Organizations running mission-critical Python & Django platforms—from high-growth SaaS products to enterprise healthcare and FinTech monoliths—frequently search to hire a senior freelance Django architect programmer to upgrade legacy Django 2.x/3.x/4.x apps to Django 5.x, eliminate N+1 ORM queries, or integrate Django Ninja / DRF / Channels / Celery. I am Aldian Fazrihady, a Senior Freelance Python & Django Programmer with over a decade of deep Django expertise.
Core Django, DRF & Django Ninja Engineering Capabilities
- ORM Query Optimization (`select_related`, `prefetch_related`, `Prefetch`, `Subquery`, `Window`): Profiling endpoints with `django-debug-toolbar` / Silk / OpenTelemetry to reduce 400-query endpoints down to 2–3 indexed PostgreSQL queries.
- Zero-Downtime Django Migrations (`SeparateDatabaseAndState`): Adding non-null columns, renaming tables, and building concurrent indexes (`AddIndexConcurrently`) without locking production traffic.
- High-Speed Async APIs (Django Ninja & DRF) + WebSockets (Django Channels): Combining Django's battle-tested ORM, Admin, and auth ecosystem with Pydantic-powered Django Ninja endpoints and Redis-backed ASGI WebSockets.
Frequently Asked Questions
Can you upgrade our older Python 3.7/3.8 & Django 2.2/3.2 application to Python 3.12+ and Django 5.x safely?
Yes. I audit deprecated third-party packages, expand test coverage, resolve removed Django APIs step-by-step across LTS versions, and verify zero regressions in staging before production rollout.
How do I hire you as a freelance Django programmer?
Hire me via Upwork.
