Full Stack Developer with 2+ years of experience, including work at Deutics Global and Sprouto Group. I focus on React.js and Next.js, and at Deutics I cut unnecessary re-renders by about 40% in a production app (Camzify, an AI-powered surveillance platform). I also owned 20+ React components and integrated 15+ REST APIs with RTK Query and TanStack Query.

On the backend, I work with Node.js, Express and MongoDB: JWT authentication, protected routes, role-based access control and REST API design. Outside work, I've built an embeddable AI customer support chatbot (Next.js, Google Gemini, Scalekit) and a MERN e-commerce store with Stripe payments and an AI shopping assistant.

Core stack: MERN Stack, JavaScript, TypeScript, React.js, Next.js, Node.js, Express.js, MongoDB, Redux Toolkit, RTK Query, Tailwind CSS
