Arun Kumar

I started my career as a front-end developer. Then I began teaching, and somewhere along the way, I fell in love with it. I don't teach syntax first. I start with a project, build each concept around it, and make sure students leave with the mental model, not just code they can copy. The moment a student says, "Whoa, I finally get it," is the reason I teach. I also love building frontend websites that put smiles on people's faces and leave them thinking, "How did they do that?"

Frontend Developer at TransPerfect (2022-11 – 2024-01)

• Developed responsive user interfaces using React.js, CSS, and Tailwind CSS.
• Built reusable React.js components for new features and easier code maintenance.
• Connected frontend components with REST APIs to display dynamic data.
• Fixed UI bugs and improved the application's responsiveness across different devices.
• Worked with developers to build new features and maintain existing web applications.

MERN Trainer at KG Micro-College (2024-02 – 2026-03)

• Taught MERN stack by building projects instead of teaching concepts in isolation.
• Built the training material from scratch, including coding exercises, mini-projects, and a capstone project.
• Broke down topics that beginners usually struggle with into simple, visual explanations.
• Helped students understand not just what to write, but why the code works.
• Focused on helping students build mental models.

Founder at The Stargate Solutions (2026-04 – Present)

• Designed an industry-relevant curriculum covering HTML, CSS, JavaScript, and React using a gamified, project-based pedagogy that builds strong mental models.
• Designed a backend curriculum covering Express.js, MongoDB, REST APIs, CRUD operations, and JWT authentication using the same project-based pedagogy.
• Developed a project-based teaching methodology where students start by building projects instead of learning concepts one after another. Concepts are introduced only when they are required, allowing students to learn, practice, and immediately apply each concept, reducing cognitive overload and helping them build strong mental models.
• Built a prototype LMS featuring video lessons, notes, images, interactive components, live coding playgrounds, and a story-driven game where the story progresses only when students write the expected JavaScript code. LMS Demo:
• Created course material on AI-assisted frontend development using Next.js, modern AI coding workflows, Claude Code, and scroll-based animations. Sample Projects: and
