Cover image for Senior Full-Stack Development — React, Node.js & Spring Boot
I build fast, scalable full-stack applications using React, Node.js, Spring Boot, PostgreSQL, and MongoDB. I can take a project from initial planning to production—designing the architecture, building reliable APIs and database layers, developing responsive user interfaces, integrating third-party services, and supporting deployment.
My focus is long-term quality: clean architecture, maintainable code, clear separation of concerns, reusable components, secure APIs, efficient database design, and documentation that makes future development easier for any team. I communicate clearly, provide regular progress updates, and deliver work in small, reviewable iterations so you always know what has been completed and what comes next.
Whether you're launching an MVP, adding features to an existing application, modernizing a legacy system, or improving backend performance, I deliver production-ready software designed to be stable, maintainable, and ready to scale.
