Why I Stopped Calling Myself a Full-Stack Developer

👨‍💻 Sergio Lema shares a thought-provoking perspective: the “Full-Stack Developer” label often hides the real value engineers bring. Instead of being defined by frameworks or languages, he reframes himself as a Feature Expert — someone who masters recurring problems and patterns across systems.

🔑 Key Context from the Article
Beyond the buzzword → Full-stack has become a catch-all term, but true expertise lies in solving complex problems, not juggling syntax.

Feature Expert mindset → Focus on logic, architecture, and data structures that repeat across projects (search, auth, pricing, caching).

Real-world examples → Pricing systems, search optimization, caching strategies — these challenges look similar across languages.

Advice for developers → Stop collecting languages; start collecting solved problems. Build a mental library of recurring features and failure modes.

The bigger picture → Engineers who master these patterns deliver reliable solutions faster, regardless of stack.

💡 Takeaway: The industry often glorifies breadth (“full-stack”), but long-term impact comes from depth in solving recurring, high-value problems.
