Deep technical craft & language internals

• antirez (Salvatore Sanfilippo) – Systems programming, Redis internals, and low-level engineering craft.
• Eli Bendersky – Compilers, Go, tooling, and low-level programming with clear technical writing.
• Dan Luu – Hardware, reliability, performance, and data-driven industry analysis.
• Fred Hebert (ferd.ca) – Erlang/Elixir, resilience engineering, and operating complex distributed systems.
• Sebastian Raschka – Advanced ML engineering and practical AI with strong technical depth.
• Simon Willison – Python, Django, SQLite, and practical backend engineering with deep dives.

Web & frontend at advanced level

• CSS-Tricks – Modern CSS, layout patterns, accessibility, and browser features (still strong for advanced frontend).
• Smashing Magazine – Front-end architecture, design systems, and accessibility best practices.
• Josh Comeau – Deep frontend craft, CSS, and interactive UI engineering.

Aggregators & newsletters

• InfoQ – Architecture, scalability, DevOps, and enterprise patterns.
• The New Stack – Cloud-native, Kubernetes, observability, and modern infra.
• ByteByteGo (Alex Xu) – System design diagrams, patterns, and real-world architecture breakdowns.

If you tell me your primary focus (backend/distributed systems, frontend architecture, data/ML, or language internals), I can narrow this to a short “top 10” list tailored to you.
