Hi, I’m Zhiwei.
I’m a software engineer with 12 years of experience spanning iOS, Android, frontend, backend, and AI. I’ve worked across live-streaming startups, cloud computing platforms, China internet products, and financial systems at Singapore and Hong Kong banks. I’m actively moving into AI engineering — training GPT-2 with nanoGPT on H200 GPUs, consuming ~3 billion tokens via LLM APIs (~500M last month alone), building personal agents and automation tools. I ranked top 6% in AI assistant usage globally at my current employer. I want a role where AI, agents, and LLM work are the main job — not a side project.
📌 Highlights
- 12 years of engineering experience across iOS, Android, frontend, backend, and AI
- Worked across diverse domains: live-streaming startup, cloud computing startup, China internet products, and financial systems / digital banking apps of Singapore & Hong Kong
- Born 1995, Chinese citizen, based in Guangzhou; IELTS 6.5 (Reading 8.5)
- Enrolled at Beijing Forestry University (2013–2014), dropped out; pursuing Associate Degree via self-study — 13 of 17 courses passed
- 2011 NOIP Guangdong province, top 300 provincially; 1st prize (Guangzhou round), advanced to provincial round
- Founded Fun Live (live-streaming app, 30,000 users) and Square Root Technology; reached 3M CNY revenue with 600K CNY profit in 2018
- Received a job offer of ~384,000 CNY/year (~32K/month) around 2023, without a bachelor’s degree
- 10+ open-source GitHub projects (500+ commits each); ~400 technical blog posts; ~8,000 AI answer notes
- Trained GPT-2 124M with nanoGPT twice (RunPod H200, DigitalOcean H100, home RTX 4070); ~3 billion tokens consumed via OpenRouter & other LLM providers in the past year
- Built ww (CLI toolkit), iclaw (AI coding REPL for enterprise environments), and zz (dataset processing & training utilities for ML projects)
- Self-taught researcher — 3 papers on natural vision restoration; reversed myopia 350 → 250 diopters over 3 years

| ## 🔍 Why I’m Looking |
My current job at the bank has been going well — I’ve been performing strongly (top 20% among contractors at my vendor, top 6% in AI assistant usage globally at my employer). But due to some project change and some other reasons, I will leave at the end of July 2026 to pursue the next chapter on my own terms.
My primary motivation is becoming fully AI-centric. I have technical idols — Yin Wang, Andrej Karpathy, Wenfeng Liang, Greg Brockman — and I want to grow in the direction they represent: deeply technical, AI-first, and building things that genuinely help companies and users. My current role only involves AI tooling at the edges, and I want AI, agents, and LLM systems to be the core of my work.
My plan is two-pronged:
-
Start a one-person company — I’ve built multiple products end-to-end before (Fun Live, Square Root Technology, 3M CNY revenue), and I want to ship AI-native products and services independently. I have the infrastructure (RunPod H200, RTX 4070, 3B tokens/year of API usage), the tools (ww, iclaw, nanoGPT), and the domain knowledge to build real AI solutions for clients and users.
-
Explore AI startup opportunities — I’m interviewing with AI startups and AI-focused roles to see what’s out there. If there’s a compelling mission with the right team, I’d join over going solo. I’m open to early founding member, founding engineer, or IC roles where AI systems are the product, not a side activity.
That said, given my reality, contractor or permanent positions at big banks that combine AI with backend or full-stack engineering are welcome too — I know that space well and can contribute immediately. But my strong preference is for positions where AI, agents, or LLM work are central.
Compensation improvement is a secondary but real motivation. Leaving means giving up a stable income stream, and I want whatever comes next — whether a company or a role — to better reflect my experience and output.
