Legacy modernization
Improving existing systems without pretending that a rewrite is always the answer.
About
I’m Seb, a software engineer focused on making complex systems easier to understand, automate, and evolve.
WitzOps is my public engineering notebook for infrastructure, DevOps, AI-assisted workflows, and modernization work.
I work at the intersection of software engineering, DevOps, legacy modernization, and platform thinking.
A lot of my work is about bringing structure to systems that already exist: improving build discipline, making deployment safer, documenting architecture, reducing operational mystery, and using AI tools without losing engineering judgment.
WitzOps is where I publish the public-safe version of that work.
Improving existing systems without pretending that a rewrite is always the answer.
Building repeatable workflows around CI/CD, validation, release discipline, and operational feedback.
Using agents and language models as engineering accelerators, with clear context, boundaries, and review.
Turning self-hosted services into a more deliberate platform instead of a pile of useful accidents.
Making system health, exposure, and change visible enough to support decisions.
Transforming private runbooks into reusable public engineering notes without leaking sensitive details.
