TheTechy

TheTechy is a focused, independent blog about software engineering — written for people who want to understand things deeply, not just use them.

The blog covers Python, systems design, the craft of writing good code, and the ideas that make software development more than just a job. Articles are written to last: they prioritize understanding over novelty, and first principles over recipes.

No sponsored posts. No ads. No fluff. Just articles and a free course, published at a sustainable pace.

The writing falls into a few broad categories:

• Tutorials — step-by-step guides for real problems, with working code and clear explanations.
• In-depth articles — longer pieces that go below the surface of a language feature, tool, or concept.
• Opinion — arguments about software development, engineering culture, and the craft.
• The Python Course — a free, structured course covering Python from the ground up, through 28 lessons across 6 modules.

The writing is aimed at working software developers — people who already write code and want to get better at it, or understand it more deeply.

I've worked on systems that serve millions of requests and on teams of two. I've seen what makes software easy to maintain and what makes it a nightmare. Most of what I write about comes from that experience.

Python has been my primary language for the past seven years, though the ideas here often apply much more broadly.

The best technical writing doesn't just teach you how to use something — it changes the way you think about a problem. That's the standard I hold this writing to.

If you can't explain it simply, you don't understand it well enough.

Every article here starts with a question I genuinely couldn't answer cleanly, or an explanation I couldn't find. Writing is how I answer them for myself, and hopefully for you too.

The Python course exists because learning a language well requires a curriculum — a deliberate sequence, not a collection of isolated tutorials. It's the course I wish existed when I started.
