Tolga EGE

Web Application Development

Single-page, real-time, progressive web applications — modern stack, fast UX, easy maintenance.

Web application development is the production of modern web software with rich user interaction, working without page refresh. Unlike classic corporate websites, it includes SPA (Single-Page Application), PWA (Progressive Web App) and real-time features.

As Tolga Ege we develop frontend with React, Next.js, Vue.js, TypeScript; backend with Node.js, Laravel, GraphQL. We implement real-time features with WebSocket, Server-Sent Events; offline support with Service Worker; local data storage with IndexedDB.
