            <p>
              I aim to optimise maintainability of software while modelling the underlying domain of a business.
              Understanding the context is crucial to solving real problems for real humans. I lean on
              philosophies like Domain-Driven Design, DevOps, Continuous Deployment, and Extreme Programming.
            </p>
            <p>
              Lately I'm digging into HTMX, event sourcing, and reading the PostgreSQL manual. I've used Linux
              for 10 years and currently run NixOS on my personal machine.
