Today I focused entirely on backend robustness.
Instead of jumping to UI, I strengthened the analytics layer.
What I Added
1️⃣ API Usage Monitoring
Status codes
Request latency (ms)
Per-API-key tracking
Error rate calculation
2️⃣ Risk Intelligence Metrics
High / Medium / Low distribution
Risk percentage breakdown
7-day usage trends
Average risk score over time
3️⃣ Performance Metrics
Average latency
Error rate (%)
Per-plan breakdown
Real Bug I Faced
I hit this error:
sqlite3.OperationalError: no such column: analyzer_apiusage.latency_ms
The model was updated, but the database schema wasn’t.
Classic migration issue.
The fix:
Run makemigrations
Run migrate
Ensure correct module imports in models/init.py
Lesson:
Your ORM and your DB schema must always stay aligned.
Why This Matters
Before building UI, backend must be stable.
Now the system:
Tracks performance
Measures abuse
Prepares for production
Supports SaaS analytics dashboards
Next step: Backend hardening before frontend.
Security is not just detection — it’s architecture.
