Performance Engineering | Real problems. Real numbers. Real fixes.

Performance Engineering Lead with 16 years of experience solving real system problems at scale. I write about what actually happens when systems are pushed hard, latency, load, architecture decisions, and the fixes that worked. Based on real work, real numbers, no fluff.
