No reviews yet

Hi, I am Sumit Kumar, a Full Stack (MERN) Developer and Trainer with over 3 years of experience.

I specialize in teaching JavaScript, React.js, Node.js, Express.js, and MongoDB with a practical, project-based approach. My focus is to help students not only learn theory but also build real-world applications like e-commerce websites, REST APIs, and full-stack projects.

I provide step-by-step guidance from beginner to advanced level, including hands-on coding, assignments, and doubt-solving sessions. I also help students with interview preparation, resume building, and becoming job-ready in the MERN stack.

My teaching style is simple, interactive, and focused on real understanding rather than memorization. I conduct classes via Zoom or Google Meet.

My teaching methodology includes concept clarity, hands-on coding, real-time projects, and regular assessments. I focus on building strong fundamentals along with practical implementation.

Students who learn with me gain confidence in building real-world applications, improve problem-solving skills, and become job-ready for full stack developer roles.

Feel free to connect with me for a demo class and start your journey towards becoming a confident full stack developer.
