About Me

My Journey

I build full-stack web apps, mobile apps, backend systems, and AI-assisted tools that save time and scale reliably. Specializing in React, Next.js, React Native, Python, Node.js, and Docker across frontend, backend, mobile, and automation.

I specialize in full-stack development with expertise across multiple domains. On the front-end, I work with React, Next.js, and TypeScript to build modern web applications. As an expert mobile developer, I create cross-platform mobile apps using React Native. For backend development, I design and implement robust APIs, microservices, and database solutions using Node.js, Python, and various database technologies. I believe in writing clean, maintainable code and creating intuitive user experiences across all platforms.
