Demystifying Async Django: When to Use `async def` vs. Background Workers
Async Django views promise high concurrency, but misunderstanding thread handoffs and blocking ORM calls can ruin performance. Learn exactly when to employ ASGI async def versus offloading to asynchronous worker pools.
Webhook Security: HMAC SHA-256 Signature Verification & Replay Attack Defense
Public webhook endpoints are prime targets for spoofed events, timing attacks, and replay vulnerabilities. Learn how to verify HMAC SHA-256 signatures in constant time, enforce timestamp tolerance windows, and decouple processing.
PostgreSQL at Scale: Partial Indexes, Partitioning & JSONB Optimization
When PostgreSQL tables grow beyond tens of millions of rows, default B-tree indexing and sequential scans cause query degradation. Learn how to leverage partial indexes, range partitioning, and GIN JSONB optimization.
Hypermedia Over SPAs: Building Reactive Web Apps with Django & HTMX
Single Page Application (SPA) architectures introduce bloated JavaScript bundles, state synchronization traps, and fragile build pipelines. Here is how to build responsive, reactive web applications using Django and HTMX.
