Data structures & algorithms
Core CSPattern-based problem solving — arrays, trees, graphs, and dynamic programming, taught for interviews.
You'll build: a personal problem-solving playbook you can reuse in any interview.

MERN, JavaScript, DSA, AI engineering, project building, and system design —
one path, real projects, no fluff.
Six tracks in progress. New write-ups publish here first.
From variables to closures, promises, and modern ES6+ patterns — the language behind everything else here.
You'll build: small interactive projects that lock in each concept as you go.
Pattern-based problem solving — arrays, trees, graphs, and dynamic programming, taught for interviews.
You'll build: a personal problem-solving playbook you can reuse in any interview.
MongoDB, Express, React and Node — how a full-stack web app actually fits together in production.
You'll build: a full-stack app with auth, a database, and a deployed frontend.
RAG pipelines, LLM app patterns, and voice AI — how we build the AI features inside DigitalAIIndia itself.
You'll build: a real RAG pipeline and a voice AI integration, end to end.
High-level and low-level design — how to structure a growing product so it doesn't fall over.
You'll build: HLD/LLD diagrams for a system that's designed to scale.
Turn what you've learned into something real — planned, built, deployed, and documented like a shipped product.
You'll build: a portfolio-ready project, deployed and documented.
Every track fits into the same journey — skip ahead if you already know a stage.
Most tutorials teach syntax. We show how real products get built and shipped.
A preview of the AI engineering track — pulled straight from our own codebase. More tracks are being written.
