As a Freelance Web Developer & Systems Support, I build and customize responsive pages in WordPress and HubSpot CMS, turning design comps and wireframes into functional web pages. I also audit sites with Screaming Frog and Lighthouse to identify performance bottlenecks, broken links, and unused code.

For my WordPress Performance Refactor project, I audited site assets, minified scripts, optimized image caching, and improved Core Web Vitals load times by over 30%. I’ve also implemented GA4 and Google Tag Manager tracking and connected lead capture forms to CRMs and marketing channels through Zapier and API integrations.
