EXPERIENCE
Fullstack Developer — Personal Projects (Self-Taught)
Developed features from scratch, including several authentication
approaches: using JWT with Refresh Tokens as well as httpOnly
cookie-based sessions. Implemented Google OAuth login, handled
secure token storage and processing on the backend (NestJS), and
integrated it with the frontend (Next.js). Designed and connected REST
API with the client using TanStack Query, ensuring secure routes,
token refresh logic, and proper session flow. While working on
[відкрити контакти](див. вище в блоці «контактна інформація») features, I’ve analyzed third-party codebases, discovered issues in
OAuth logic, and improved my understanding of real-world
architecture and integration patterns.

EDUCATION
Self-Taught Developer
Since 2022, I’ve been studying web development through hands-on
@x_moonl1ght_x practice and working with real-life tasks and documentation. Focused
deeply on authentication (JWT, OAuth), REST API architecture, and
fullstack development (frontend + backend). Additionally, I explored
OBJECTIVE open-source code, learned common design patterns, and mastered
production tools like TypeScript, NestJS, Next.js, and more.
I’m looking to join a team where I can grow as
a developer, work on real-world tasks, and COMMUNICATION
contribute to a meaningful product. My goal is I’m confident in communicating clearly and asking well-formed,
to evolve into a strong fullstack engineer with a specific questions. When facing issues, I first analyze the situation and
focus on architecture, code quality, and secure formulate hypotheses before asking for help. Working with other
development practices. developers helped me learn how to explain technical topics in simple
terms and find common ground even in complex discussions.
