Darya Markova
@daryamarkova
I build high-performance frontend systems, real-time visualizations, and scalable application architectures.
Russian FederationWhat I'm looking for
I've built internet banking interfaces at PSB Digital, where I led architectural solutions, raised test coverage to 98%, reduced bundle size by 30%, and helped cut production bugs by approximately 20%.
Across PGK Digital and DataArt, I've delivered real-time railway tracking maps, route graph editors, predictive analytics tools, flight-booking experiences, multilingual learning platforms, and WebSocket chat interfaces. I enjoy turning complex data, algorithms, and business logic into fast, visual, usable products.
I'm comfortable taking projects from zero to production, designing component systems, reviewing code, and working across Angular, React, Vue, TypeScript, D3.js, Three.js, and map-based interfaces.
