Why a blog?​

Courses are great for structured learning. But many real-world questions are too specific for a course chapter:

• "How do I size a Kubernetes cluster on AWS for a SaaS with 1000 users?"
• "Should I use Glue or Athena for my CSV-to-Parquet pipeline?"
• "What's the cheapest way to run a small LLM in production?"
• "Which Spring Boot + AWS stack should I learn for a developer interview in 2026?"

These deserve focused articles, not full courses. That's what this blog is for.

What you'll find here​

1. Architecture deep dives — from real client problems, anonymized.
2. "Should I use X or Y?" comparisons (Lambda vs Fargate, Helm vs Kustomize, Bedrock vs OpenAI…).
3. Bite-sized tutorials with copy-paste code.
4. AI and tooling reviews (Claude Code, Cursor, Codex…).
5. Career posts for engineers navigating the global market.

How often?​

Aim: 1-2 articles per week. Quality over quantity.

Free, multilingual, no ads​

As with the courses, the blog is free, ad-free, and we never sell your data. Articles will progressively be available in our 8 languages.
