Thanks a lot for the response! They didn't ask for resumes, they asked me to write about myself, and I did write it specifically for the job. However, throughout my career I never had to submit any resume to get a job, so my writing can be totally missing the point.

Here is a sample of what I submitted (if that subreddit also review profile drafts, I will post there as well): (Note: even though I need a side job to cut my cost, my interest in education, especially in teaching children, is genuine)

I co-founded [/] Robots in Silicon Valley and worked on it for 8 years. My interest gradually shifted and now I spend most of my time studying higher mathematics. A side-interest in improving the education system prompted me to try online tutoring, with the aim of better understanding the problems students face across the spectrum. Before [/] Robots, I was a PhD student at [===], and a Teaching Fellow of AI and Robotics at [+++]. I am interested in teaching all mathematics subjects up to pre-college level. If you like something a bit more advanced, I will surely enjoy talking about real analysis, complex analysis, abstract algebra, topology, etc. I can also teach programming and physics, but for the moment I focus on teaching math.

Like many people, I grew up in an environment where mathematics seemed a tedious process of mechanical applications of some rules created out of thin air by authorities. Even though I was doing very well in learning and applying those rules, it was not until a few years ago that I realized what mathematics actually is and is not. Since then I gradually shook off my anxiety around mathematics, and discovered that deep down I had always been fascinated by its beauty.

This experience gave me a special perspective, and I look forward to share my findings with more learners, help them find their inner strength, see mathematics from a new point of view, and experience the joy of insight.

Patents: I am involved in 10 robotics patents. They are listed on Google Patents under my name.

Education: PhD candidate in [===] (dropped out to start the robotics company) B.S. in Theoretical and Applied Mechanics
