Now

Updated: 17 June 2026

I am currently focused on building a strong public body of work around Linux kernel hardening.

Current technical focus

• upstream Linux kernel contributions
• security/keys
• credentials and struct cred
• slab cache isolation
• SLAB_NO_MERGE
• memory-safety hardening
• parser robustness
• flexible array hardening
• writing technical articles
• building JakaHardeningLab

Current professional focus

I currently work as a systems software engineer on safety-critical embedded software.

In parallel, I am building a focused public Linux kernel hardening profile through upstream contributions, technical writing, and practical systems projects.

Current goal

I am targeting Linux kernel / systems software engineering roles with strong kernel teams, especially in:

• kernel hardening
• memory safety
• Linux security
• low-level Linux systems
• security-sensitive infrastructure
• embedded Linux and systems reliability
