λ Lambda Classes

Think Deeply, Build Real

Whether you're mastering the foundations or contributing to real projects, Lambda Classes helps you grow through structure, reflection, and hands-on practice.

A Different Way to Learn Programming

Not Everyone Gets the Right Start

Many motivated and hardworking learners never get the chance to explore the foundations of programming. They're taught to code through tools, tutorials, and templates, but rarely through ideas.

Creativity vs Convention

Programming becomes a sequence of frameworks and patterns to memorize, rather than something to understand, shape, and enjoy. Creativity takes a back seat to correctness and convention.

🚀 A Better Way is Possible

Start with Thought, Not Syntax

It starts with learning the basic structures of thought, how to build, combine, and extend them. Not to follow rules blindly, but to use them as raw material for something more thoughtful.

What Lambda Classes Offers

Lambda Classes is an attempt to create space for that. A place to slow down, to question habits before they set in, and to see programming not just as a skill, but as a way of thinking.

About Your Instructor

Debjit Biswas

Hi, I'm Debjit Biswas, a programmer, mentor, and creator of Sim8085, a free web app used by thousands of students and educators to learn 8085 assembly.

I started programming in 2000 with BASIC. Over the years, I've worked with C, JavaScript, Haskell, Elm, Java, Go, Rust, and more. Professionally, I've been building software since 2009.

My work spans the full stack, from frontend architecture to backend systems and infrastructure. I've also contributed to open source tools like sudo and GNUSim8085, and led engineering teams.

What's always mattered most to me is writing software thats clear, elegant, and maintainable, not just code that works.

I created this course for those who want to understand programming deeply. Not just frameworks and syntax, but the ideas behind them, how to think, design, and grow real software.

If you've ever felt like you're missing the "why" behind what you code, this course is for you.
