Arjancodes

Yes — Arjancodes is a university lecturer in computer science as well as a YouTuber and entrepreneur. He brings over 20 years of professional software development and design experience to his teaching, which gives his channel a more academically rigorous tone than most coding tutorials on YouTube.

Python is the primary language across Arjancodes' content, covering everything from version-release breakdowns to idiomatic patterns like proper None-handling. He also frames lessons around broader software design principles — design patterns, OOP theory, clean code — that apply across languages, not just Python.

Arjancodes promotes a structured framework called "Learn how to design great software in 7 steps", which he features as a key resource linked from his Instagram bio. It reflects his emphasis on principled, systematic software design rather than just showing viewers how to write code that runs.

Yes — he published a video titled "A personal update: Life, AI, and ArjanCodes" addressing changes in his personal life and how AI factors into his work and channel's direction. It signals that he's actively grappling with how AI-assisted development is reshaping the software education landscape he operates in.

That's a recurring theme on his channel — one video is bluntly titled "You Think This Is Good OOP… It's Not," directly challenging assumptions developers commonly hold about object-oriented design. His broader content consistently pushes back on cargo-cult patterns and advocates for deliberate, principled design decisions over surface-level imitation.

Arjancodes covered this in a video titled "This Design Pattern Replaces an Entire Class Hierarchy," exploring how certain patterns can simplify deeply nested inheritance structures. This fits his broader mission of showing developers that cleaner, flatter designs are often more maintainable than the heavily class-based architectures many codebases accumulate over time.

Arjancodes has partnered with Hostinger, Squarespace, Incogni, Recall, and Akiflow — all delivered as YouTube integrations. The mix of web hosting, privacy tools, and productivity software maps well onto his developer and tech-professional audience.

Arjancodes explicitly targets intermediate to advanced developers — his stated goal is to help you "take your coding skills to the next level" rather than introduce programming from scratch. Topics like design pattern trade-offs, OOP critique, and Python internals assume viewers already know how to write and ship code.

Arjancodes covered the release in a video titled "Python 3.15 Is a Bigger Update Than I Expected," suggesting the version contained more meaningful changes than the Python community had anticipated going in. He regularly breaks down Python version releases as a way of keeping his developer audience current with the language they rely on.

Arjancodes is based in the Netherlands, though his audience skews heavily international. The largest share of his viewers comes from the United States, with significant audiences also in India, the United Kingdom, Germany, and Russia.
