Geesly — Dating app

A cross-platform dating app in the spirit of Tinder, Hinge, and Glam. Real-time matching over Firestore, geospatial discovery, in-app currency ("corns"), RevenueCat subscriptions, rewarded ads, and Vision-API content moderation. Localized in 9 languages. The hardest lesson has been distribution — shipping the app is only the first problem.

Auto-generated Open Graph images, ⌘K global search, and cookie-gated admin curator tools (entry-type editor, canonical-order editor, HLTB batch refresh).

MaxCandela — Brighter MacBook XDR displays

A focused macOS utility for MacBook Pro XDR displays that unlocks the panel's extra brightness from the menu bar. The product page explains the problem clearly: macOS caps everyday content below the display's rated peak brightness, while MaxCandela gives users a one-click way to reach full brightness with true colors, no setup, and no account required.
