About this gig
Need a custom feature that your Squarespace editor can't handle?
I help turn specific ideas, design limitations, and functionality gaps into working solutions using custom code, CSS, HTML, and JavaScript.
I can help with:
Custom code injection
CSS styling and layout adjustments
Custom HTML elements
JavaScript interactions
Forms and custom functionality
Responsive behavior fixes
Third-party integrations
Existing code troubleshooting
Custom features for your current site
Whether you need a small code adjustment or a more advanced customization, I first understand what you need and then build the solution around your existing setup.
I focus on clean implementation, responsive behavior, and functionality that works properly across devices.
Have a feature in mind that isn't available natively? Send me the details and let's discuss the best way to implement it.
