Your SQL is slow. You think it's the database. It’s actually your query. Use EXPLAIN. Stop guessing. 🧐 #SQL #RDS #Performance.

Best way to debug legacy code? Comment out random lines and see which ones crash prod. Science. #DebuggingTips #LegacyPain #DevJokes.

Hot take: Adding more comments won’t fix bad code. But writing better code can eliminate the need for most comments. ✍️ #CodeQuality #ProgrammingTips.

Don't use RDS default settings in prod. Change:.🔧 Backup retention.🔧 Multi-AZ.🔧 Monitoring. Unless you enjoy surprise downtime and no backups 😅 #RDS #AWSProdTips #InfraTips.

S3 is awesome until you realize someone set your prod bucket to public and now Google is indexing your private reports. Oops. #S3 #SecurityFail #AWS.

Don’t debug a failing Docker container with guesswork. Use this:.```bash.docker logs <container_id>.```. Or for real-time logs:.```bash.docker logs -f <container_id>.```. You're welcome 😉 #DockerLogs #Debugging #DevLife.

A 10x dev who doesn’t write docs, test code, or attend standups isn’t a 10x dev. They're a solo act in a team sport. #TeamDev #SoftwareEngineering.

Debugging a legacy system taught me one thing: never judge old code. You don’t know what wars it survived. #RespectTheCode #LegacySystems #DevWisdom.

You know your onboarding docs are solid when a new dev finds a bug in prod and fixes it *on their second day*. That happened today. Proud moment. 💙 #Onboarding #DevEx.

True story:.We once missed a critical alert because someone filtered Slack on 'Do Not Disturb'. Now alerts go to a special channel AND call the on-call via Twilio. 🚨📱 #OnCallLife #Monitoring #IncidentResponse.

S3 + CloudFront is fast… until you forget to set Cache-Control or CORS headers and your users get stale or broken content. Been there. #S3 #CloudFront #DevTips.

Drive-by refactors in your PR? Don't. I’m here to review your feature, not guess why you rewrote half the auth layer. #CodeReview #BestPractices.

Documenting your internal APIs well is like writing a love letter to your future team 💌. Or a breakup note if you're leaving. Either way, write it. #APIDocumentation #TeamWork.

What’s the weirdest thing you’ve stored in S3? I once saw a team push video surveillance footage and an entire Django admin export in the same bucket. #S3 #CloudStorage #DevConfessions.

The real 10x developer makes everyone around them better. They don’t need a cape, just context. #DevEx #Mentorship.

I've worked with '10x' devs who couldn't review a PR without starting a war. Net productivity: -3x. #EngineeringCulture #TeamWork.
