Hello Dev.to — Lessons from Systems That Worked in Dev (and Failed in Prod)

Hi everyone 👋
Glad to finally join the Dev.to community.

I’m a backend-focused software engineer with 15+ years of experience, mostly working on APIs, databases, and production systems.

Early in my career, I believed that if something worked well in development, it was “done.”
Production quickly taught me otherwise.

Over the years, I’ve seen the same patterns repeat:

• APIs that work fine in dev but slow down in production
• Databases becoming bottlenecks as data grows
• Issues that aren’t bugs, but missing assumptions
• Monitoring added only after users complain

These experiences shaped how I design and review systems today.

What I plan to write about here

• API design and production readiness
• SQL performance and common real-world mistakes
• Backend and system design lessons
• Why dev success doesn’t always translate to prod stability

My goal is to share practical, experience-driven insights — not theory, not hype.

Looking forward to learning from all of you and contributing where I can.
If there’s a topic you’d like me to cover first, I’m happy to hear suggestions 🙂

Thanks for the warm community 🙌
