About Hasan
Agentic AI & Automation Engineer | Scalability Expert
Lahore, Pakistan - 2:06 pm local time
As a Senior Software Architect with over a decade of experience, I specialize in building intelligent AI agents that deliver transformative business results on an enterprise scale.
My unique expertise lies at the intersection of advanced AI and robust, scalable system architecture. I don't just build AI prototypes; I architect sophisticated, automated systems using LangChain, LangGraph, and Python that are built to handle massive, real-world demands.
My background is in designing and scaling complex, high-traffic applications. As a Backend Architect, I successfully scaled a leading ride-hailing platform from 15k to 300k rides per day, giving me a deep, practical understanding of building systems that perform under extreme load. I now apply that same architectural rigor to the world of AI.
Here's a snapshot of the results I deliver:
🚀 90% Reduction in Customer Support Workload: Architected a multi-agent AI system that automated the vast majority of support queries.
🚀 CSAT Score Increase from 30% to 87%: Transformed user satisfaction by providing instant, accurate AI-driven responses.
🚀 100 Million Messages/Minute: Designed and implemented a real-time data pipeline capable of handling enterprise-level event streams.
Whether you are a startup aiming to launch a groundbreaking AI feature or an enterprise looking to automate complex workflows, my expertise in system design ensures your solution will be intelligent, resilient, and built for growth.
My preferred toolkit includes LangChain/LangGraph, Python, LLMs, FastAPI, and Vector DBs (Qdrant), all underpinned by my deep experience in system design for large-scale data handling.
Let's connect to discuss how I can help you build an AI solution that delivers measurable impact.
