Technical Architecture Reviews & Design Decisions
Lead rigorous architectural reviews within startup constraints
What You Can Do
You get a structured framework for evaluating architectural options, design decisions, and technology choices while accounting for startup realities—limited budget, small teams, and aggressive timelines. Claude conducts thorough reviews of monolith vs. microservices, database migrations, tech stack changes, and infrastructure decisions, providing trade-off analyses, risk assessments, and phased implementation roadmaps.
Features
Structured format for evaluating 2-3 architectural options against weighted criteria relevant to your constraints.
Automatically factors budget, team size, timeline, and growth projections into recommendations.
Compares options across dimensions like implementation time, operational complexity, scalability, and cost.
Identifies technical, organizational, and business risks for each option with priority and mitigation strategies.
Shows how architectural decisions impact adjacent systems and existing infrastructure.
Breaks large architectural changes into achievable milestones with resource estimates and success criteria.
Estimates engineer-hours per phase and identifies skill gaps or hiring needs.
Comprehensive criteria for evaluating database migrations, API design changes, and infrastructure decisions.
Example Output
Decision Matrix Example:
| Option | Time to MVP | Monthly Cost | Scalability | Maintenance | Team Ramp | Recommendation |
|---|---|---|---|---|---|---|
| Monolithic REST | 4 weeks | $3k | Moderate | Low | Immediate | ✓ Best for MVP |
| Microservices | 8 weeks | $5k | High | High | 3 weeks | Good at scale |
| Serverless | 5 weeks | $8k | High | Low | 2 weeks | Most costly |
Risk Assessment Example:
- Technical Risk (High): Database migration downtime; Mitigation: Use dual-write pattern
- Team Risk (Medium): PostgreSQL learning curve; Mitigation: Pair junior devs with experienced engineer
- Business Risk (Low): Timeline delay; Mitigation: 6-week plan includes 1-week buffer
Phased Roadmap Example:
- Phase 1 (Weeks 1-2): Schema design, test environment migration
- Phase 2 (Weeks 3-4): Dual-write layer, production cutover prep
- Phase 3 (Weeks 5-6): Live migration window (2am UTC), rollback testing
