I suppose I should get started on making something that I can own.
Level 1: There's a basic web site. Think of it as fizz buzz. I can see you have a basic sense of style -- web site aesthetics, code quality, etc. You don't need a lot, but what's there ought to be sane, sensible, and good.
Level 2: There are a few awesome things on it. Something clever, or something which shows some technical prowess.
It can't really hurt; if it's not fancy, I'll assume you didn't have time. If you have typos, blink/marquee tags, and syntax errors, I'll pass. But the more information you bring to the table, the better.
Right now, what people know about you is you passed a few reasonably rigorous interviews -- Tesla and Uber. Given you passed those, you'd likely pass more technical interview too (which is not the same as getting a job offer). Weaker companies might hire based on that. Stronger wants will want more signal. Anything you can do to generate that signal will help.
As a footnote, you included the line "I developed tooling for real time data through graphql subscriptions and grpc streaming. I built a protobuf to graphql schema generator tool. I have extensive experience with React hooks and making Redux-less applications. I was on the Uber Elevate team and brought several applications from 0-1." Put that in you linkedin.
There's a hierarchy I use when I look at resumes:
1) Weakest: Applicant worked somewhere. ("I was a software engineer for bagels.com")
2) Weak: Applicant worked on / with something. ("I worked on the customer database for bagels.com")
3) Average: Applicant accomplished something ("I increased the performance of the customer database of bagles.com by 25%, saving the company $50k/year in server costs and reducing latency")
4) Strong: Applicant accomplished something which justified their salary ("I rewrote the Fortran applicant database of bagles.com in node.js, moving it from a mainframe to AWS. This resulted in 25% higher customer conversion rates, and saved $500k / year.")
5. Strongest: Applicant accomplished something clever and technically impressive ("I built a pipeline which could render photorealistic bagle sandwiches for bagles.com prior to customer orders. This increased customer conversion rates 5x. I used [insert set of technically impressive techniques].")
The higher up you go that chain, the more likely you are to get the job you want.
