I build scalable backend systems and enhance them with Generative AI to create intelligent, real-world applications.

With expertise in Django and FastAPI, I develop systems that integrate LLMs, enabling capabilities such as document understanding, AI-driven workflows, and automation.

I focus on clean architecture, performance, and production-ready solutions.

• Django, Django REST Framework, FastAPI
• REST API Design, Authentication (JWT, OTP)

• LangChain, LangGraph (basic)
• RAG Pipelines, AI Agents, LLM Integration
• OpenAI, Groq, Google Gemini

• PostgreSQL, MySQL, SQLite
• Vector Databases: FAISS, ChromaDB

• Celery, Redis (Async Tasks)
• Git, Postman, Linux
• Deployment: Render, Netlify
