Devops

GitOps mechanics, Argo CD vs Flux, app-of-apps, ApplicationSets, secret management, multi-cluster patterns, drift detection, and the production gotchas — explained without the cargo cult.

What platform engineering is in 2026, what makes a good Internal Developer Platform, the building blocks (Backstage, golden paths, paved roads, Crossplane), and a pragmatic path to introducing one without a 12-person platform team.

A pragmatic Linux server hardening checklist — SSH keys, non-root users, UFW firewall, fail2ban, unattended-upgrades, and the small habits that block most opportunistic attacks.

How to make a backend observable: structured logs, RED/USE metrics, distributed traces, and the tooling (Prometheus, Loki, OpenTelemetry, Grafana) that ties it together.

Build a real CI/CD pipeline for Python apps on GitHub Actions: lint, type-check, test with services, multi-version matrix, Docker build/push, and a deploy step that won’t break.

Everything an app developer should know about load balancers — L4 vs L7, distribution algorithms, health checks, sticky sessions, and which tools to reach for in 2026.

A no-fluff Kubernetes intro for app developers — what pods, deployments, services, and ingress really are, and how to ship your app onto a cluster without becoming a cluster operator.

A pragmatic Git workflow for solo developers and small teams: trunk-based commits, sane branching, rebases without fear, and the recovery commands you’ll thank past-you for memorizing.

Practical Docker for Python developers — write Dockerfiles that aren’t huge, use multi-stage builds, set up docker-compose for local dev, and learn the patterns production teams use.

An end-to-end guide to deploying Django to production: app server, reverse proxy, database, static files, env config, security hardening, and what to monitor.
