1. Skills System Integration Across Legacy Modules (Team Project) - 09.2023 — 12.2024: ● Contributed to the integration of the company’s internal skills repository (e.g., C1 English certification) into legacy Talentsoft modules, ensuring consistent and visible skill data across the platform. ● Integrated React 16 components into a legacy .NET application, enhancing UI/UX while maintaining backward compatibility. ● Developed a data mirroring system using SQL stored procedures to synchronize skill-related data from modern services to older modules, improving cross-application communication and reliability. ● Resolved complex accessibility issues (e.g., keyboard navigation, screen reader support) using Axe DevTools and inclusive UX principles. ● Wrote test-driven, production-ready code using Jest (frontend) and NUnit (backend); supported by Jenkins-based CI/CD workflows. ● Participated in agile ceremonies and technical design reviews, contributing to continuous delivery and rapid iteration cycles. 2. Employee Data Comparison and Validation Tool (Solo development, supervised) - 09.2022 — 09.2023: ● Developed a tool to compare employee data between legacy and modern applications, detecting discrepancies in data sets such as personal information, contracts, and roles. ● Implemented a searchable comparison system that allowed HR users to check employees by name or employee number using autocomplete and debounced search input. ● Built a detailed view to display the necessary legacy-side actions (add, update, or remove data) for each flagged employee, streamlining the data reconciliation process. ● Delivered a full Figma implementation in React.JS and .NET under the guidance of the lead developer, with reviews and validations by the wider team. ● The project was delivered to deployment, resulting in a 13% increase in adoption during the first quarter after launch.

● Developed an app to streamline jury processes, reducing the average evaluation time for stand artists from 2 weeks to just 3 days. ● Addressed jury challenges in assessing application quality and authenticity by integrating a voting feature with a confidence meter. Applications flagged with a confidence score above 50% were accurate 76% of the time, improving decision reliability. ● Reduced website downtimes by 30% by migrating hosting services to a more reliable provider. ● Maintained and upgraded WordPress-based websites and forums, ensuring security by addressing vulnerabilities through dependency updates. ● Researched and implemented open-source tools for Jonetsu, the association’s convention, optimizing cost-efficiency and functionality.
