Johannes "Lockhead" Koch

In his keynote @werner.social social said „Now go build“ and as we take Bias for Action serious, we built listen-to-the-heroes.com. Thanks @hoegertn.de @pgarbe.bsky.social @osterjour.bsky.social @abjoerne.bsky.social @monica.aws-he.ro for making this possible!

Every internal tool ends with "the one person who understood it just left." Is a platform an asset or a bet?

Is the scary part of a deploy the code, or the fact that only one person really understands the rollback?

We keep asking if AI will replace developers. Isn't the quieter question what it's turning the job into?

Is the hardest part of AWS the engineering, or deciding which three of the forty services you actually need?

One thing I did not expect while prepping Pegasus Galaxy for real players: I built AI agents that can play it, and they immediately burned tokens ;). Agents as adversarial testers for your own game is a weirdly effective way to find the holes. Would you trust AI players to balance-test your game?

Does your developer portal save time, or add one more place to look before you give up and ask in Slack?

We ship faster than ever. Are we shipping better, or just making mistakes with lower latency?

If anyone can ship with AI, is the moat still the code, or the taste to know what's worth shipping?

Infra as code promised repeatability. Why does every environment still feel a little bit handcrafted?

If a platform needs a dedicated team to explain it, is it reducing cognitive load or relocating it?

Is a green build proof it works, or just proof nothing we thought to test is broken?

Is your bottleneck in 2026 the model, or the harness of context, memory, and tools around it?

I hope to see a few of you on Monday at the #AWSUserGroup in Bensheim https://lckhd.eu/E4gQIw #awscommunity

We automate the happy path beautifully. Why does the 3am incident never follow it?

Golden paths are great until your use case isn't on one. Then is the platform helping, or in the way?

Is "promotion" in your pipeline really promotion, or a rebuild you're hoping comes out identical?

I enjoy installing the latest software, but #Kiro now ships multiple times a week for the #KiroIDE. Each update costs 2-3 minutes, and I have to check no agents are mid-task first. Maybe I should move more to #KiroWeb? How do you solve that?

Would you kick off a real task from your phone and trust the agent to run it while you're at dinner?

We're starting the next round for Pegasus Galaxy tomorrow morning - let me know if you have a few minutes to sign up and play around with it a bit Ticks will start at 8am UTC Register now: https://lckhd.eu/eGIq0b Ping me so i can invite you to our testing chat :-)

Is "lift and shift" a migration strategy, or just moving the problem somewhere with a meter running?

Is the best platform team the one you hear from constantly, or the one you forget exists?

Conference season is loading. Two talks at CLC Mannheim next month, then a Code Talk at re:Invent. Platform engineering, LLM cost reality, and onboarding a service live on stage. Which should I post most about while I prep?

Now live at the AWS User Group Mannheim: Armin speaking about EKS Auto Mode after I gave an overview on the #AWSCommunity programs 🥳 Having fun and great pizza 🍕 #awsmannheim #awscommunitybuilders #awsheroes

Backend and frontend: do they release together, or on their own schedules? And did you choose, or inherit it?

If an AI could remember one thing about your project between sessions, what would you want it to be?

Did the cloud make us faster, or just better at building things we'll have to pay for forever?

Is "platform as a product" a mindset, or a slide we show once and never fund?

We test our code relentlessly. When did we last test the pipeline that ships it?

The agent is always confident, even when it's wrong. Is the new skill knowing when to doubt it?

Did multi-account, multi-region really buy us resilience, or just a bigger surface to misconfigure?

Does your platform make the right thing the easy thing, or just the only thing?

Every team has one pipeline step nobody dares touch. What's yours, and when did it become untouchable?

Is high deploy frequency a sign of health, or just a metric we picked because it's easy to count?

Looking ahead: these two weeks were how I build (KiroCrew) and how I ship (two CI/CD shapes). Next, based on your replies: multi-account pipelines, a proper battle-test of KiroCrew, and finally fixing my promotion model to package-once-promote-many. #BuildInPublic #Kiro

Is the real skill in 2026 writing code, or knowing when to doubt the thing that wrote it?

Closing out two weeks of building in public. Honest lessons: The posts where I owned a gap got more engagement than any polished win. "Harness > model" struck a nerve. And almost everyone admitted to a pipeline hack they're quietly ashamed of. What should I go deeper on? #BuildInPublic #DevOps

Most of our workloads are as predictable as a Monday. Are we paying for elasticity we never use?

Is a great internal platform something you notice, or something you only notice once it's gone?

The unglamorous parts of my pipelines are the ones I'm proudest of. A manual migration guard. A hack I'm not proud of. A promotion step I know isn't right. None of it pretty. All of it ships. What's the ugly-but-reliable hack you're secretly proud of? #BuildInPublic #DevOps

If AI writes the code, reviews it, and tests it — whose code is it when it breaks at 3am?

Letting AI write made me a better reader and a worse writer of code. Fair trade, or a skill I'll miss?

Two weeks of building in public, in one place: KiroCrew: https://lckhd.eu/AmGz5I CI/CD, two pipelines: https://lckhd.eu/Wa8qJd CI/CD refresher: https://lckhd.eu/PUBefo Build + ship. Which one's for you? #CICD #Kiro

Is a half-followed Well-Architected framework safer than none, or just confident enough to be dangerous?
