At KONECRANES, I lead frontend development for an AI-powered internal platform, engineering a real-time interface with Next.js 15 and TypeScript. I use code splitting, lazy loading, and advanced caching to keep the UI responsive.

I establish frontend architecture guidelines, component patterns, and state-management strategies used by cross-functional teams. I also introduced end-to-end testing with Robot Framework and Playwright, improving UI stability by 50%.

Previously at MWDN, I built data-heavy cybersecurity dashboards and partnered with backend engineers to improve frontend performance by 40%. At ELEKS, I modernized a global stock-media eCommerce platform with React and Next.js, reducing web-vital load times by 30% and increasing code-quality scores by 70%.

Across React, Next.js, Vue.js, and Nuxt.js products, I build scalable interfaces, reusable component libraries, and seamless REST and WebSocket integrations.
