SaaS with Feature Flags Stack
I used to deploy new features to all users and hope nothing broke. Now everything ships behind a flag — dark-launch to 1%, roll out to 10%, graduate to everyone with a kill switch always ready.

Public stack
I had five years of Django code and wanted a modern React frontend without a full rewrite. This hybrid keeps the Python backend that works and replaces the Jinja templates with something my team actually enjoys.
Workflow stack
React frontend
Calls Django REST API endpoints from Server Components and client hooks — the frontend is fully decoupled but shares session tokens through httpOnly cookies.
Open tool profileDatabase
Django's ORM shines on Postgres — ArrayField, JSONField, and full-text search keep complex queries in Python without raw SQL sprawl across the codebase.
Open tool profileCache and tasks
Django caches hot database queries and uses Celery with Redis as the broker for background tasks like PDF generation and email dispatch.
Open tool profileHosting
Django web service and Celery worker as separate Render services sharing a Redis instance — auto-deploys from GitHub with no deployment YAML to maintain.
Open tool profileError monitoring
Django and Next.js SDKs both report to one Sentry project — Python backend errors and React client errors in the same issue tracker with shared team notifications.
