Mentor of record
Montree Saelim
Performance coach for ad-tech pipelines; insists on honest regressions.
Cohort notes
“JSON encoder lab mirrored our tagging hot path—mentor refused micro-opts without numbers, which stung then helped.”
Straight answers
Hardware?
You profile on your machine; we discuss thermal throttling honestly.
Results guaranteed?
No. You learn measurement; wins depend on your codebase.
Excluded?
Kernel bypass and eBPF deep dives are not covered.
