281 USD Online store WordPress + WooCommerce (custom theme)
Web Programming
Development of an online store on WordPress + WooCommerce (custom theme, individual design, multilingual, SEO)
Project: a full-fledged online store from scratch for selling approximately 30 products, with a custom design, responsive layout, integration with Nova Poshta, multilingual support (UA/EN), and SEO optimization.
… What has been implemented:
• Developed a unique WordPress theme from scratch, without using ready-made templates. To ensure high site speed, flexibility, and clean code.
• The site consists of two main (third by default) pages with anchor navigation (home + services (+ checkout)).
• The layout is responsive — the site looks equally good on a computer, tablet, and mobile phone. Retina display support has been implemented.
• All code complies with W3C standards. Utilized PHP, HTML, CSS, JavaScript.
• Integrated delivery via Nova Poshta API. Users can choose: branch, parcel locker, or courier delivery.
• Added dynamic text and photo change for products when selecting options (without page reload).
• Implemented multilingual support: the site is available in Ukrainian and English.
• For SEO, a custom plugin was developed that allows setting Title, Meta Description, and Meta Keywords separately for each language and page.
• After placing an order, data is automatically sent to Google Sheets. Contact form submissions are also sent to Google Sheets.
• Added video playback on the site via JS player.
• Implemented light animations of products and site elements to improve visual perception.
Result: a fast, lightweight, responsive, and user-friendly site with all necessary features for effective online sales.

Mobile application for creating images using AI
App Development for Android
To implement this project, I used the Flutter framework combined with various backend technologies, including Firebase, MySQL, PHP, and Dart Server. Firebase was used to provide user authentication and real-time data synchronization. MySQL and PHP were used to build a powerful server-side layer that handled various requests and stored data in a structured format. Dart Server was responsible for processing server-side requests, ensuring fast and efficient application performance.
Additionally, Python machines were used for content generation, highlighting the scalability and complexity of the development approach. This approach allows for high quality and efficiency of the product, considering the latest technological solutions.
