Over the years, I’ve worked on everything from simple landing pages to complex, custom-built platforms, which gives me the flexibility to handle a wide range of projects without guesswork. I work extensively with WordPress and Elementor, and I’m comfortable across platforms like Shopify, Webflow, Wix, and other CMS tools. My core stack includes HTML, CSS, PHP, JavaScript, and jQuery, so I can go beyond templates and deliver custom solutions when needed. On the design side, I use Photoshop and modern UI practices to create clean, practical designs that are built to perform. A big part of my work involves troubleshooting and repair. If a website is broken, slow, or behaving unpredictably, I can step in, identify the root cause, and fix it properly. I also handle website security, including malware and virus removal, cleaning hacked sites, and resolving issues with websites flagged by browsers or search engines. Speed and performance matter, so I regularly optimize websites that load slowly. This includes improving load times, reducing unnecessary scripts, optimizing assets, and making sure the site runs smoothly across devices. I also focus on onsite SEO, structuring websites so they are search-friendly from the ground up. This includes proper HTML structure, meta data setup, page speed improvements, schema implementation, and ensuring best practices that help improve visibility in search engines. I also handle website migrations between different platforms and hosting environments, including cPanel and Linux VPS servers, making sure everything transfers correctly with little to no downtime. On the marketing side, I build landing pages and automation systems using tools like GoHighLevel, Unbounce, Mailchimp, Klaviyo, and similar platforms. This helps turn traffic into leads and keeps systems running efficiently in the background. With a strong technical foundation and years of hands-on experience, I can take on both straightforward tasks and more complex challenges. Whether you need a site built, fixed, secured, optimized for search, or improved overall, I can step in and get it done. If you need someone who can handle the full scope of web work without constant back and forth, feel free to reach out. Let’s get your project moving. less -
