Performance optimization

Page speed gets visitors through the door. Performance keeps the whole system responsive once they are inside: searches that return instantly, checkouts that never hang, and admin screens your team can actually work in.

I profile your application end to end and fix the slow parts: database queries that scan too much, API calls that block each other, and background jobs that pile up. This work matters most for stores and platforms where a slow system directly costs money.

The payoff is a site that stays quick during your busiest hour, which is exactly when speed earns you the most.
