Thrilled to share that I’ve joined @datadoghq.com as a Staff Software Engineer on the Language Platform team for @golang.org 🐹
I’m excited to continue my journey in observability and performance engineering, focusing on building tools that make developers’ lives easier.

If you have an interest in understanding garbage collection better, or in how Go's new GC works under-the-hood, I highly recommend reading @michael.express's thorough guide through Go's current and Green Tea GC.

Got feedback from someone I deeply respect. It was sharp, honest, and right. I could’ve done better, and I will.
Pressure and pace aren’t excuses. Just reminders to be more intentional. Raising my own bar again.

I recently spoke at GopherCon UK 2025 about the hidden power of #Go’s `-toolexec` flag. How it can turn every `go build` into a programmable pipeline for things like error-handling enforcement and observability hooks. Here’s the recording:
Unleashing the Go Toolchain - Kemal Akkoyun
The -toolexec flag hides a super-power in the Go toolchain: it lets you turn every go build into a programmable pipeline. In this session we’ll reveal how a simple wrapper command can inject custom…

Second-to-last slot at #GopherConUK25.
ADHD ensured I prepped at the *optimal* time: right before going on stage.
Didn’t enjoy the conference much — probably just tired.
Glad I did it though. The talk… might’ve actually been good.
