At ART Fintech, I develop and maintain frontend functionality for banking and FinTech systems, including credit products, payment schedules, account operations, and contract parameters.

I build dynamic forms, validation logic, and data-intensive interfaces for financial workflows, and integrate applications with backend services through REST APIs. I also work on performance optimization and reusable UI components.

Previously, at BrightVision, I developed enterprise applications with Oracle APEX and backend business logic with Oracle PL/SQL. I also optimized SQL queries and contributed to a system for the Unified Registrar of Securities.
