PROFESSIONAL EXPERIENCE
Tyntec 03/2021 – present
Frontend Developer
Worked in several teams during the past 3 years:
Mental CRM Team:
• Developed a doctor profile management system. This included a client report
viewing and data visualization interface (income dynamics, number of clients,
sessions) which allowed for easier progress tracking.
• Together with the team lead, developed the application from scratch using
Feature-Sliced design architecture, which allowed free creation of new
functionality. This lowered the threshold for new developers to enter the project;
• Optimized performance of frequently used components by utilizing useMemo and
useCallback hooks, reducing unnecessary re-renders and improving application
responsiveness.
• Implemented a scheduling calendar for doctors with drag-and-drop and filtering
features that allowed therapists to easily manage their appointments.
• Implemented component-level lazy loading using React.lazy and Suspense, which
reduced the JavaScript bundle size by 30% and improved initial load times.
• Mentored less experienced colleagues, supporting their professional growth and
knowledge sharing within the team.
Administrative Panel Development Team:
• Implemented a CI/CD pipeline for automatic test execution. This ensured that the
code was always tested and ready for deployment.
• Implemented and configured eslint and prettier in the project, providing a general
code style, which increased code readability and simplified code maintenance.
• Worked extensively with Material-UI to design and implement custom components
and user interfaces, enhancing consistency, responsiveness, and usability across the
application.
• Developed 20+ data tables with Ag-Grid and TypeScript, optimizing user
interaction with product data through filtering, sorting, and searching
functionalities.
• Added 25+ forms using React Hook Form in various tables to manage
administrative data.
• Participated in regular daily meetings, retrospectives, web demos, and one-on-one
meetings.
