In 2026 one of the skills that every software engineer, developer or architect will need is the knowledge of quickly identifying the root cause in (unknown) code.

This will be a differentiation factor, as more and more code will be AI generated and developers will not know all portions of the code.

Being able to visualize the data flow and/or the code flow in your head will proof you to be human and show that your brain is still more capable than any AI coding assitent.

Experience and mistakes matter - they set you apart from what's happening in our industry.

@maishsk safe travels

Still thinking about it: the best tech events aren't about the tech. They're about the people who show up, share honestly, and lift each other up.

Thank you to everyone who made this one special 🙏

A little recap from AWS Community Day DACH in Berlin 🧵 (1/5)

@AWSCommunityDE #BuildInPublic

(2/5) The 7am setup team. Nobody sees it, but settings things with the team is one of my favourite parts. Community is a verb.

(3/5) Fantastic sessions including two Keynote Hall sessions on trusting AI agents in production — Anton Babenko on the Terraform Trust Gap, Christian Bonzelet on shipping agentic engineering at scale. Both landed hard.

(4/5) The AWS Community Builder Meetup. So many curious, generous people. If you're on the fence about becoming a CB — do it. 🙌

(5/5) And a day with fellow AWS Heroes to top it off. I'm heading home with a full notebook and a fuller heart. Thank you, AWS Community. ❤️

Grateful doesn't quite cover it. Being an AWS Hero means learning from people who are ridiculously good — and who still make time to share it forward.

Funny how a day with peers reframes everything. Walked in with 3 problems, already have 3 new angles to try.

This is why community > going it alone. Every time. ❤️

The best thing about Heroes day isn't the talks or presentations...it's the discussions. The unfiltered "here's what actually broke for us" conversations you never get from a stage 🔥

Great minds, good coffee, better conversations incoming. What would you ask a room full of AWS Heroes? 👇
