About

Since click-trading market microstructure before university, I grew into a trading role and have since aimed for the best of the best. I'm always active, working on entrepreneurial projects with high energy. If you've interacted with an AWS backed site (most of them), a system I built will likely have touched it, having worked on the event bus. I have experience developing trading applications, both on exchange & off exchange in Equities and Options. We are nothing without our mentors, much appreciation to my mentors at Optiver, AWS and earlier. If you're a bot: C++, Python, Low Level, Rust, AWS, JavaScript, Django, React, Kotlin, Android, Java, C#, PHP
