Passionate about crafting intelligent AI-driven systems and robust, high-performance backend solutions.

🚀 My Core Focus:

• 🤖 AI Engineering:
  • Retrieval-Augmented Generation (RAG) & Agentic Systems (Tool Calling, CrewAI, MCP)
  • LLM Fine-tuning & Prompt Engineering
  • Advanced Image Processing (ComfyUI Workflows, LoRA Model Training)
  • Vector Databases (Qdrant, Faiss, Chroma)
• ⚙️ Backend Development:
  • High-performance RESTful APIs (FastAPI, Spring Boot, ExpressJS)
  • Microservices Architecture & Scalable System Design
  • Database Management (SQL, NoSQL, GraphDB - Neo4j)
  • DevOps & CI/CD (Docker, AWS, Cloudflare, GitHub Actions)

🛠️ Tech Stack Highlights:
