Elias Valkonsky

Full-Stack Architect & Technical Advisor

I'm a 20-year-old developer. I've been programming since I was 12, evolving from simple C# console apps to designing resilient, high-performance web ecosystems.

Today, I specialize in modern Angular, Svelte, Nx, and NestJS. I evaluate emerging build tools to guide seamless technology migrations, design robust distributed APIs, and build scalable, containerized CI/CD pipelines that accelerate development velocity while enforcing strict architectural consistency.
