What I'm looking for

I'm looking to build high-performance, scalable web products where I can lead frontend architecture, create maintainable component systems, improve UX, and mentor engineers.

I've led frontend architecture and core feature development for Piletilevi Group's high-traffic Pan-Baltic ticketing platform, focusing on stability, low-latency rendering, and scalable delivery.

I built a modular React and TypeScript widget and core UI library from scratch, enabling GraphQL and REST integrations across external CMS setups including Directus. I also optimized assets and bundle sizes, monitored production behavior with Sentry, and strengthened code review and release workflows.

Across Web Expert, Brainbase, Uptime, and Tele2, I've delivered enterprise web solutions, reusable component libraries, single-page applications, e-commerce flows, and responsive interfaces using React, Next.js, Vue, Nuxt, Angular, and REST APIs.

I've been building web experiences since 2004, from digital design and interactive campaigns to data-driven frontend systems. I enjoy clean component libraries, pixel-perfect UX/UI execution, technical mentoring, and maintainable frontend architecture.
