I worked really hard on two side projects during the pandemic that I am quite proud of (here you can take a peek if you like): www.hopupon.com, www.audiobookmate.com
When I was younger I used to list side projects on my cv and employers used to take notice. I find now they don't seem to care, usually are only interested in employment history and tech tests.
I also wonder whether side projects speak to the fact that you're not concerned enough with your employer's bottom line. I remember when Ken Cosgrove, in Mad Men, had a side gig as an author and got published in a magazine. Roger Sterling told him, quite sternly, he had to choose between the job and the gig.
The thing is I would actually appreciate if a potential employer asked me about the above two projects. I think they demonstrate some of my skills and would be interesting to discuss.
What do you guys think: Do you guys still list your side projects? What about for jobs more senior than senior developer?
Hyperbole time but I think it conveys the message: People do side projects for better reaons than they do professionally. At worst it's because they want to quickly learn/achieve something for their next job. Compared to professional experience, where at best it's because they were paid to do it and any fun or whatever altruism is a byproduct.
There are lashings upon lashings of caveats and nuance of course. For a senior role I will still be looking for interpersonal skills not just technical achievement. Part of being a senior is managing yourself, selling your ideas/concerns, mentoring and managing peers, and to some extent managing your managers.
FWIW your side projects are great examples and I'd would be impressed.
