Team


Brett Lee — Principal & Founder

I’m Brett, a software engineering leader and strategist based in the San Diego area. Over the past two decades I’ve helped Fortune 500 companies, mid-sized firms, and startups design platforms, scale teams, and navigate industry change.

What I’ve learned along the way is simple: technology only matters if it enables people to do meaningful work. That’s why I founded O’Side Systems — to help startups and small teams cut through complexity, find clarity, and build products and organizations that last.

What I bring to the table

  • Clarity in the chaos: I help founders and teams see patterns, risks, and opportunities others miss.
  • Scalable systems thinking: From architecture to org design, I create frameworks that grow with you.
  • Mentorship and enablement: I coach engineers and leaders so your people scale alongside your product.

My role at O’Side Systems

Think of me as your Fractional CTO and trusted advisor. I partner with you to evaluate what matters, refine your roadmap, and mentor your team, so you can move faster without breaking the foundation.
