Senior with <2 YOE?

TL;DR I do more than all the senior engineers on my team, both in terms of deliverables as well as ownership. Should I push for a promo with < 2 YOE (I can negotiate it because I have been ticking all senior engineer boxes for a while now) ---- read edits at the bottom I work at a startup that's not very well known. We are a team of about 400 people with 100+ engineers. I'm a frontend engineer and our tech stack is mostly JS and a frontend framework. We have a separate team for UI that writes the markup using HTML/SCSS. #question: is this a problem? I'm not well versed in HTML/CSS as a frontend engineer. I have been promoted once in last 6 months (from L1 to L2, L3 is senior). I might be on track for senior promo soon, but have just ~1.5 YoE. Why I think I deserve the promo? In the past 8 months, I have delivered two very high impact product lines that will have a significant impact on the company's outlook. At the start I was just a junior engineer. But even then I spearheaded all effort for the frontend side for the two projects, all on my own (I wasn't asked to do it), and took complete ownership not just of my own work but across the team as well. I didn't do it for promo, just like taking ownership of whatever I do. My manager has praised me several times not just for my work, but also for my overall ownership of the projects. Most of that may be because of the fact that my heavy lifting has allowed for a lot of breathing space for them :p Should I talk to my manager about it. They might be able to help me with it? #frontend #javascript #tech #promotion #vue Edit1: for those thinking I got played: I'm a workaholic who cant rest well if my work isn't all done before time. If they don't promote me for the next 5 years I would still work the same way. I didn't even do it for promo. I was the same in college as well, always taking 2 more courses than the average student on my classmate. Ended with 20% more credits than what was required for the degree. edit2: I realize that the title itself outside the company has no intrinsic value. I understand that I will barely make it to L3 in Google/E4 in Meta even if I get to senior here. But I'm not optimizing for that as we don;t have big tech where I live; I can move to EU, but cant do that due to personal reasons for the next couple of years at least.
