I'm a Computer Science & Engineering graduate passionate about building backend systems, REST APIs, and AI-powered applications using Python.

I enjoy turning ideas into practical software — from Django REST APIs and PostgreSQL applications to LLM and RAG-based systems.

• 🐍 Build applications with Python
• 🌐 Develop REST APIs using Django & Django REST Framework
• 🗄️ Work with PostgreSQL, MySQL & SQLite
• 🤖 Build AI/ML applications
• 🧠 Develop LLM & RAG applications
• 🔎 Work with embeddings, vector databases & semantic search
• ⚡ Explore FastAPI & Flask
• 🐳 Learn and apply Docker & deployment
• 🔧 Use Git & GitHub for version control
