Editorial interest 78/100 Selection signal · not a rating of the site

An independent developer’s portfolio of narrow software products, including tools for passport photos, sheet music, cross-stitch patterns, trading charts, and TikTok slideshows.

Landing page captured for the 2026-09-20 issue.

For: Independent software builders and product observers
Worth noticing: The portfolio covers five live products and one reported 2026 exit.

Field notes

The page documents a portfolio built around small, concrete inputs rather than a single broad platform: a chart screenshot, a passport photo, piano audio, a personal image, or a product URL. Its product descriptions name practical outputs such as country-specific photo checks, PDF/MIDI/MusicXML files, DMC thread numbers, and generated TikTok slideshows. Zeriflow is presented separately as a completed sale rather than as part of the current work.
