02 fire a request the router, before and after

The intelligent router sits on the hot path of every request. I rebuilt it on Lambda, ElastiCache, EventBridge and CloudWatch. Send it some traffic and watch both versions at real speed.

Simulated. Each latency is sampled around the measured numbers (about 1500ms before, under 300ms after) and played back in real time. More in MA-008.

03 design notes numbered in the order they happened

One note per system, newest first. Dates inside a role are approximate.

If you find a real technical error in any design note, email me. The first person to report each one gets a coffee on me, and their name goes here.

06 standing invitation

I'm always glad to talk about search at scale, latency budgets, event-driven systems on AWS, and getting messy data into clean schemas.

Email is best. Tell me what you're building and what's slow.
