I work with React, Next.js, Node.js, NestJS, Java Spring Boot, MongoDB, PostgreSQL, MySQL, and modern cloud technologies. I can manage the complete development process—from planning and UI implementation to backend development, API integration, testing, deployment, and ongoing maintenance.

My services include:
