Technical Tip
ā” Stop storing sessions in your database.
Use Redis instead.
Database sessions = slow queries + table locks + scaling nightmares.
Redis sessions = microsecond reads + horizontal scaling + built-in TTL.
If your app has more than 1,000 active users, this matters.

For Founders/Clients
š” Hiring a developer? Ask these 3 questions:
"How would you handle 10x our current traffic?"
ā If they have no answer, they've never shipped at scale.
"What would you NOT build in the first version?"
ā Good developers cut scope. Bad ones say yes to everything.
"Show me something you built that failed."
ā Experience lives in failures, not portfolios
