500 USD Gifton Space - online store of handmade candles
Website Development
I created a custom e-commerce website for Gifton Space — a store selling handmade designer candles. The client's goal was to have a warm, cozy online presence that reflects the authentic nature of their brand while making the process of selecting and purchasing candles simple and convenient.
The website was developed on Wix with a clean and modern design that highlights the beauty of each product. I implemented a user-friendly store system, product filtering, and an intuitive checkout process. Additional design elements were created specifically to give the store uniqueness instead of using standard templates.
… I optimized the site for speed and mobile responsiveness, ensuring a comfortable viewing experience on any device. SEO optimization was also performed for better visibility in search and basic marketing tools were integrated for further development. As a result, it turned out to be a cozy, modern, and sales-oriented online store that conveys the brand's story and makes the shopping process as easy as possible.

900 USD Cosmo Code Cosmetics - online cosmetics store in Dubai
Website Development
I developed a fully customized e-commerce website for Cosmo Code Cosmetics — a cosmetics distributor based in Dubai, UAE. The goal was to create a unique, high-performance online store that reflects the premium image of the brand and provides a seamless shopping experience for customers in the UAE.
The site was built on WordPress using WooCommerce and Elementor. It features a unique design (no templates) and enhanced functionality through custom solutions in HTML, CSS, JavaScript, and PHP hooks. I integrated Stripe for secure payments through various methods, including credit cards, Apple Pay, Google Pay, and others. Additional features include automatic calculation of 5% VAT for the UAE and a customized delivery system that allows orders to be placed only within the UAE while keeping the catalog available for viewing worldwide.
… The website is fully responsive, hosted on GoDaddy, optimized for maximum speed through advanced caching, image compression, and performance tuning. I performed complete SEO optimization, including keyword research, on-page SEO, meta tags, structured data, and performance-based ranking improvements for better visibility in search engines.
As a result, a fast, secure, and conversion-oriented online store was created, helping the brand stand out in the competitive cosmetics market.

600 USD Flowers Lace Studio - online flower shop
Website Development
Flowers Lace Studio is a boutique floral business that offers bouquets, wedding arrangements, handmade candles, balloons, and personalized event decoration services. The client aimed to create a modern and user-friendly e-commerce website that reflects the elegance and charm of the brand while providing a seamless shopping experience.
The main goal was to develop a minimalist yet visually appealing site where users could easily browse products, order event services (such as Flower Bar), and place orders with flexible delivery options. Key features included: product categories, event decoration request form, delivery check by postal code, and the ability to choose a convenient delivery time slot.
… The challenge was to implement a delivery system considering location, flexible pricing, and time slot selection within the platform's constraints. To address this task, I applied smart form integrations and custom logic that allowed users to check delivery availability and select a convenient time based on their postal code.
As a result, a clean, intuitive, and fully responsive website was created on Wix, designed to support the growth of Flowers Lace Studio and ensure a pleasant user experience. The final product successfully combined functionality and beauty — just like the brand itself.
