I worked here for a year in 2021. Our team at Discount Office Items (www.officesupply.com) wrote a site that deployed to AWS, offered 80,000 items, and handled thousands of sales transactions per week, grossing millions of dollars of sales per month. The codebase had been forked from OpenStore opensource around 2012.

I made small modifications to the php + Symfony, wrote some unit tests. I never mastered the complexity of writing for such a large site. I was unprepared for the coding -- the day I started I didn't know any PHP and that's what the whole site was written in. But I learned a lot from their Agile sprints and retrospectives. I got good with the organizational tools: backlog tool, chat, working in teams, running retrospectives. Overcame the fear of jumping in to a giant codebase, doing research, asking for help and not being intimidated. Didn't accomplish much to the code but learned to work very independently for a day or two at a time and try lots of things.
