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.

Because one talk over a weekend apparently wasn’t enough bad life choices:
Also on Sunday, 12:30–13:10 in H.1301 (Software Performance devroom) I’ll be speaking with Augusto de Oliveira: “How to Measure Software Performance Reliably”

On Sunday, 13:30–14:00 in UB5.132 (Go devroom) I’ll be co-presenting with Hannah Kim:
“How to Instrument Go Without Changing a Single Line of Code”
Basically: all the ways to get observability without touching your beloved git blame.

This past week I used my R&D week at @datadoghq.com to build a WASM transpiler that generates Go (ARM64) assembly code.
It's not publicly available - I want to rebuild it from scratch - but I can tell you that it works!

I'm looking for a PR review tool dedicated and native to macOS. I tried tools embedded to VS Code, but I didn't like the experience.
I want good UX and standalone app (so that I can track how much time I spent reviewing code).
Any suggestions?

@deadprogram.com I would love your opinions on this 😊
A bit more context: I have libraries written in other native languages that I want to expose from a Go package/module. Today, there are basically two ways to do this:
1. CGO and link against those libraries.
2. purego (e.g. github.com/ebitengine/p...) and dynamically load them.

Does anyone know someone attempted to transpile WASM to Go ASM? Or similar?

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.

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:
