Good Old Lion

Software that works. AI that pays off. Systems that stay safe.

Independent engineering consultancy. I help small and mid-sized teams build reliable software, adopt AI where it actually saves time, and keep their infrastructure secure — hands-on, from first conversation to production.

How we work

  1. Conversation. A short call to understand the problem, constraints and what success looks like.
  2. Proposal. A written scope with clear deliverables and milestones — no vague retainers.
  3. Delivery. Iterative work with regular demos. You see progress every week, not at the end.
  4. Handover. Documentation, knowledge transfer and optional ongoing support.
