The Story Behind Rajath Kumar

My journey from writing first lines of code to building IoT and AI systems for enterprises

My Journey

With a decade of experience in software and embedded systems development, I have successfully built production-grade IoT devices, firmware solutions, and full-stack applications. My journey started with bare-metal programming on 8-bit microcontrollers and evolved into building complex ESP32-based IoT systems with ESP-IDF.

I specialize in embedded firmware development using ESP-IDF, FreeRTOS, and low-level C programming. I've built production IoT devices featuring WiFi/BLE connectivity, MQTT/HTTP protocols, OTA updates, and secure boot implementations. My expertise spans from PCB bring-up to cloud integration.

Beyond embedded systems, I build enterprise-grade web applications with Python (Django, FastAPI) and pioneer AI solutions using LangChain, RAG systems, and LLM integrations. I bridge the gap between hardware and software, creating end-to-end IoT solutions.

A passionate educator with 50,000+ students mentored across bootcamps, workshops, and corporate training programs. I specialize in hands-on, project-based learning that transforms beginners into production-ready embedded developers.

Teaching Philosophy

Why I Teach

Learn by Doing

I believe the best way to learn AI is by building real projects. Theory is important, but hands-on experience is what truly makes concepts stick.

Practical Over Perfect

I focus on teaching what actually works in production. No academic fluff—just battle-tested techniques and best practices from real deployments.

Community First

Learning is better together. I foster a supportive community where students help each other grow and share their AI journey.

My goal isn't just to teach you ESP32—it's to help you build production-ready IoT firmware. Every student who walks away from my workshop should feel confident building real-world embedded systems.
