💡 About Me
I'm a results-driven Full-Stack Developer with a strong focus on building modern, user-centric web applications.
I have hands-on experience developing Next.js and React projects using TanStack Query, Tailwind CSS, and shadcn/ui, delivering scalable and high-performance interfaces.
I've integrated Masterpass and other payment infrastructures to create secure and seamless checkout experiences.
My expertise also includes building real-time analytics dashboards, implementing custom GTM event tracking, and optimizing application performance through Lighthouse audits.
On the backend side, I have experience with .NET and C# MVC, allowing me to work across the full stack when needed.
I value clean, maintainable code, effective teamwork, and continuous learning to deliver impactful digital experiences.
