a bit of Russian.

How I got started

After leaving my corporate job in 2011, I jumped into mobile development and launched two apps. One was a Local Marketplace App, and the other was a Custom T shirt Design App featuring Mongolian designers. Those early projects became the foundation for everything I have built since.

Android Development

In 2018, I began learning Kotlin, Jetpack components, and modern Android tools. I published two more apps, and one of them was featured on a well known Android YouTuber’s channel here. That recognition gave me a big boost.

Web Development

Great mobile apps need strong backends and clean landing pages, so I explored Next.js, React, and TailwindCSS. I quickly fell in love with Next.js and TailwindCSS for their simplicity. I built two full stack Next.js apps that earned more than 450 GitHub stars and received official recognition for my open source contribution in the form of Vercel Swag from former CTO Lee Robinson. My portfolio was also featured on WeAreDevelopers.com.

Today

I discovered that I am much more suited to frontend development than Android development. My focus has shifted to Next.js and Tailwind CSS because I am far more productive with them. The workflow feels fun and flexible. I can build and ship fast, test ideas quickly, and reach users instantly without separate Android or iOS builds. I can prototype in hours instead of weeks and see real usage right away. I am currently learning and improving my skills by building personal projects.
