I'm a senior embedded software engineer with 7 years of experience in safety-critical and security-sensitive systems across Aerospace and Automotive. I've worked across the full development lifecycle — from architecture and implementation through verification, certification support, and security analysis.
I work best in environments where precision matters: high-integrity software, tight process requirements, and real engineering challenges. I'm comfortable working as a specialist resource within larger delivery teams, and I understand the documentation and traceability demands that come with certified development.
Fredstam Consulting is available for project-based and retainer engagements — whether you need a specialist to lead a critical sub-system, support your team through a certification effort, or conduct a focused security review. Engagements can be remote or on-site across Sweden and remote worldwide.
