Hi, I’m Alexander 👋

I specialize in low-latency, high-scale production systems.

Teams bring me in when:

  • Latency is measured in seconds and needs to be measured in milliseconds
  • p99 is hurting real users
  • Systems collapse under real load
  • Performance issues start costing customers

Recently, I:

  • Led a competitive performance turnaround, moving from slowest to lowest latency among the top AI gateways and eliminating performance-driven churn
  • Served as primary technical lead for multi-region enterprise rollouts handling 30K–50K+ RPS
  • Reduced infrastructure by 38% while increasing scale capacity
  • Built production profiling and validation systems that reduced performance incidents by ~70–80%

I focus on the bottlenecks that survive conventional optimizations.


I enjoy building and contributing to open source software.
