These days I'm a project maintainer leading a team of F# and Rust developers, and looking to expand this team (and hire Linux DevOps specialists and/or build engineers). Get in touch if you want to know more.
If you're interested in my technical background, read below:
In the low-level front, I've used Assembly, C, C++, and starting to learn Rust (could maybe give a go to D too).
When I was freelancing, I was willing to learn Elm in case I needed to do some web+frontend development and they didn't let me write TypeScript in strict mode (plus tslint), or Gleam in case I had to interoperate with any BEAM-based language, or Ceylon/Kotlin/Frege (along with ParparVM if iOS is needed) or maybe Swift, in case I needed to implement mobile apps and they didn't let me use Xamarin.Forms+F#.
In regards to databases, I'm an old-school guy who thinks normalized data usually beats any NoSQL/NewSQL solution, except for rare BigData indexing/denormalization scenarios.
