About Seijaku
Hi, I'm Luke Fitzsimmons, and through Seijaku, I help good people do better work by bringing calm, competent IT support, clear security guidance, and operational clarity to their organisations.
For over 25 years, I've worked across enterprise, education, healthcare, and government. My background spans infrastructure, networking, cloud services, security, and leadership. I'm certified in ethical hacking and Python, and trained in people management and mental health first aid, because IT is just as much about people as it is about systems.
Through Seijaku, I offer steady, senior-level help to teams that need things to work and keep working. That might mean modernising old systems, closing security gaps, solving tough problems, or just figuring out what matters most right now.
I tend to work best with small organisations such as schools, clinics, not-for-profits, and ethical businesses where the stakes are real and the work matters. If that sounds like the kind of support you're looking for, let's talk.
