I've been working in IT for 4 years now in various roles at IBM. These roles included, in order

1. Business analyst (tester) - worked with devs to write user stories and functionally test their code
2. Agile Scrum Master - led a small dev team (2 devs & 1 analyst) through a year of software releases and production support.
3. Security Engineer on a small Blockchain proof of concept (10 month gig) - me and another guy implemented security controls and also had the opp to write some JS on the Blockchain since it was a small team. This sparked my passion for web dev.
4. Application developer for 15 year old Gov't system (past 10 months). Mostly doing server maintenance and patching (ssh, linux commands), very little new code being written and using ancient tools / stack. Also very little learning. Certainly no html, css, or js.

Starting January 30th 2020, I began self-teaching and implemented a daily practice in HTML, CSS, and then eventually JS. My goal is to land a front-end developer role sometime in February 2021 when this Gov't contract ends.

I realize I have about zero work experience using these front-end technologies and so I'm planning on applying to Junior Dev positions rather than Senior, but I'm afraid I'll have to lose my 110k salaray (I live in DC metro area) for a 60-70k starting salary that's typical for new developers.

Do you think I'm in a position to negotiate something around 100k given I do have "relevent" software development experiene over the past 4 years, even if it's not with HTML, CSS, or JS?
