About Abdullah
Python FastAPI Engineer | RAG Chatbots + AI Search | B2B SaaS
Lahore, Pakistan - 9:04 am local time
• I build production RAG chatbots and AI search that answer from your data with citations
• I also build full-stack MERN apps when you need UI + backend together
→ If your chatbot hallucinates, misses sources, or is slow on PDFs, I can fix it and ship a stable backend
AI and RAG (Main Focus)
✅ RAG chatbot, knowledge base chatbot and document chatbot (PDF, DOCX, web pages)
✅ PDF chatbot with citations and source grounding
✅ AI search, semantic search and document search inside your app
✅ FastAPI backend APIs for LLM apps (tool calling, streaming, async endpoints)
✅ Ingestion pipeline: parsing, chunking, embeddings, updates and re-indexing
✅ Vector DB integration: pgvector, Pinecone, Qdrant, Weaviate, Chroma, FAISS
✅ Hybrid search, metadata filters and reranking for better accuracy
Common Problems I Solve
✔ RAG chatbot hallucinating or giving wrong answers confidently
✔ Citations not matching the real source
✔ Weak PDF retrieval due to bad parsing or chunking
✔ High latency and high token cost
✔ Deployment issues (Docker, AWS, timeouts, retries, logging)
Python Backend Stack
🔹 Python | FastAPI | REST APIs | async
🔹 PostgreSQL | SQLAlchemy | Redis | Celery
🔹 JWT | OAuth2 | role-based access | multi-tenant patterns
🔹 Docker | AWS deployment
MERN Stack (Full Product Delivery)
⭐ React dashboards and admin panels
⭐ Node.js and Express APIs
⭐ MongoDB modeling, aggregation and performance tuning
⭐ Auth flows (JWT), role-based access and clean API contracts
⭐ CRUD, search, filters, file uploads and user management
What You Get
• Production-ready delivery, not a demo
• Clean architecture and maintainable code
• Accuracy, latency and cost control for AI features
• Clear milestones and communication
Message Me With
→ Data source: PDFs | docs | site | database
→ Expected output: chatbot | AI search | API | full app
→ Deployment target: AWS | VPS
