About this gig

Looking for a developer who can take your project seriously not just write code, but think through the architecture, handle edge cases, and deliver something that actually works in production?


I specialize in React and Next.js development, with experience across SaaS platforms,  business systems, and data-heavy applications. I've worked with international corporate  clients and know what production-grade code looks like.


What I can build for you:

· Web apps with authentication, user roles, and dashboards

· API integrations (REST, GraphQL) with React Query or Redux

· Data visualization: charts, tables, and interactive graphs

· Interactive maps with Mapbox GL

· Admin panels and business management systems

· Full Next.js apps with SSR/SSG, Route Handlers, and Middlewares


My stack:

React · Next.js · TypeScript · TailwindCSS · React Query · Mapbox GL · ApexCharts · AG Grid · Material UI · Ant Design · ShadCN · AWS Lambda · Supabase


Every delivery includes clean, documented code, responsive design, and 

cross-browser compatibility. I communicate clearly throughout the project 

and don't disappear after delivery.


Let's talk about your project before you order.
