Hi, I'm Usmonjon👋
I’m a middle-level JavaScript developer specializing in full-stack web development. I work with the MERN stack (MongoDB, Express.js, React.js, Node.js), as well as Next.js and NestJS. I have experience with both relational and non-relational databases, including PostgreSQL and MySQL. I’m also familiar with Docker, CI/CD pipelines using GitHub Actions, and DevOps fundamentals, focusing on building scalable, maintainable, and production-ready applications.

About Me
Curious about me? Here you have it:
I started learning web development in 2021, gradually building a strong foundation in JavaScript and modern web technologies. In January 2025, I began working professionally as a full-time developer, and since then I’ve been actively building and maintaining real-world applications in production.
Today, I work as a full-stack JavaScript developer, building scalable and maintainable web applications using technologies like Next.js, TypeScript, NestJS, PostgreSQL, MySQL, Docker, CI/CD with GitHub Actions, and more. My focus is on writing clean, structured code and delivering reliable solutions that can grow with the product.
I enjoy working on products end to end — from understanding requirements and planning architecture to development, deployment, and ongoing improvements. I’ve worked on a wide range of projects including CRM and ERP systems, SaaS platforms, e-commerce applications, Telegram bots and mini apps, as well as full-stack landing pages and multi-page corporate websites.
Outside of active development, I spend time learning new tools, improving my problem-solving skills, and following the journeys of startups and indie builders in the tech community. You can find my work and projects on GitHub or connect with me on LinkedIn.
Finally, some quick bits about me.
- Full-stack JavaScript developer
- Full-time professional experience

I’m always open to meaningful conversations about technology, products, and building better software — feel free to reach out and say hello 🙂
