I owe the current (probably final) phase of my professional IT career to Django, now having used it in production of ~15 years. I got in around the 1.0.* release mark so I missed any possible early instability, and have found it an absolute pleasure to build with since. It's been stable, reliable, regularly updated and (importantly) easy to teach to new devs. The documentation and API have only gotten better in the intervening years. It remains (along with PostgreSQL) one of the few technology choices that have we have never regretted or second-guessed in my organisation.
