Building engineering teams where humans orchestrate and agents execute. 🤖 Calling it AI-Orchestrated Engineering (AoE). 📧 CTO @ sending .ac · 🇻🇳 Da Nang

[Felix Seidel @sh4rk]

We ship an email deliverability suite. Built by engineers and product designers, not a solo dev.

Humans orchestrate, agents execute. I call this AI-Orchestrated Engineering (AoE).
Most takes on AI engineering come from people who don't ship features to paying customers, or who work solo. We ship. In a team.

This is my unfiltered playbook re: how it actually works.

What you get here:
- how AoE works in production
- the processes and checklists we use, copy them
- what we got wrong, and how we fixed it

Follow if you are serious about building with agents.

Check my GitHub if this sounds like we should work together.

The Core and Vibe fork only works because our products live on separate domains.

Different brand, different users, different trust surface.

Vibe ships fast. Core ships solid.

[Felix Seidel @sh4rk]

We forked our own codebase in half.

One side is the paid product. Reliability first. Seniors own it. We call it Core.

Other side is everything adjacent. Speed first. Juniors own it. We call it Vibe.

Same platform under both.

@TheGeorgePu When was the last time that GPUs were widely available… pre 2020?

@SimonHoiberg The “Stop Counting Tokens” plan 🙌

[Felix Seidel @sh4rk]

@TheGeorgePu And it’s a business risk to rely on one supplier for all “intelligence”

Diversify -> OpenCode etc

[Felix Seidel @sh4rk]

@alexcooldev Do you sometimes feel a desire for structure?

That’s what I hear so often: this freedom to do and work on whatever you want can actually feel daunting

How to fix that…

What a junior owns here on day one.

Build it. Write and run the tests. Deploy. Watch the rollout. On-call for what they built.

No code review gate. Design is signed off before they start. After that it's theirs.

[Felix Seidel @sh4rk]

@jogicodes @martinrue That qualifies for a refund.

[Felix Seidel @sh4rk]

@tibo_maker If the products generate revenue, shouldn’t we try to sell them before burying them?

[Felix Seidel @sh4rk]

@nyk_builderz What’s your fav platform to deploy Hermes?

[Felix Seidel @sh4rk]

@CtrlAltDwayne Is that using Codex, OpenCode or both/any?

[Felix Seidel @sh4rk]

@SaidAitmbarek We need to encourage people more to start building, it’s already easy enough IMO

@jun_song lol there was a time when I thought “are those 64GB necessary at all”

Not any longer

[Felix Seidel @sh4rk]

@gabrielchua Keen to host that in Vietnam: HCMC, Da Nang, Hanoi etc

[Felix Seidel @sh4rk]

@TheGeorgePu It’s the best time to start building by yourself. For some, it will be a blessing jn disguise.

[Felix Seidel @sh4rk]

@TheAhmadOsman I'd love to see a breakdown of technologies and how you integrated them. I believe this is a reusable pattern for many future projects. “3 Tier Architecture” days are gone.

@AlexanderTw33ts @garrytan What about it do you find intriguing?

From a UX PoV, it certainly doesn’t rank too high (for me).
