I build scalable Vue and Nuxt applications for CRM, POS, and e-commerce.
UkraineWhat I'm looking for
I've built CRM, POS, e-commerce, and analytics applications over five years of commercial frontend development.
At if.team, I architected a reusable Vue 3, Nuxt.js, TypeScript, and Pinia component library for enterprise CRM modules. I improved SSR and rendering performance by about 35%, while adding real-time REST API and WebSocket updates.
At CHM software Ltd, I built a visual store-layout constructor that reduced POS configuration time by about 60%, alongside inventory and goods-receiving workflows that saved more than 10 hours of manual work each week.
At Sellpoint and Vantino, I delivered e-commerce flows, responsive Nuxt.js interfaces, reusable components, and pixel-accurate layouts. I focus on clean architecture, maintainable business modules, and faster user experiences.
