dev-dock-manager-rust
One Docker dev box per user, with a web terminal, a noVNC desktop and optional GPU. The Django version, rewritten in Rust, partly to find out whether I could.

Nat Lee
An engineer who got promoted into meetings and keeps sneaking back into the codebase.
These days I forecast Japan's electricity prices, and build tools so I never have to open a VPN again.
$ cat now.txt
building power-trading systems for Japan's electricity market: market and weather data pipelines, bidding tools, spot-price forecasts.
Flagship project
Telepy
Reach every device from your browser.
One outbound reverse SSH tunnel per device gives you a browser terminal, files, remote desktop, a remote browser and the LAN behind it. No port forwarding, no VPN, no public IP.

A few projects that show the range: trading data, developer infrastructure, computer vision and small tools people actually install.

Where I've been
Four rooms so far. Each one taught me something the next one needed, usually the hard way.
2018 – 2019
Crawlers & NLP
First job. Scraped the web, trained language models, learned that regex is a lifestyle.
2019 – 2021
Computer vision
Medical imaging, retail analytics and ads on embedded boards. Stared at a lot of pixels.
2021 – 2023
NLP & data platforms
A sentiment platform over three billion data points. Most of them were complaints.
2023 – now
Energy trading
Solar forecasts first, then power trading for Japan. The weather is now my problem.
How I work
Most of what I build now, I build together with AI coding agents. I decide what to make, how the pieces fit and whether it actually works. The agent writes a lot of the code, and I read every change before it ships.
