I help teams build software that keeps shipping as complexity grows.
I'm Hans L'Hoest. I collaborate with engineering teams to align strategy, architecture, and delivery, and work hands-on to research and build products. Roles: Fractional Architect for teams and Software Product Engineer for co-creation.

This post captures my current thinking on how LLMs are impacting software development, particularly around software quality and engineering discipline. My main observation: most of the best practices we've relied on for years are just as important—maybe even more so—in an LLM-ass…
