Recently fired/quit from startup, trying to come up with a plan

A year ago i was hired as a data scientist in a very niche field at a pre-revenue start-up. i hated the job i had before, and this field meshed well with my background (i have a BS in biomedical engineering, which was related to this company’s value prop). i lived in Seattle (very expensive), but i took this new job for a low salary and a good amt of equity, with assurances that things would pick up and i would get a raise soon...

well almost a year passed, and i was still making the same amount. i wasnt doing any actual data science, just building cloud architectures and writing Json parsers. i got super burnt out and unproductive, my boss confronted me, i told him i was thinking about leaving. we worked it out, but then not too much later he fired me since we were really starting to get close to running out of money. it sucks cause i was very close to getting my equity, but whatever, things werent looking great over there anyway.

now im faced with the job market: I dont have a degree in CS, but i can write decent python, understand general ML and data science best practices, and i am taking a Coursera on DS&A with c++. the coursera is attached to an online masters in CS program, i.e. i do well in this course and pass an online exam and i can maybe get into that masters program in 2020.

problem is, i need a job SOON. i have loans in my parents name, a GF w very traditional parents, and too much pride to collect unemployment for 6 months. ive started talking to recruiters, but i feel like without a better portfolio (mine is outdated and not very good) or DS&A understanding, im just not ready for the market in Seattle.

so, my question is, what should i do with my unlimited free time, previous experience, and somewhat limited financial resources? i dont want to go to a bootcamp... Does anyone have any tips for a self-study program that can get me into a high-paying data science/engineering, or SDE/SWE role within the next 3 months? i dont know shit about front-end and im only okay at SQL. i only have like 50 on LC, but i want to buckle down on it more starting now. ive been fired for a week and i need to do SOMETHING. im willing to work 10+ hours a day. should i stick with DS roles and head over to Kaggle? or pivot to something more attainable for someone with just a BS, like SDE or data engineer?
