Senior backend developer (Rust, Golang) 

Remote work, Russia · $3000 · More than 10 years of experience · Upper Intermediate

More than 10 years of experience with Java, about two years experience in Golang, and a strong beginner in Rust (about 1 year, no commercial code yet, but I am ready to begin).

Java Core, Java SE, Golang, Rust, Git, REST API, SQL, go, Networking, Backend

I'm 37 years old, half of which I work as a software engineer. My top skill is Java SE (14 years or so), and I'm still loving it! At the same time I'd like to develop myself as a developer so I am learning Rust (about a year) and Go (more than 2 years). At the moment I have only done several home projects is Rust (no commercial code yet) and feel myself ready to start looking for a Rust developer job. Code sample by request. Speaking of Go, I finished one project in that language, which was successfully launched in production. That was a web application with Go backend and JS/Angular frontend. As for Java, I worked for two major banks as lead software developer (derivatives, risk management). Former game developer (designed and implemented a Java server for online multiplayer game project).

I'd like to work on server-side code written in Rust (preferred) or Golang. I am considering a remote position only, either full-time or part-time.
