Docker & Kubernetes in Production: From Dockerfile to Zero-Downtime Deployments

Getting Docker working locally is easy. Getting Kubernetes running reliably in production is an entirely different discipline. This guide bridges the gap — from writing production-grade Dockerfiles to configuring Kubernetes rolling updates, resource limits, health probes, horizontal pod autoscaling, and secrets management. Learn what actually breaks in production and how to prevent it.

Git Advanced Workflows: Rebase, Cherry-Pick, Bisect, Hooks & Team Branching Strategies

Most developers use Git as a save button. Advanced Git users wield it as a precision instrument — rewriting history to tell a clear story, surgically applying specific commits across branches, bisecting thousands of commits to find the one that introduced a bug, and automating quality gates with hooks. This guide covers everything from interactive rebase to git bisect, team branching strategies, and conventional commits.

CI/CD with GitHub Actions: Build Pipelines, Automated Testing, Docker & Deployment to Vercel & AWS

Manual deployments are a relic of the past. A mature CI/CD pipeline catches bugs before they reach production, enforces code quality standards, builds and pushes Docker images, runs security scans, and deploys to multiple environments automatically. This guide builds a complete, production-grade GitHub Actions pipeline from scratch, covering parallel job execution, caching dependencies, environment-specific deployments, and rollback strategies.

How Cloudflare Handles 20% of Global Internet Traffic: Anycast, XDP & eBPF Under the Hood

Every day, one in every five HTTP requests on Earth passes through Cloudflare's network. But how does a single infrastructure withstand 70+ million HTTP requests per second, mitigate multi-terabit DDoS attacks in real time, and route traffic across 330+ cities with sub-millisecond edge latency? In this architectural deep dive, we explore BGP Anycast routing, kernel-bypass packet filtering with XDP/eBPF, Unimog Layer-4 load balancing, and Pingora — Cloudflare's Rust-powered proxy that replaced NGINX.
