About

I write code, build things, and write a few other things.

ArvelVale

I'm ArvelVale, a senior computer science student working on AI applications and full-stack development. From idea to launch, I like to walk the whole chain myself: design, code, deploy, and then look back at what went wrong.

My road has not been smooth. In my last year of middle school, stuck at home during the pandemic, I taught myself from online courses on Bilibili and climbed from the middle of the class into the top ten. In high school I worked my way up to first in the class, and before the college entrance exam I went home and studied alone for a stretch behind closed doors — and it still did not come out the way I wanted. In my first year of university I switched from mechanical engineering to computer science on the strength of my grades, and my CET-6 score went from 349 on the first try to 475. After a few ups and downs I kept one habit: when I want to learn something, I build something with it first.

I am fascinated by how to let AI genuinely act for people without people losing control. That is why I built a session manager, a dev-flow agent and a companion app, and why I write about it here.

I lean introverted, and I tend to think a thing all the way through alone before I act. What I have been practicing for the last two years is the opposite: showing my work to other people earlier. Hackathons, open source, and posting on Bilibili and X are all part of that practice. I believe the seed is mine, but it has to grow in soil. I wrote about that in Self as Seed.

What I work on

AI apps and agents

A dev-flow agent, a session cockpit, a companion app. I care about whether decisions can be seen and writes can be stopped.

Full stack and deployment

Front end, back end and operations, all by myself: React, TypeScript, Python, FastAPI, Tauri, plus Linux and static-site deployment.

Writing and visuals

Articles and visualizations to make what I learn clear: software design, architecture, how AI works, and now and then reading notes and the I Ching.

Videos made with code

Animations, explainers and short dramas drawn in code, with AI for voice and music. One of my videos on Bilibili passed 10,000 views; the series I am building is still very early.

Background

  1. Switching majors

    I moved from mechanical engineering to computer science in the first term of my first year, and caught up from scratch.

  2. Community and contests

    At the Datawhale summer camp I was named one of the 20 most popular AI super-individuals; I won third prize at the WaytoAGI global hackathon; and I joined Yukesong and Nankesong S2. No prizes there, but I shipped something demoable every time.

  3. AdventureX · July 2026, Hangzhou

    As soon as the Cross-Strait contest ended, I flew straight from Chengdu to Hangzhou. I did not win a prize, but I met many people who build things, and it felt far better than campus contests. We built an AI companion that helps people sort out their thoughts. After the event I kept working on it, and it became Miaoling: an Android app and a website are out, and a HarmonyOS version is in progress.

  4. NVIDIA DGX Spark Hackathon · September 2026

    With a team I built KROVIN, a dev-flow agent running on DGX Spark: it reads Linear issues and Obsidian notes, then breaks down, plans, codes and syncs. I mainly handled the agent architecture, the skills design and the overall integration. Its decision layer logs which skill was chosen, which model was used and whether a tool was allowed as a measurable trace, so every step can be reviewed afterwards. We submitted on September 29.

  5. Building

    Team projects Qiguang and an LLM-powered lab-teaching assistant have won awards; since May 2026 I have been interning at a company that builds an AI teaching platform, working on the full stack. Personal projects are on the projects page.

  6. Campus

    Class psychology officer, youth league staff, head of publicity for a university cybersecurity club, and an outstanding volunteer in a remote-teaching program.

Outside work

Books
Steve Jobs, Elon Musk, The Almanack of Naval Ravikant, Zen in the Art of Archery, Hidden Potential, Designing Your Life. I only started reading in my second year and want it to become a long-term habit.
Travel
I like traveling, and I like building things on the road. On the National Day holiday in 2026 I went to Xi'an, and when I came back I used code to turn my photos into a handscroll video that unrolls.
Dreams
I've written down dozens of dreams, thousands of words. I don't try to explain them; they are just fun.
Other
Anime, the British series Doctor Who, psychology, astronomy, and a little I Ching (two posts on it here).
