The best developers don't just write code; they also draw. Whether you're building features, debugging systems, or explaining ideas to teammates, great architecture diagrams can make the difference… Why great developers draw: 4 architecture diagrams that clarify everything

Why great software developers draw 🧠✏️

At #AIMHDC2025 I shared 4 diagrams every dev should know:
🧩 Sequence
🔄 Flowchart
🏗️ Class
🗃️ ERD

Because seeing the shape of your idea can be the difference between being heard & being understood.

AI code completion is yesterday's news. Today's rise of AI coding agents, which are tools that autonomously generate, test, and even refactor code, raises a critical question: Will engineers become… Will AI coding agents replace software developers?

I gave this talk at Heartland Developers Conference 2025 last week:
🎤 Will AI coding agents replace software developers?

AI isn’t replacing developers overnight. It’s changing what it means to be one.

When priorities are unclear, engineers stall. I shared how we’re tackling this at @fleetdm.bsky.social + what you can do, too.

A guide to balancing focus and efficiency when working with AI agents, including tips on single-tasking vs multitasking Full article:… Multitasking with AI agents: When it works and when it fails

🤖 Can AI agents really make multitasking more productive, or is it just a trap?

We broke it down in this video: when to single-task, when to multitask, and how to keep your agents on track.

A personal story of how organizational dysfunction nearly broke me, and how transparency transformed everything. Learn why visibility matters more than process, meetings, or roadmaps. Full article:… Why transparency beats everything else in engineering

Still one of my biggest lessons in engineering leadership:
Without transparency, even the best teams drift.

Make priorities visible. Make blockers public.
Everything else gets easier.
