Who I Am

I'm a Backend Developer with nearly 2 years of experience specialized in CRM systems, multi-platform chatbots, and AI-powered applications. I possess strong logical thinking and a focus on system optimization to build robust solutions.

I've successfully built RAG-based chatbot systems for document retrieval and intelligent responses. My experience ranges from developing CRM modules to architecting real-time messaging features and caching mechanisms.

I'm looking to further grow in backend development, system architecture, and real-world AI applications. I thrive on solving complex problems that require a combination of analytical skills and modern technology.
