The company data uses 'name' property, but the code references 'companyName' which doesn't exist in the JSON structure. This will result in empty alt text and no company name being displayed. Change 'company.companyName' to 'company.name'.

Using useState for static JSON data is unnecessary. The data from JSON imports is already immutable and doesn't need to be stored in state. Remove useState and use the imported data directly: pass companiesData and technologiesData as props instead of companies and technologies.

Wrapping a button inside a Link creates nested interactive elements, which can cause accessibility and usability issues. Remove the button wrapper and style the Link directly, or use navigate from useNavigate hook instead.

Extensive inline styles make the code harder to maintain and reuse. Consider moving these styles to CSS classes in a stylesheet, especially for repeated patterns like the card components.

The website URL is directly interpolated without validation. If the website field contains a malicious protocol (e.g., 'javascript:alert(1)'), this could lead to XSS. Consider validating that the website starts with 'www.' or using URL validation before constructing the href.
