Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
From the first alert through containment, eradication, forensics, and post-incident review — a structured playbook for handling web app breaches.
SSRF chains, deserialization, prototype pollution, CSPP, race conditions, and the subtle bugs that get past automated scanners. With Django-specific exploitation and defense.
A deep technical tour of the actual surface attackers probe in modern web apps — protocol quirks, header semantics, cookie behaviors, and the bugs they enable.
Who actually attacks web applications, what they're after, and the threat models that matter for SaaS, e-commerce, and B2B platforms in 2026.
Move beyond "int and str" type hints. Master TypeVar generics, structural typing with Protocol, TypedDict for JSON, mypy strict mode, and runtime validation with pydantic v2 — what production codebases actually use.
A pragmatic guide to caching in Django: choose the right level (site, view, fragment, low-level), avoid the stampede, and solve the only hard problem — invalidation — with versioned keys and signal-driven busts.
Move slow work off the request/response cycle. Architect Celery + Redis for production: workers, queues, retries with exponential backoff, periodic jobs with Beat, and live monitoring with Flower.
Advanced patterns for signals and middleware. Learn when signals cause more pain than value, how to write thread-safe middleware, audit logging, request tracing, and debugging production issues.
Practical, Django-specific defenses against the OWASP Top 10. Real attack examples and the exact code, settings, and tools you need to prevent them in production.
Build a complete CI/CD pipeline: automated tests, linting, security scans, Docker builds, and zero-downtime deploys. Reusable workflows, matrix builds, and deployment strategies.
Push your Django app beyond basic queries. Master B-tree vs GIN indexes, JSONB for semi-structured data, full-text search with ranking, and window functions for analytics.
Build lean, secure, production-ready Django Docker images. Multi-stage builds, dependency caching, non-root users, compiled static files, and health checks that shrink images from 1.2GB to 150MB.
Build a production-ready real-time Django app. Covers Channels architecture, WebSocket consumers, group messaging, authentication, Redis channel layer, and deployment with Daphne + nginx.
Master async programming in Python. Learn event loops, coroutines, tasks, aiohttp for concurrent HTTP requests, and when async actually makes sense vs. threads or multiprocessing.
Deep dive into Django ORM performance. Learn how to identify and fix N+1 queries, use select_related, prefetch_related, only(), defer(), and Django Debug Toolbar to measure the real impact.
Understand Django class-based views (CBVs). Covers ListView, DetailView, CreateView, UpdateView, mixins, and when to use CBVs vs FBVs.
