Lineup · 08 speakers

Voices shaping the modern frontend

Eight engineers, designers, and toolmakers from across Europe sharing what they ship in production — performance wins, runtime trade-offs, framework internals, and the craft behind interfaces developers actually enjoy using. Tap any card to expand the talk details.

Keynote

Olena Marchenko

Principal Engineer · Vercel

Streaming SSR Without the Footguns

Bio

Olena leads framework infrastructure at Vercel and previously shipped the rendering pipeline at a major news platform. She speaks regularly about React internals, edge runtimes, and the human side of performance work.

Talk summary

A pragmatic tour through streaming server-side rendering — what actually breaks in production, how Suspense boundaries change your data layer, and the patterns that keep TTFB low without sacrificing developer sanity.

Mateusz Kowalski

Staff Engineer · Stripe

Type-Safe Forms at Scale

Bio

Mateusz works on Stripe's checkout surface, where every millisecond and every validation rule has revenue impact. He's a long-time TypeScript advocate and contributor to several form libraries.

Talk summary

From naive useState to schema-driven, end-to-end typed forms. Patterns for sharing validation between client and server, async field dependencies, and keeping bundle size honest as your form complexity grows.

Iryna Bondar

Sr. Frontend Engineer · GitLab

CSS Container Queries in Production

Bio

Iryna builds design system primitives at GitLab and writes about modern CSS for the wider community. She's obsessed with intrinsic layouts and the death of media-query-driven breakpoints.

Talk summary

A field report on migrating a 300-component design system to container queries: real refactor patterns, fallback strategies, and the surprising places `cqi` units changed how we think about responsive UI.

Tomáš Horák

Web Platform Lead · Mozilla

The View Transitions API, Demystified

Bio

Tomáš works on the Web Platform team at Mozilla, focusing on rendering and animation specs. He's contributed to MDN documentation and several W3C working drafts.

Talk summary

A practical, browser-agnostic look at View Transitions: how same-document and cross-document transitions actually work, where they replace heavy animation libraries, and what to do until full Firefox/Safari parity lands.

Anastasiia Levchenko

Tech Lead · Grammarly

Web Workers for Real Workloads

Bio

Anastasiia leads the editor platform team at Grammarly, where main-thread time is sacred. She's been pushing computation off the UI thread since before it was cool.

Talk summary

When and how to actually reach for Web Workers: messaging patterns, Comlink trade-offs, SharedArrayBuffer in 2026, and a live walkthrough of moving a heavy text-analysis pipeline off the main thread.

Dmytro Savchuk

Sr. Engineer · MacPaw

Bundlers Are Compilers Now

Bio

Dmytro maintains the build infrastructure for several MacPaw products and is a frequent contributor to Vite and Rolldown. He enjoys reading source code more than most people enjoy coffee.

Talk summary

Modern bundlers do tree-shaking, code-splitting, transforms, and module federation — that's a compiler. We'll trace a single import through Rolldown, demystify the IR, and show how to write plugins that don't fight the toolchain.

Sofia Reinhardt

Accessibility Engineer · Shopify

A11y Beyond the Lighthouse Score

Bio

Sofia is an accessibility engineer at Shopify and a screen-reader user herself. She advocates for accessibility as a craft, not a checklist, and has helped ship a11y tooling used by thousands of merchants.

Talk summary

Why a 100 Lighthouse score still ships broken experiences. Real-world failure modes, ARIA patterns that quietly mislead, and how to build automated tests that catch what auditors actually catch.

Ravi Shankar

DX Engineer · Sentry

Debugging the Frontend in 2026

Bio

Ravi works on Sentry's frontend monitoring SDKs and spends his days reading stack traces from broken websites. He has strong, well-earned opinions about source maps.

Talk summary

A modern toolbox for diagnosing production issues: session replay, profiling APIs, source-map hygiene, and the underrated DevTools features that turn 4-hour debugging sessions into 4-minute ones.

More speakers and lightning talks announced weekly. Grab your spot before the lineup fills up.
