Upwork achievements: 100% Job Success 🌟 Top Rated Plus 🚀 Web developer with over a decade of expertise in creating web applications and APIs. Proven track record of delivering high-quality solutions in both small startup and large enterprise environments. Technologies I use in frontend: Angular, Ionic, Nx, NgRx, RxJS, Three.js, D3, Playwright, Jest, TypeScript, Angular Material, Bootstrap, SAP Spartacus... I can architect and implement web apps of varying complexities, ensuring high performance and maintainability. Can upgrade your app to the latest version of Angular, incorporating new features and optimizations. I can create a "zoneless" Angular app, for the best performance possible, close to vanilla JS. I know all the latest features of Angular (Signals, Standalone Components, lazy loading...) and can consult your team. Extensive experience in building robust systems including WMS, CRM, and ERP applications, with a focus on scalability and user experience. Proficient in creating data visualizations using Canvas API, WASM, Three.js, Service Worker API, and many others, ranging from simple charts and animated UI parts to advanced 3D modeling applications.
