Hi HN,My first round of performance reviews/salary negotiation in my career is coming up, and I would appreciate any advice from more experienced developers.Current Salary: $95k/yr
Desired Salary: $120k/yrContext: 
I am coming up on a year at a young but decently funded startup in Silicon Valley in the vertical farming space making $95k/yr. I was hired to do imagery analysis and have implemented and deployed deep learning and traditional computer vision algorithms to do imagery analysis. I have had excellent feedback from senior engineers as well as the CEO. I enjoy the job, team, and company, but feel like I have been somewhat missing out financially.I would be very happy with $120k/yr, but am unsure of how I can go about negotiating this. When I was first hired, I asked for $120k/yr but they were rigid at $95k/yr and shut down all negotiation. At the time, COVID was new, I was fresh out of my MS program, and had no proven track record. However, I feel that I have proven myself and could reasonably expect $120k/yr or more at other competitors.How should I go about asking for this raise? I expect that if I ask for $120k/yr, my employer will negotiate me down, which I would not be happy about. On the other hand, I don’t know if starting high at $130k/yr for example would  even be seen as a sane ask that would be a $35k/yr increase. However,  one senior engineer with 4 years of experience told me they were able to negotiate up from $115k/yr to $135k/yr last year.Any advice, paradigm shifts, resource reccomendations, or service recommendations would be greatly appreciated. Thank you!
