18:00 Will Agentic Coding Make Us Dream of Electric Sheep? by Sebastian Ware
LLMs had a major breakthrough in the autumn of 2025 when code generation capabilities suddenly allowed the creation of complex software applications with limited or no human review or correction. This has on one hand been hailed as a coding revolution and on the other hand criticised as another step in the enshittification of software development. Applications such as OpenClaw and Moltbook proved both points. Vibe coding has become a magic wand for low effort builders who are in the business of selling dreams, but agentic coding isn't just for fairytales and pixie dust.
I have spent all my working hours since the release of Opus 4.5 exploring human-in-the-loop agentic coding by building tools* to assist with real world software development tasks. I have used these tools to maintain existing code bases, build server infrastructure, created desktop GUI-applications and shipped code to half a million users.
This talk will explore enshittification, safety and developer happiness: the transformation from software developer to software builder; how following a PITA**-loop improves outcomes in a major way; and why a team of five replacing a department of 50 should be about reducing friction, not downsizing.
---
* Tools combining context engineering (Anthropic), (context augmented) automatic prompt engineer (APE), Just-in-Time Retrieval and RAG
** Plan, Implement, Test, Analyse (PITA)
NOTE: electric sheep in this context refers to cheap, low quality software that mimic the real thing.

19:00 AI that builds(?) systems by Simon Velander
In the future, AI will build our IT systems! It is an increasingly common observation, but at the same time many solutions seem to be replaced by AI rather than built by it. In this talk we dive deeper into this question. We invent a completely neural full-stack solution and invite you to reflect on the hypothesis that traditional software will not eat so much of the world?
20:00 For those who wants to keep going,
follow us to a pub nearby for a last beer.

Looking forward to seeing you!

SPEAKERS
Sebastian Ware, Fullstack builder
Sebastian Ware learned to program at 8, studied CPU and OS design as a hobby at 15, and wrote his high school thesis "Transputers and Parallel Programming" in 1993. He then took an unexpected detour into marketing and product development working with clients like Absolut Vodka and Chalmers University of Technology before co-founding a wine import agency. These experiences gave him a builder's perspective that would prove invaluable later.
He returned to software development 20 years ago and has since shipped code across backend systems, web applications, and mobile apps to half a million users. Since the release of Opus 4.5, he has gone all-in on human-in-the-loop agentic coding, building tools that combine context engineering, automatic prompt engineering, and RAG to tackle real-world development tasks. He is currently working on nix-infra, AI-assisted open-source infrastructure orchestration, and Veckoappen, a Swedish calendar app with 500k users.
