What to Avoid
❌ Trendy tech without ecosystem — Novelty doesn't pay the bills ❌ Over-engineering from day 1 — YAGNI (You Ain't Gonna Need It) ❌ Premature microservices — Monolith first, split later ❌ NoSQL databases without reason — SQL is still king for most cases
Conclusion
The best stack is one that lets you launch fast and scale when you need to. Don't complicate yourself with enterprise architectures when you're still validating your idea.
