About Me — An Old Programmer Who Refuses to Be Defined

Hi, I am Luo Xingchen.

For the past 12 years, I have been an "Android Development Engineer". From Java to Kotlin, from Eclipse to Android Studio, from MVC to Compose, I have experienced the golden age of mobile internet. I was a core architecture member of apps with millions of daily active users, led teams, handled 3 AM emergency failures, and in the nights when I pushed crash rates from 5% to 0.1%, I found the true fulfillment in this profession — not in how much code I wrote, but in how many people I helped solve real problems.

In 2026, I decided to "graduate" from the factory assembly line.

Not because of burnout, but because I wanted a different way of living. I want to use the experience accumulated over these 12 years to connect with more people who truly need me — startup teams, traditional enterprises undergoing transformation, or independent creators with brilliant ideas but lacking technical implementation. At the same time, I am systematically expanding my skill set in HarmonyOS NEXT, frontend, and backend — not for anything else, but so that when needed, I can single-handedly build an entire product line.

What can I do for you?

• Architecture Design & Refactoring — Make your project stand the test of time and high traffic.
• HarmonyOS Migration — Smoothly migrate Android code to HarmonyOS NEXT, avoid the pitfalls I have encountered.
• Performance Optimization — Slow startup, jank, OOM? As long as you can reproduce it, I can find the root cause.
• MVP Rapid Validation — Full-stack development from frontend to backend, turn your idea into a demo-worthy product within a week.

My Work Philosophy:

No unfinished projects, no mindless coding, no betraying trust.

If you have a technical challenge that needs someone who can "get it done", feel free to send me an email. We can start with a cup of coffee (online or offline).
