How Flavio Moreno Builds

Moreno's GitHub introduction says he began programming with Java at thirteen, uses Ubuntu, and likes JetBrains software.[1]

I enjoy learning new things to become a better developer, always improving my code and my workflow.

crNormz provides a concrete implementation example: a command-line checker with configurable exclusions, severity filtering, and raw output for integration with other applications. Its documentation also lists unsupported cases and unfinished checks, making its limitations inspectable.[3]

Alldle extends a directory into an integration platform: its optional SDK reports completed rounds and synchronizes a player's daily checklist, while creator dashboards expose audience and retention information.[4] The reviewed profile and repository do not establish use of a particular AI coding assistant, so this draft assigns no AI-tool relationships.[1][3]

Business Model

Alldle states that listings are free and that inclusion and rankings cannot be purchased.[2] Its creator page also says the dashboard and SDK are free, with no commission; creator payments are described as planned, not already operating.[4]

These statements establish the current offer to creators, but do not establish Moreno's income or the portfolio's profitability.[2][4] No qualifying revenue disclosure was found in the reviewed sources, so the revenue table remains empty.

Timeline

  • A dated crNormz commit updates the project's README.[11]
  • Alldle's privacy policy carries this update date and documents audience measurement, reminders, and creator emails.[12]
  • At review, Alldle identifies Moreno as its sole operator and offers free creator listings, dashboards, and SDK integration.[2][4]

Lessons

Alldle also distinguishes outbound clicks from results reported by integrated games. That distinction illustrates why a directory should explain what its engagement metrics actually measure.[2]
