Ask HN: Would you ever work on your SaaS at your day job?

Do you think it's a reasonable risk to work on my SaaS at work? My context:

I have 1-2 hours of free time each day max, if nothing comes up. This is because I have a baby. The 1-2 hours sacrifices perfect sleep.

My job on the other hand is not always demanding. I might be able to get a good 2 hour block in for myself. In addition, I have private space and my company is not in software, so they are more likely to be unaware.

My SaaS idea is intended to be a personal scale business, so even if caught it's unlikely my company would be interested in it. Totally unrelated to their business as well. There is a slim chance my idea can catch on larger than I expect, but I'm not banking on it.

I also do not come from a CS background, so it takes me triple+ the time of what some of you can hack out a site. I've only created one app and I have to learn new tools for this new one. Thus the time crunch is even more extreme.

I can work on my app through a web IDE and private IP (HTTPS). Will the company be able to detect it? Alternatively I can shell out for a new Macbook I suppose, since I have private space to work.

My idea if successful will need some network effects to keep away copycats, so I'd like to be able to work full bore. However I cannot afford to quit my job.

I'm in California. My employer is not based there. I did not have to sign any IP agreements.

Would you work on your SaaS on the job if you were me?

Thanks.
