Notifier

Build MVP

There was a lack of services that let users easily convert different data sources to RSS feeds.

First I wanted to validate my idea. So I build a simple web service, where a user could get a unique email address or HTTP webhook and receive all messages sent to it via RSS. It was free, and no sign-up was required.

A few users started using it, so in the next iteration I added integration with Telegram. Notifier was the first project that let users read Telegram channels via RSS, so it got good traction.

A few months later I also added paid plan and started charging users.

Improve workflow

To make sure all main functions are valid I created unit and automated tests. After each commit, the code is deployed to Semaphore CI, where the tests are run.

I set up errors logging and different types of reporting depending on an error level. For example, in case of a critical error, I immediately get an email notification with the error details. For non-critical errors, I get a daily summary.
