I know how you feel. I had two years of crazy profitability then two more trying to revisit the highs, before getting bored and selling the business at fire sale price.
The reality is that you have raised your bar and now what seemed like success won't be enough.
BUT your business wasn't successful ONLY because of the pandemic. You got a bit of luck which augmented something you were already doing something right. The world was moving to online anyway, the pandemic just sped up that process.
For me, my 'luck' came long before the pandemic when the government introduced a new requirement for schools and my company was in a great position to exploit it. Had two years in the sun (literally) before bigger companies were able to catch up and kill my profits.
There's always an element of luck - good and bad. But now you need to figure out how you can achieve greater levels of success (if that's what you want) relying less on good fortune and more on whatever it is that you do well.
I have the opposite problem. And may be able to help you.
I was a senior developer at a UK startup. The MVP I built helped them raise £9M in series A. I've also launched multiple products myself, including a Shopify app.
Right now I am trying to launch an AI startup. I want to do it without raising VC so would like to have some gigs on the side. I tried UpWork but don't have time to build up a profile, nor compete against the rest of the world.
When I look for developer jobs here, they are always long contracts or permanent. I don't want that; I need flexibility.
I had thought about specialising in Shopify. I think it's well thought-out as a platform, and though I prefer to get involved in more complex stuff, I wouldn't mind doing small tasks like building pages, creating integrations etc
