Relocating homebase to Dallas for

1. Trading 2. Crypto electric prices 3. Fiber optics

I am only entertaining Principal roles with garden pay involving proprietary trading.

I have my own income from small business. I don't need a job. I also have my first draft of a 500 page Sci Fi ready.

Reclaiming my Russian heritage by learning it while keeping my Spanish brushed up at B2 level. Getting trips planned. I would learn the UK language and explore my blue blood ancestry too but I am native in English. I have lived in 15+ cities all over.

Daytrading at prop firm. Algo trading.

C++ and Rust.

Got my mountain bike fixed for a 110km trail. Learning my knots and lines for J24 sailboat racing. And getting ready to do kite surfing this summer.

Also got my electric violin setup with guitar and harmonica on a killer loop pedal. Just a hobby. Might play for some crowds again. I miss both playing in the symphony and racing the J24 sailboat.
