I designed and developed the Photo Studio 308 website in WordPress for a New York City photography studio. The project focused on creating a clean, visual, mobile-friendly website that makes it easy for visitors to explore photography services, view portfolio work, learn about the studio, and request a quote. I handled the WordPress development, responsive page layouts, service and portfolio presentation, contact and quote functionality, Google Maps integration, blog structure, and overall frontend experience. The site was built to support both the studio’s photography business and its ongoing organic content strategy. This project demonstrates my ability to take a service-based business from its requirements to a complete, functional WordPress website with an emphasis on usability, maintainability, and conversion-focused design.

I designed and developed the GrowLense WordPress Connector, a custom integration that connects WordPress websites directly with the GrowLense Organic Growth AI platform. The connector securely links each website to its GrowLense business account using a unique connection key. It tracks important website activity including form submissions, phone clicks, email clicks, WhatsApp interactions, and WooCommerce purchases and revenue. I also developed the content synchronization workflow, allowing optimization recommendations and generated website content to be sent directly from GrowLense to WordPress. Content can be saved as a draft, published, scheduled, or used to update an existing page while preserving its URL slug. The project combines custom WordPress plugin development, PHP, REST API integration, analytics tracking, secure authentication, content automation, and database-driven SaaS functionality.

I designed and developed StudioCMS as a custom PHP/MySQL content management platform for building and managing business websites without relying on WordPress. The system includes theme management, dynamic forms, lead management, galleries, reservations, media management, user authentication, SEO controls, and configurable website settings—all managed through a centralized admin dashboard. Built with a focus on usability, scalability, and giving non-technical users an easier way to manage their websites and business workflows. Built with PHP, MySQL, JavaScript, HTML/CSS, and custom backend architecture.
