About & Summary

Building intelligent, scalable, and production-ready software solutions with a strong foundation in backend architecture and real-time systems.

I am an AI & Backend Developer with hands-on experience in building scalable REST APIs, real-time systems, and database-driven applications using Python, FastAPI, PostgreSQL, and WebSockets.

My background includes a strong foundation in backend architecture, asynchronous programming, and system design, with a growing focus on LLMs, Retrieval-Augmented Generation (RAG), and AI-powered applications.

Backend Architecture

Designing RESTful APIs, WebSockets, OAuth2/JWT authentication, session management, and asynchronous connection handling.

AI & LLM Systems

Applying prompt engineering, embeddings, RAG concepts, vector search, and semantic search in modern Python backend stacks.
