What I'm looking for

I’m looking for remote freelance or contract work in custom WordPress development, Figma-to-WordPress delivery, existing-site improvements, or full-stack web development.

At Ultimate.Systems, I developed commercial React and Symfony applications, including CRM systems and real-estate portals. I also worked on WordPress website implementation as part of commercial web development projects.

In my independent software development work, I build and maintain WordPress projects, including a custom portfolio theme with modular PHP, SCSS, TypeScript, and ACF. The theme is responsive and production-deployed.

I also develop personal React and TypeScript applications and Node.js REST APIs. On Johnny Systems, I created a full-stack task management application with authentication and a relational database.

My work has also included React Native mobile applications and using MySQL, Docker, Git, and Jenkins. I’m available for remote freelance and contract work focused on custom WordPress development, Figma-to-WordPress delivery, existing-site improvements, and full-stack web development.
