I am a Shopify and Full Stack Developer with 6 years of hands-on experience building e-commerce stores, web, desktop, and mobile applications. My core specialty is Shopify development. I have built and maintained 8 live Shopify stores serving customers in 6 languages across Europe and the US, along with custom Shopify apps. My Shopify work covers complete store builds, theme customization, custom app development, API integrations, GA4 and pixel tracking, speed optimization, and multi-language, multi-currency setups for international selling. Alongside Shopify, I work as a Full Stack Developer, developing and maintaining a rewards platform using React.js and Next.js, integrating third-party networks, and building scalable frontend and backend features. Previously, I worked as a Business Application Programmer, maintaining enterprise desktop and web applications using .NET technologies and WPF, and as an iOS Developer, building mobile applications using SwiftUI and UIKit. I also completed a Data Science internship at Systems Limited, gaining experience with cloud platforms, CI/CD pipelines, and modern development practices. My expertise includes Shopify Development (Liquid, Shopify APIs, custom apps), Full Stack Development, React.js, Next.js, .NET, API Integration, Database Management, Mobile App Development, Cloud Technologies (AWS & Azure), and performance optimization. I deliver clean, maintainable solutions — and I stay available after delivery, not just until it
