Mike Zornek, looking for work. @mikezornek.com · 08/09/2026
💜 A favor to ask: I'm looking to land Elixir consulting work. To help get in front of new faces, I have a "one problem, two weeks, $6,000" offer. Aimed at one nagging thing: a flaky test suite, a stalled upgrade. The debt that falls on the floor. A share or an intro would mean a lot. 🙏 #ElixirLang

Trying something new. I’m turning my two-track agents article into an animated explainer video. Writing a script, syncing with images, animations... It's hard! 😱 Hope to share the result soon.

Instead of running ten agents in parallel, I use only two. And that works really well for me, so I decided to share why and how. tidewave.ai/blog/two-tra...

You don't need ten agents. You need two tracks.
A practical two-track workflow for using coding agents in parallel: write specs with one agent, then let another implement them.

It’s hard to collaborate with Claude Code on writing. Too much copy/paste. I wanted something like Google Docs for the agentic. So, I used Tidewave to build a local Markdown editor where I can connect Claude Code and we can work together. Would you use this?

Tidewave is the first AI tooling pitch in a while that sounds like it understands the actual job: not just reading code, but running it, querying data, and checking logs. If it works as advertised, that’s a meaningful step up from autocomplete with branding.

I use LLMs to audit my code a few times a week now. Below is the prompt I use most often. It's super simple, runs in less than 30min on a medium codebase, and gives you actionable suggestions for how to improve performance, data integrity, or security in your codebase. #ElixirLang
I'm building {insert purpose of your application}.
I want you to do an adverserial review of the codebase
Please run one subagent per file and per focus (performance/security/integrity).
Write your findings to `docs/audit/(performance|security|integrity).md`.
Give each finding a unique identifier in its header.

I was able to wire up Popcorn to run Elixir and PGlite to run Postgres, both in the browser. This means we can have an interactive and safe sandbox for arbitrary code. Which means a really good experience learning Ecto on a website. I'll publish it soon :) #ElixirLang

The workflow I use to ship production software with AI coding agents. Not 10 agents in parallel. Just 2. One implementing a feature, one prepping the next. Coordinated through Tidewave's task board. I built Elixir Radar's newsletter system in a week this way. www.youtube.com/watch?v=A1_L...
