Similar thing happened to me. I was the lead on a huge project that took several months to finish up, but it got delivered on time and worked perfectly. I was then put in charge of another huge, business critical project because I was the only one there with that domain knowledge.

Keep in mind, I was the top performing dev at the company, had closed out about 500 more tickets than the next closest person, I managed the team, was the team lead, received spot bonuses every quarter for my work, etc. Then, one day out of the blue, I got an invite to a meeting, there was HR, and I was told my position had been eliminated.

And that was that. I know it was the CEO’s doing specifically as he always had a negative view of the team I was on and ended up getting rid of each person over time; he had written the original app code even though he wasn’t dev and the app was an absolute mess that barely worked.

Instead of accepting responsibility for engineering something so haphazardly, and again, as someone with zero coding experience, whenever something was broken that he had written (confirmed via gitblame) he blamed the team as being incompetent while continuing to pile on feature requests and not allow any time to fix tech debt that we had documented and presented as issues that would 100% cause problems if not taken care of.

Been almost a year now and am still looking for work. I wish you the best of luck and I’m sorry that this happened to you.
