Romania

Message

At Bytex Technologies, I implemented scalable, reusable UI components with React and Ant Design, along with form components and validations using Formik.

I also implemented map and graph UI components using Google Maps API and D3, and wrote unit tests with Jest and React Testing Library. I organized presentations to share knowledge within the company.

Earlier, at SpryBase - Web applications and e-commerce, I implemented React UI components for an internal CRM project, built presentation websites with WordPress, and translated Photoshop designs into HTML and CSS layouts. I’m continuously curious about frontend technologies.
