Positions he holds, in one line each (details on the State of AI page): an LLM is a tool and everyone should use one, treated as a draft to check; the model is no longer the bottleneck, the codebase, harness and review are; most applications should be modular monoliths, not microservices, and most don't need Kubernetes; statically typed languages matter more with coding agents, because the compiler is the cheapest deterministic feedback loop; where a model runs is decided by the data class, not by preference.

## Blog posts

- [Engineering mindset in the age of AI](https://laszlonemes.com/blog/engineering-mindset.md): AI took the typing, not the engineering – and the thinking is now the bottleneck. What that mindset is, how its absence looks (tool faith, green tests and red prod, best practices without their context), why AI repriced every trade-off, the difference between simple and naive, and what a junior loses when the consequences land on someone else. With migrations, three pods and an Excel export, in .NET and Java. (September 26, 2026, 27 min read)
- [Shadow AI and local AI: the data class decides](https://laszlonemes.com/blog/shadow-ai-local-ai.md): It isn't local versus cloud: there are four levels of control, and the data class picks one. The arithmetic of running models locally, why local carries the burden of proof, the LLM provider as an adapter, what an EU region does and doesn't give you – and why shadow AI is a product problem, not a disciplinary one.

- [Loop engineering is a control problem](https://laszlonemes.com/blog/loop-engineering.md): What people mean by "loops" around coding agents, why the version that works in a team is a fifty-year-old control loop with an agent as the actuator, and how to build one from a linter, a cron job and pull requests.

- [Two kinds of micromonolith](https://laszlonemes.com/blog/micromonoliths.md): Microservices and Kubernetes are scaling and organisational tools, not quality tools. What splitting an application really costs, why the modular monolith is the good micromonolith, and how to build one that scales without either. (September 20, 2026, 18 min read)
- [Git and GitHub: the mental model, in pictures](https://laszlonemes.com/blog/git-and-github.md): Almost every git confusion is a missing picture, not a missing command. The pictures: snapshots, the three areas, branches, remotes, pull requests and undo – with VS Code as the daily driver and the commands beside every button. (September 20, 2026, 18 min read)
