Backend Software Engineer
Rizky Kurniawan
I'm a backend engineer based in Indonesia. For the last four years I've designed and shipped production APIs and services in .NET, Go, and Node.js, and I've been building more in Rust lately.
I care about the unglamorous parts: clear data models, systems that keep working under load, and code the next person can actually read. This site is where I write about that and keep a running record of what I'm building.
Open to remote backend roles, and occasionally available for freelance work and 1:1 mentoring.
