At TSIFROLAB, I develop and enhance large internal information systems using React and JavaScript/TypeScript. I work within an established production architecture, extending existing code and resolving bugs.

I’ve implemented complex business workflows, including multi-step forms, applications, and approval flows. I handle business rules and validation, and use Zustand and React state to manage data across forms and connected components.

I integrated frontend functionality for an electronic document-signing workflow that generates, retrieves, and signs PDF documents, using CryptoPro/CAdES and backend APIs. I also develop dashboards, portals, catalogs, and task registries for construction project monitoring and management systems.

At SBERMARKET, I developed features for a corporate learning and development platform, including learning-progress tracking, certificates, and knowledge assessments. I also contributed gamification features such as points, ratings, leaderboards, and integration with the corporate rewards platform.
