Projects and Tools

Everything I’m running right now. Some of it makes money. Most of it just teaches me something. The ones that died don’t get deleted — they get autopsied.

🪦 Dead, but documented

My Postmortems series — honest autopsies with real numbers, because a $0 launch teaches more than a fake success story:

• MailIELTS (#001) ~ AI IELTS writing coach. 714 commits, 467 posts, 21 months, $0.
• NanoPhotoStudio (#002) ~ AI portrait studio that never launched. 1,648 commits, 282 PRs, 27 weekly visitors, $0.
