FAQ
Can you work with existing large-scale projects?
Yes. I have extensive experience in refactoring legacy code and migrating projects (e.g., from React Router v5 to v7). I focus on maintaining system stability while implementing modern functional components.
What libraries do you use for data visualization?
My primary expertise is with Highcharts. I can build complex, interactive dashboards and predictive maintenance visuals.
Do you provide responsive design using Material UI?
Absolutely. I use Material UI (MUI) to ensure that all dashboards and tools are fully responsive and look professional on desktops, tablets, and mobile devices.

It is highly recommended. For seamless integration, having clear API contracts or documentation helps me ensure the frontend and backend communicate efficiently without delays.
