Hello, I'm Tim

Introduction

I am a Frontend Developer with more than 5 years of experience building modern web applications with Next.js, TailwindCSS, and TypeScript.

I currently live in the San Francisco Bay Area with my family. I am originally from Mongolia and studied Computer Science in Germany. I speak English, German, and Mongolian, and I also understand some Russian.

How I got started

In 2011, I bought an Android development book and started learning Android using my existing knowledge of Java and Eclipse. During my student years, I built small projects with Eclipse, Java, and XML. While learning Android development, I built and launched two Android apps on the Google Play Store. 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

After launching my first two apps in 2011, I took a long break. In 2018, I returned to Android development and started 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 460 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

My focus has shifted to Next.js and Tailwind CSS, where I am significantly more productive. The workflow is fun and flexible, enabling me to ship fast, test ideas quickly, and reach users instantly. I am continuously improving my skills through personal projects.
