Common Tech Stack Mistakes

Mistake 1: Over-Engineering

What you think you need:
├── Kubernetes cluster
├── Multiple microservices
├── Event-driven architecture
├── GraphQL federation
└── Real-time everything

What you actually need:
├── Single server
├── Monolith
├── REST API
└── Some real-time features

Mistake 2: Ignoring Team Expertise

Mistake 3: Premature Scaling

Mistake 4: Following Hype

Decision Process

Step 1: Define Constraints

Step 2: Evaluate Options

Score each option (1-5) on:

• Speed to market
• Scalability
• Hiring availability
• Cost
• Team expertise

Step 3: Make a Decision

Step 4: Document and Move On

Once decided:

1. 1 Document the reasoning
2. 2 Stop second-guessing
3. 3 Execute with full commitment
4. 4 Re-evaluate only if problems arise

Our Default Recommendations

For Most Startups

The "Just Works" Stack:
├── Mobile: Flutter + Riverpod + Dio
├── Backend: Supabase (PostgreSQL + Auth + Storage)
├── Additional APIs: Node.js/Deno Edge Functions
├── Hosting: Vercel/Railway
├── CDN: Cloudflare
└── Monitoring: Sentry + Mixpanel

For Enterprise-Ready

The "Scales Forever" Stack:
├── Mobile: Flutter or Native
├── Backend: Node.js/Go + PostgreSQL + Redis
├── Cloud: AWS or GCP
├── Auth: Auth0 or Cognito
├── Container: Docker + ECS/GKE
└── Monitoring: Datadog + PagerDuty

Conclusion

Technology decisions are business decisions. Choose your stack based on:

1. 1 Team expertise: What do you know?
2. 2 Speed to market: What gets you there fastest?
3. 3 Hiring realities: Can you find developers?
4. 4 Actual requirements: What do you really need?

Avoid:

• Hype-driven decisions
• Over-engineering
• Premature optimization
• Analysis paralysis

The best tech stack is the one that helps you ship and iterate fastest.
