Frontend Developer at Quant Tech

Implemented a centralized Axios error-handling layer, unifying API behavior and eliminating duplicated request logic across the application. Built a reliable auto-save system for complex forms (localStorage + debounce), preventing user data loss during input. Optimized large tables and filtering workflows, reducing unnecessary API calls and improving UI performance. Refactored complex multi-step forms and modules, fixed navigation issues and increased overall reliability. Improved Pinia state architecture and application reactivity, reducing redundant re-renders and boosting UI responsiveness. Enhanced UX across forms and data tables by adding proper loading states, validation, and synchronized UI components. Reduced technical debt by cleaning and stabilizing legacy modules (forms, requests, data workflows). Streamlined component structure and codebase by standardizing architecture patterns, naming conventions, and log separation. Developed a responsive landing page based on Figma desi

Frontend Developer at Archimedes Kazakhstan

Designed modular React components (TypeScript, React, Mantine UI) for patient forms, medical records, and doctor schedules, ensuring reusability and easier maintainability. Built a scalable visit workflow engine supporting 48+ medical specialties using dynamic form generation (JSON-driven templates + Zustand state management). Implemented patient medical records module with structured storage of visit history, complaints, diagnoses, and examinations, integrated with backend via REST API. Developed appointment scheduling system with server-side filtering, search, and inline editing of doctor timetables (React Table, Zustand, optimized API calls). Introduced automated testing strategy with Jest + React Testing Library, covering visit forms, patient records, and scheduling logic — reducing regression bugs. Applied performance optimizations: reduced unnecessary component re-renders with React.memo and useCallback; introduced lazy loading of patient records and schedules. Refactored state
