About Me
I build AI agents, end to end: the planning and memory that make them reliable, the tools they call through MCP, and the production systems they run on. I'm a Full Stack AI Engineer in Lahore, Pakistan, with over 4 years of experience, working with LangChain, LangGraph, LlamaIndex and RAG, and I have shipped MCP connectors for Claude and ChatGPT. I like owning projects end to end, from API design to production support: I solely built Retell AI's CRM integration platform, and my work spans FinTech suites, the RedxChess engine (ELO 3640) and large-scale UK property platforms.
WHAT I DO
Agentic AI Engineering
AI agents that plan, use tools & remember
I design agents as systems: LangGraph planners that break work into steps, RAG and memory so they work from real data, MCP tools for Claude and ChatGPT so they can act, and tracing so every run can be checked.
Skillset & tools
Agent Infrastructure
The production systems agents run on
Specializing in multi-tenant system design, CRM and platform integrations (Salesforce, Zoho, Slack, Epic FHIR), secure OAuth2 and webhook flows, real-time communication (Twilio/Socket.io) and payments (Stripe/PayPal/Plaid).
