Introduction

About Me

Who I Am

Transforming Ideas into Intelligent Digital Solutions

I'm a senior full-stack engineer based in Lahore, Pakistan, with 5+ years building production SaaS platforms and 2+ years shipping agentic AI systems in production.

I own full-stack delivery across large polyglot microservices platforms — 30+ repos spanning core SaaS, geospatial data pipelines, and AI outreach — and build AI agents on the Anthropic Claude Agent SDK, OpenAI Agents SDK, and MCP, embedding them in both the product and the engineering workflow.

Beyond client work, I mentor students at PIAIC and contribute to Panaversity's open-source agentic-AI curriculum (4.2k★ on GitHub) and "The AI Agent Factory" book, read by 22,000+ learners. I'm open to remote roles and relocation.
