About Me

Full Stack Developer (Front-end Focus)

I'm a Full Stack Developer with a strong front-end focus, working in production environments across web and mobile. I specialize in React and Next.js with TypeScript, building maintainable component architectures, optimizing performance, and handling complex state at scale (Redux / Zustand). On the backend side, I build and maintain REST APIs and data flows, enforce runtime validation with Zod, and work hands-on with Prisma and relational databases (PostgreSQL / MariaDB) including schema design, migrations, and query optimization. I’ve shipped multiple live mobile app versions with major functional and architectural changes, implemented payments/subscriptions in production, and delivered features for large-scale systems serving hundreds of thousands of users.
