I have 7 years of software engineering experience, and my journey has naturally evolved from frontend to full-stack with a strong backend focus. I started with C# and .NET MVC — building enterprise web applications, working with SQL Server, understanding layered architecture and OOP principles in a real production environment. That foundation gave me a strong understanding of how backends are structured, how data flows, and why design patterns actually matter beyond theory. For the past 5 years, my primary focus has been Angular. I've built and maintained large-scale SPAs — working with complex state management using NgRx, optimizing change detection with OnPush strategy, building reusable component libraries, and managing RxJS streams in data-heavy dashboards. I've led frontend architecture decisions, established coding standards, and mentored junior developers on reactive patterns and performance best practices. More recently I've been deepening my backend work with NestJS — building REST APIs with JWT authentication, Redis caching, background job processing with Bull queues, and WebSocket-based real-time features. I've also worked with both PostgreSQL using TypeORM and MongoDB using Mongoose, which gives me flexibility in choosing the right database for the right problem.
