Architecture patterns, performance optimization, and lessons learned from building production systems at scale.
A client cut their cloud bill from $180K to $95K with hybrid cloud. Here's what I learned helping them migrate (and what you can apply to smaller projects).
I spent $180 testing AI agents on my side project. Here's what I learned about building multi-agent systems on a shoestring budget.
I broke my monolith into microservices and immediately regretted it. Here's what I learned about when microservices actually make sense (and when they don't).
My React app was re-rendering 47 times on every keystroke. Here's how I fixed it without rewriting everything.
I built a GraphQL API that brought down my database. Here's what I learned about N+1 queries, caching, and security the hard way.
Cold starts were killing my serverless API's performance. Here's how I got them from 3 seconds down to 400ms without spending extra money.
TypeScript's type system caught a bug that would've cost me hours of debugging. Here are the patterns I actually use in production.
My queries were taking 8 seconds. I added one index and got them down to 80ms. Here's what I learned about database indexing the hard way.
