Abdullah Basim
AI Engineer — LLM Agents, RAG Pipelines & Voice AI
I build production LLM systems — agents, RAG pipelines, and voice AI — and I ship fast. Based in Lahore, working US Eastern hours (9am–5pm ET).
About Me
AI Engineer building production LLM systems: multi-agent workflows with LangGraph and CrewAI, MCP servers that give models real tool access, and retrieval pipelines on Pinecone with semantic chunking and custom retrieval logic.
Voice AI is part of that work — agents built on Retell AI that hold a real conversation, handle a call end to end, and hand off to a human when they should.
This sits on a background in automation engineering — n8n, Make.com and Zapier orchestrating HubSpot and Stripe for CRM sync, subscription changes and billing operations, with human-in-the-loop approvals wherever a mistake would be expensive.

Featured Projects
Systems I have designed and shipped
Inbound call handling driven by an LLM — the agent answers, works out what the caller wants, and handles the call end to end instead of sending it to voicemail.
Marketing work split across specialised agents that coordinate with each other, built on CrewAI and LangGraph.
Question answering across a video corpus: content chunked semantically with overlap, embedded into a Pinecone vector database, and served through a custom retrieval and generation pipeline.
Automated complex subscription modifications with human-in-the-loop approvals, billing logic, CRM sync, and error-safe data pipeline.
Real-time Stripe → HubSpot renewal tracking with 60-day alerts for deal owners and date-calculated workflows.
Monitors trial end dates and sends automated alerts 5 days before expiration.
Daily baselines + anomaly detection + approval-based outreach when seat counts drop.
AI-based positive reply filtering, routing, mailbox monitoring, DNS error alerts, and weekly analytics.
