Who I Am

About Marcus

I'm a senior embedded software engineer with 7+ years of experience helping teams in regulated industries deliver certified, compliant systems — across Aerospace, Automotive, and safety-critical domains more broadly. I've worked across the full development lifecycle: architecture, implementation, verification, certification support, and security analysis.

I work best where the stakes are high and the process demands are real.

My value to a team isn't just technical — it's knowing how to navigate the standards, structure the evidence, and keep a certification or security review on track. I'm comfortable operating as a specialist resource within larger delivery teams, and I understand what it takes to get a compliant product across the line.
