ABOUT THE ACADEMY
Learn by building,
not by guessing.
Proof Of Concept Code Academy is where developers turn confusing concepts into things they can actually build. Learn through practical, Hinglish lessons on Java, Spring, APIs, system design, and the developer skills that make a real difference at work.
MEET YOUR INSTRUCTOR
Hi, I'm Chandan Tiwari.
I'm a Software Engineer, lifelong learner, and the person behind Proof Of Concept Code.
I have a small confession: I do not love coding for the sake of coding. What I genuinely enjoy is taking a difficult technical idea, breaking it apart, and helping someone reach that satisfying “oh, now I get it” moment.
That is why I teach. Through YouTube and this academy, I share the concepts, patterns, and practical thinking that have helped me as an engineer: from REST APIs and multithreading to resilience, system design, and the skills behind confident technical interviews.
The goal is not to memorise more theory. It is to build context, practise with purpose, stay curious, and leave each lesson able to use what you learned.
