Sultan Mehmood. Computer Science student at COMSATS Islamabad (CGPA: 3.52/4). I specialize in production backend engineering (Go, Python, FastAPI, Kafka) and applying machine learning. My expertise includes building multi-agent AI verification pipelines, explainable AI (SHAP/LIME), computer vision (OpenCV), and full containerization (Docker). I bridge complex logic with scalable architecture, delivering deployable, high-fidelity systems grounded in real-world application, such as my experience with identity verification platforms like NeuroVerify.
My Portfolio
FAQ
What frameworks do you use to build AI agents?
I specialize in code-first frameworks including LangGraph, LangChain, CrewAI, and AutoGen, backed by Python and FastAPI. I build stateful, resilient microservices rather than brittle no-code automations.
Why use LangGraph instead of simple LangChain or no-code tools?
LangGraph allows cyclic graphs, persistence, and state management. Unlike simple chains that fail silently if an LLM returns unexpected JSON, LangGraph agents can retry, route errors, inspect state, and pause for human validation.
How do you prevent hallucinations in RAG systems?
I implement multi-tier guardrails: strict prompt containment, source citation validation, confidence-score thresholds, and fallback routines when retrieved context is insufficient to answer reliably.
Do I need to provide my own LLM API keys?
Yes. You will provide your API keys (OpenAI, Anthropic Claude, Google Gemini, or Groq) so all inference costs remain under your direct billing. I will guide you on setting up cost limits and rate-limiting safeguards.
Can you integrate the agent into my existing database or application?
Yes. I build clean REST APIs using FastAPI and can connect agents to PostgreSQL, MongoDB, Redis, vector databases (Pinecone, ChromaDB, Qdrant), and third-party SaaS APIs.
What do I need to provide before ordering?
Please message me first with: (1) Your business goal or workflow description, (2) The input data sources (docs, database, API), and (3) Expected outputs. We will align on architecture before you place an order.
