Capabilities

All skills

Modern Frontend Development

Responsive interfaces with Next.js, React, TypeScript and Tailwind CSS — clean layouts, smooth interactions and reusable components. This portfolio and my Silent Help project are where I push advanced UI and real product thinking.

AI-Assisted Workflows

I use AI throughout my development process to move faster and think wider — exploring solutions, refactoring, generating tests and improving docs. In Silent Help, AI powers features that actually support users, not gimmicks.

Web Platforms & Integrations

Comfortable beyond pure frontend when a project needs it: WordPress customisation for client work, plus MySQL, JSP/Java and Laravel basics for connecting UIs to databases and APIs.
