About solidcoder

solidcoder is a set of practical, interview-focused courses for software engineers — built and taught the way senior engineers actually think, not the way a textbook explains it.

The flagship course, Machine Coding Mastery, is a hands-on low-level design course covering OOP fundamentals, SOLID principles, UML, design patterns, concurrency and multithreading, and how to use AI-assisted coding without shipping fragile code — everything needed to go from a blank editor to a clean, interview-ready system. DSA Foundations, High-Level Design, and AI Engineering are in development.

solidcoder started as a YouTube channel teaching the machine coding interview round, and has grown into full courses from that same practical, no-fluff approach.
