At Raiffeisen Bank, I led the migration from a monolithic frontend to a Single-SPA microfrontend architecture, enabling independent team ownership and reducing feature delivery time by 23%.
I led frontend development of a new payment module serving millions of users worldwide. I designed a configuration-driven architecture to support diverse payment flows and simplify future business changes.
At Leeto Digital Agency, I built complex frontend modules for a global real estate CRM used across 20+ countries. I also led development of Walletii, establishing an Nx monorepo with Atomic Design and country-specific applications and dependencies.
I improved performance in large React applications through SSR, code splitting, lazy loading, memoization, and targeted legacy-code refactoring. I’ve also built shared UI libraries used across 10+ microfrontends and defined frontend engineering standards across three product teams.
