Setup of an n8n pipeline for generating infrastructure operators (Germany)
Usama is highly professional and has a very strong understanding of n8n. Communication was prompt and focused, with clear and precise answers to all questions. The results delivered were very helpful for our use case.
Even when our responses were delayed due to urgent matters on our side, Usama remained structured, goal-oriented, and professional throughout the project. Overall, a very good collaboration. I would definitely work with him again.

Python Developer for GenAI Chatbot
Ghufran did an excellent job auditing our GenAI chatbot. He carefully reviewed the architecture, prompt logic, and API integrations, and provided clear, structured feedback with actionable recommendations.
What stood out the most was his ability to quickly understand an existing codebase, identify performance and scalability risks, and explain complex technical issues in a simple, practical way. His suggestions were not only theoretical but also implementation-ready, which made it easy for our team to move forward.
Communication was fast, clear, and proactive throughout the project. He delivered the work on time and demonstrated strong expertise in Python and GenAI systems.
Highly recommend Ghufran to anyone looking for a reliable Python developer for AI/LLM projects, audits, or system optimization.

Lahore, Pakistan - 2:43 pm local time
✓ Top Rated AI Chatbot Developer on Upwork
✓ 50+ chatbot systems shipped in Python
✓ 10+ years in software engineering
✓ 100% Job Success
✓ $100K+ earned across healthcare, finance, SaaS, and real estate
I built an Agentic RAG chatbot for a telehealth company that cut patient support tickets by 47% in its first month, by grounding every response in their actual clinical documentation instead of a generic knowledge base. That's the difference between a real chatbot and a demo, and it's the standard I hold every build to.
What I build:
RAG chatbots with Pinecone, Qdrant, or Chroma, running on Claude, GPT-4, or Llama 3, orchestrated with n8n and Python workflows
LLM-powered document workflows that extract insights and trigger multi-step actions with built-in retry logic
HIPAA-compliant healthcare chatbots with full audit trails and self-hosted infrastructure
Fast MVPs delivered as clean, documented Python your team can maintain after handoff
I architect systems across every major LLM provider, so I'll tell you honestly whether Claude, GPT-4, or an open-source model fits your accuracy, budget, and privacy needs before you spend anything.
Tech stack: Python, Claude, GPT-4, Llama 3, LangChain, LlamaIndex, n8n, Pinecone, Qdrant, Chroma, Docker, AWS, Azure
Message me for a free 30-minute consultation. I'll architect your chatbot scope honestly before you commit to anything.
PORTFOLIO
Case 1: HIPAA-Compliant Agentic RAG Chatbot for Telehealth Intake
I built a RAG-based patient intake assistant for a telehealth platform that reduced intake call volume by 47% and cut average response time from 6 hours to under 2 minutes, using Claude, Pinecone, and n8n workflows with full audit logging for HIPAA compliance.
Skills: AI Chatbot Development, RAG, HIPAA Compliance, Python, n8n Workflows
Case 2: LangChain Document-Processing Automation for Fintech
I built an LLM-powered pipeline in Python that read incoming loan documents, extracted structured data, and routed exceptions automatically through custom workflows, recovering roughly 120 hours per month of manual data entry for a fintech client.
Skills: LangChain, Python Automation, LLM Integration, n8n, Document AI
Case 3: E-Commerce Product Recommendation Chatbot
I built a grounded product-recommendation chatbot that lifted assisted-purchase conversion by 22%, using RAG retrieval over the client's live product catalog so recommendations never went stale.
Skills: AI Chatbot Development, RAG, Recommendation Systems, GPT-4, Python
