You've graduated from 'the new person.' You're the one fixing the tricky bugs, explaining how the codebase works to newer devs, and actually understanding why things were built the way they were. Your resume needs to reflect that growth—you're not entry-level anymore.

Common Mistakes Full Stack Developers Make
❌ Mistake
Still listing only technical tasks without impact
✓ Fix
'Built API' is boring. 'Built API that handles 100K requests/day with 99.9% uptime' tells a story.
❌ Mistake
Not showing leadership signals
✓ Fix
Even without a title, you're likely mentoring, reviewing code, and influencing decisions. Make it visible.
❌ Mistake
Underselling scope and complexity
✓ Fix
You work on harder problems than freshers. Highlight the complexity: scale, reliability, security considerations.

Frequently Asked Questions
When do I become a senior full stack developer?
It's less about years (typically 4-6 total) and more about capability. If you can own complex features end-to-end, mentor others, and make architectural decisions, you're approaching senior.
Should I learn more frameworks or go deeper?
Go deeper. Being an expert in one stack is more valuable than being mediocre in five. Add adjacent skills like DevOps and system design.
