Danijel Dedic — Senior Full-Stack Engineer (React, React Native, TypeScript, Node.js)

Profile

Senior full-stack engineer (frontend, backend and mobile). I join product teams and ship: React and Next.js frontends, TypeScript / Node.js services and REST / GraphQL APIs, and React Native / Expo apps for iOS and Android. Most recently I have been building on an enterprise retail platform that directly processes roughly €10B in annual sales and is used by thousands of employees across 8+ countries — new Node.js services, frontend features, legacy modernisation and 2×–5× performance gains. Before that, six years of web, mobile and e-commerce delivery for international retail clients. Independent products from my playground are shown below.

What I can help with

React & Next.js applications — new features, API integration and the evolution of existing frontends.
TypeScript / Node.js backends — services, REST and GraphQL APIs, database and system integrations.
Modernisation — incremental migration off legacy stacks, refactoring, performance work and faster build & deploy pipelines.
Mobile — React Native / Expo apps for iOS and Android, from first build to the App Store.
E-commerce — storefronts, checkout flows and integrations on Magento, Shopware and Saleor.
