🚀 About Me

I'm a Backend & AI Engineer with 8+ years of experience building highly available, scalable backend systems for educational and financial platforms.

My work focuses on event-driven architectures, large-scale integrations, and AI-powered automation — turning complex, manual processes into reliable, automated systems used by thousands of users in production.

I currently work extensively with C#, JavaScript (Node.js/NestJS), Python, Azure, AWS, and applied AI (LLMs & RAG).
