About Me
Hi there! I'm a web application developer passionate about creating exceptional digital experiences. I specialize in building efficient and scalable web applications with a strong focus on user experience and modern best practices.
My core stack is centered on Shopify Plus (including the Admin API for custom storefront and ops integrations) and .NET Core with C# (ASP.NET MVC), alongside JavaScript / TypeScript, Node.js, React, and Next.js. I also have solid experience with SFCC from earlier e-commerce projects.
I build and maintain multi-regional e-commerce platforms with enterprise payment integrations—Chase Orbital, Cybersource, Adyen, PayPal, and Braintree.
Across the stack, I work as a full-stack developer with a strong focus on backend development and database architecture, manage CI/CD pipelines end to end, and deliver scalable, production-ready solutions for high-traffic retail environments.
