About Me
My Journey
I am a Full-Stack Developer and IT Administrator with more than 8 years of professional experience. I develop web and mobile applications, while my infrastructure background helps me build solutions that are practical, reliable, and maintainable.
What I Focus On
I work best on projects that connect a clear interface with a concrete business goal. I care about responsive design, accessibility, implementation quality, and reliable integration between the frontend, APIs, and backend services.
How I work
I enjoy simplifying processes and turning user needs into concrete product capabilities. I combine independent delivery with teamwork, communicate risks clearly, and take ownership of getting work across the finish line.
Skills & Tools
I work with React, JavaScript, TypeScript, React Native, Gatsby, Node.js, Express, MongoDB, and MySQL. I also use Redux, TanStack Query, Git, Postman, and JIRA. My infrastructure experience includes Windows Server, Linux, Microsoft Active Directory, and Microsoft 365.
