Resource Requirements
Engineering Time
| Role | Hours Required | Notes |
|---|---|---|
| Backend Engineer | 40-50 hours | FastAPI, SQLAlchemy, Redis, KMS |
| DevOps Engineer | 15-20 hours | Kubernetes, CI/CD, monitoring |
| Python Developer | 15-20 hours | Client SDK development |
Total: 70-90 engineering hours
With 2 engineers working in parallel: 1.5-2 weeks
Budget
| Item | Cost | Type |
|---|---|---|
| GCP Infrastructure (running) | $310/month | Ongoing |
| Engineering (2 weeks) | $0 (in-house) | One-time |
| Stripe (testing) | $0 (test mode) | Free |
Total Additional Cost: $0 (infrastructure already budgeted)
Risk Assessment
High-Risk Gaps (Could Delay MVP)
| Gap | Risk Level | Mitigation | Impact if Delayed |
|---|---|---|---|
| FastAPI expertise | 🟡 Medium | Allocate senior engineer | +2-3 days |
| Identity Platform OAuth | 🟡 Medium | Start OAuth app review early | +1-2 days |
| Redis Lua scripting | 🟢 Low | Well-documented pattern | +1 day |
| GKE networking issues | 🟢 Low | Thorough testing | +1 day |
Low-Risk Gaps (Can Work Around)
| Gap | Workaround | Priority |
|---|---|---|
| Admin UI | Use API directly with curl/Postman | P2 (nice-to-have) |
| Stripe integration | Manually activate licenses | P2 (can automate later) |
| Advanced monitoring | Basic GKE logs sufficient initially | P2 (add Prometheus later) |

Comparison: Where We Are vs Where We Need to Be
Summary Table
| Category | Current % | Target % | Gap | Effort to Close |
|---|---|---|---|---|
| Infrastructure | 100% | 100% | 0% | 0 days |
| Security Services (KMS, Identity) | 0% | 100% | 100% | 2-3 days |
| Backend Application | 0% | 100% | 100% | 5-7 days |
| Deployment Pipeline | 0% | 100% | 100% | 2-3 days |
| Client Integration | 0% | 100% | 100% | 2 days |
| Overall System | 35% | 100% | 65% | 9-13 days |
Conclusion: We are 35% complete with the infrastructure foundation solid. The critical gap is backend application development, which requires 5-7 days of focused engineering effort. With proper prioritization and 2 engineers working in parallel, we can achieve a working registration and licensing system in 1-2 weeks.
Recommended Action: Start Phase 2 (KMS + Identity Platform) immediately this week to unblock backend development.
