Full Stack Developer

I'm a Full Stack Developer with 2+ years of experience building responsive, scalable, and production-ready web applications. I've worked across the full stack — from AI-powered presentation editors and SEO platforms to SaaS products with complex subscription and payment systems. On the frontend, I build with React, Vue, Next.js, and TypeScript, using tools like Redux Toolkit, Pinia, TanStack Query, and Tailwind CSS. On the backend, I work with Node.js, Express, and MongoDB to design clean APIs and scalable server-side logic. I've integrated payment providers like Stripe and Shopify, built subscription management systems, and shipped features that directly impacted real users. I care about writing maintainable code, delivering great user experiences, and building things that actually work in production.
