How I work on the frontend

I ship pixel-accurate UI from Figma or wireframes - spacing, typography and breakpoints are not approximate.

Legacy jQuery sites get incremental upgrades; greenfield projects use modern stacks (Astro for content sites, React/Vue for apps).

Bundle size and hydration cost matter: I avoid shipping a 400 KB framework when static HTML is enough.

For Warsaw and Polish clients I implement PL/EN versions, hreflang and fast static pages that rank in Google.pl.

US and EU products get analytics events, consent-aware scripts and CDN-friendly asset pipelines.

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

I am Viktar Liukevich, a frontend and full-stack developer in Warsaw with 15+ years of interface work - from jQuery shops to React dashboards and Astro content sites.

Clients hire me when they need a senior frontend developer who ships production UI: semantic markup, typed components, Core Web Vitals and analytics hooks - not Figma screenshots that break on real data.

When a project needs a dedicated React Native app, a Vue enterprise module or a motion-heavy Three.js scene, I bring in trusted frontend partners in Poland, Europe and the USA - each with a proven stack - under NDA. You still coordinate with me; I review every merge before release.
