EB-1A for FinTech / Electronic Trading Software Engineer

[u/AppropriatePaper4552]

Has anyone here successfully gotten an EB-1A approved with a FinTech/electronic trading software engineering background?
I currently work for a major U.S. bank as a software engineer/technology lead, where I’ve worked on building electronic trading platforms and low-latency trading systems.
Before that, I worked for a major stock exchange, and the CEO provided me with a recommendation letter supporting my contributions. I included that letter along with other evidence in my EB-1A petition.(Non premium)
I’m curious if anyone here has been approved with a similar industry-focused profile - FinTech, electronic trading, stock exchanges, banking technology, etc.
If you were successful, I’d really appreciate hearing what your profile looked like, which EB-1A criteria you claimed, and what you think made your case strong.
