However, I've built amazing things for amazing companies when I do get jobs. I've architected and built end-to-end products by myself and within teams. A few projects I've worked on: a web scraping product, data labeling software for machine learning, commercial eyetracking software, a custom learning management system, machine learning models from scratch, high volume image processing, etc. In each of these projects too I did end-to-end work. Development, deployment, infrastructure, ops.
Each one of these products though was with a different stack. JS, C#, Clojure, C++, Java, Python, the list goes on.
Common feedback I've received is that I'm not experienced enough to deliver in a role. Anecdotally, engineers that I talk to where I'm located have spent their entire careers using only JS, building Next.js sites or whatever the current hotness is. Not that there's anything wrong with that, but it does seem like the landscape has shifted to the specialists.
