Career Journey
Frontend Engineer
Innovatrics (Biometric) • Oct 2024 — Present
- Optimized a performance-critical identity verification flow (capture → validation → result) by reducing redundant GraphQL requests by ~33%, improving TanStack Query caching, and eliminating unnecessary re-renders, accelerating data load time from 4.1s to 3.2s (~21%).
- Refactored a legacy biometric UI used across 4 production applications into a modular React component architecture within a shared monorepo, eliminating cross-module duplication and improving maintainability.
- Contributed to the development of a biometric identity verification platform that processed 83M+ successful verification requests within the first two months of production.
- Collaborated with QA to redesign the Playwright E2E test architecture across three production applications in a shared monorepo, introducing shared fixtures and reusable helpers that reduced CI test runtime from 1h17m to 53m (~31%) and improved test reliability and maintainability.
- Designed a shared frontend verification package used across multiple applications, standardizing domain logic and reducing duplicated implementation across teams.
Frontend / Full-Stack Developer
Softec (Banking) • Jan 2023 — Oct 2024
External development team for Slovenská Sporiteľňa (one of the largest banks in Slovakia)
- Implemented complex multi-step banking form flows with strict validation and regulatory requirements, improving data consistency and reducing user input errors.
- Optimized Redux-based state management and asynchronous data flows in banking dashboards, reducing unnecessary component re-renders and improving UI update performance by ~11%.
- Refactored legacy React components to standardize state handling and reduce duplicated logic across multiple dashboard modules.
- Investigated and resolved production issues by tracing failures across the frontend and API layers using logs, network debugging, and error monitoring tools.
Frontend Developer
DAN.IT (e-shops) • Jul 2021 — Dec 2022
- Built responsive UIs using HTML/CSS and React.
- Integrated frontend with Node.js / Express APIs including authentication flows.
