Developer / Architect

I'm an old guy with 40y of programming experience (freelancer/self-employed) and very crypto affin. Since I'm tired of all the usual non-crypto projects I worked for, I'm looking for an outcome while doing some job in a crypto environment. I already got basic experience with crypto programming, but I'm not a specialist yet. My main programming languages so far have been C# and C++, but I already used JS, TS etc. too, even some Solidity and Rust for testing purposes. I'm of german nationality, but living in Switzerland. Remote would be welcome. Serious enquiries are welcome!...
