At a previous job, I worked on a multi-vendor e-commerce website. It used Magento2 as an API and a separate application we built with Node, Express, and React that consumed it to avoid using Magento's frontend.

The whole stack used should be a rant in itself but our checkout process was dependant on work done by some contractors in India. In short, this entire checkout process would break multiple times a day with no way on my end to fix anything, and that's what I had to reply with every time a bug ticket would come in; which is honestly the worst reply ever to a huge issue like that.

After several attempts of pitching the idea and being turned down for building the checkout in-house to remove the dependency and work on even streamlining the process, the product manager of the brand said as quote "Well the checkout isn't really that important".

At first, I was kind of speechless. How is the functionality of actually buying a thing in an online store NOT important? Shouldn't that be the most important?

Then I realized over time that the only thing they cared about was being a Nascar version of a website, essentially being a canvas of ad space that sellers on the marketplace could buy and paying money just to list their items.

I hated working on that project, and that made it so much more soul-crushing. Gotta chase that revenue right?
