Software Engineering student at Astana IT University (class of 2027) and a frontend-leaning full-stack developer based in Astana, Kazakhstan. I build production-grade web applications end to end: typed React frontends, Node.js/NestJS and Spring Boot backends, PostgreSQL data layers, and containerized deployments with Docker and nginx.
Recent work includes a public-sector platform for the Financial Monitoring Agency that passed a formal security audit with zero critical findings, a coding contest platform used by 100+ university students, and a real-time locomotive telemetry dashboard for KTZ delivered in a 24-hour hackathon as team captain.
I care about shipping software that is secure by default, fast in production, and maintainable by the next engineer who touches it.

- Built a production-ready bilingual (Kazakh / Russian) public-sector SPA in React, TypeScript and Tailwind v4, consolidating financial risk maps, analytics and citizen complaint submission into a single platform.
- Passed a formal security audit with zero critical findings by implementing CSP, HSTS, CSRF protection and a centralized API client with XSS-safe rendering throughout.
- Containerized the application with a multi-stage Docker build and nginx, adding gzip compression, immutable asset caching and SPA routing fallback for zero-config environment deploys.
