A CLI written in Go that can edit Firebase Auth Claims. It can handle different permissions that a normal application can only read and only for the currently logged-in user.

The idea is to be able to list and modify privileged users easily. But listing users with only a special claim, or even any claim, is not a feature of the Firebase API. That's why listing all privileged users works only by looping through all Auth users and filtering to the ones having at least one of the interesting claims. This is slow. That's why the result list of privileged users will be saved in a Firestore document, and updated on later changes.

FEATURES
1. Refreshing cached list of privileged users. This can be useful for:
• Building a cache for the first time.
• Building a cache after the list of interesting claims has changed.
• Considering a refresh because of suspicious manual changes to the Firestore cache or the Auth claims.
2. Printing a cached list of privileged users.
3. Printing a search result based on email or name. This also uses Firestore because searching in Auth is not possible.
4. Changing permissions on the listed users and saving them to Auth claims and the cached Firestore list of privileged users.
5. Undoing yet unsaved changes.

A small cross-platform mobile and web app that prints daily data based on the Chinese five elements zodiac system. The user can swipe or choose another day in the calendar.

The app is available in the Google Play Store https://play.google.com/store/apps/details?id=io.github.vendelin8.elements

This library is a part of a bigger project. The GUI for that project was written in ExtJS, and it conflicted with the charting modules available at that time. As a solution to this, we decided to write our own library, which was my task. The CEO and other team members let me open-source it.

It is an HTML5 Canvas-based chart module.

FEATURES
• It can show candlestick charts, line plots, bar charts, and distribution diagrams.
• The x-axis can contain date/time values or data indexes.
• The y-axis limits fit automatically to the displayed data.
• Under the chart, a zoom panel is shown if necessary. The user can zoom in and zoom out with a mouse scroll and pan the shown window left or right.
• Mouse hover shows a tooltip about the current value at the mouse position.
• If showing multiple plots at the same time, a legend is shown with the names and line colors.
• Indicators can be created that are calculated based on the loaded data.
• Data can be loaded at any time, appending after or inserting before the current data.
• Different color schemes are supported.

A small CLI that prints daily data based on the Chinese five elements zodiac system. The user can move the calendar by one day, month, or year to check different dates, and the console updates without adding new lines.

A Flutter-based web and mobile app to display information from the Chinese five elements zodiac system. It uses a Firebase back-end. There's a personal page where users can look at their own personal formulas. There's a consultant page where experienced users can look at their clients' formulas and calculate more complex information.
