Top SchoolArtem Holinka is a Senior Frontend Developer based in Warsaw with 9 years of experience building high-traffic web and mobile products across marketplaces and fintech.

Artem specializes in performance-focused frontend work, driving measurable improvements like reduced scripting time, impression logging gains, and smoother scrolling on low-end devices through virtual scrolling and skeleton loaders. He’s experienced in refactoring legacy codebases for TypeScript adoption, migrating SPAs to SSR, and establishing mobile development best practices. Comfortable both as a hands-on engineer and a technical lead, he combines product-minded feature delivery with deep performance research and testing. Outside of the obvious metrics, he’s pragmatic about tooling and architecture decisions that improve retention and conversion rather than just developer convenience.
