Freelance Full Stack Developer | MERN, Next.js & E-commerce | CTO at Zynetechs
Hi, I'm Rahul Jangir, a freelance full stack web developer based in Jaipur, Rajasthan. Before any title, I'm a developer and freelancer at heart — I take client projects directly, so you work one-to-one with the person building your product.
I'm also the Chief Technology Officer (CTO) at Zynetechs, where I lead technology and product architecture — engineering high-speed Next.js web applications, e-commerce platforms and scalable systems for businesses across India and globally. That experience goes into every freelance project I deliver.
With deep expertise in the MERN Stack (MongoDB, Express.js, React.js, Node.js), Next.js, Laravel, and 3D web technologies (Three.js / WebGL), I architect solutions that combine robust backends with immersive visual experiences.
I focus on system design, performance optimization, and building resilient software architectures that scale effortlessly. Whether collaborating with businesses on digital transformation or engineering custom products, I bring technology and strategy together.
