Muneeb Khan

My Portfolio

Hello! My name is Muneeb Khan. I specialize in architecting scalable SaaS platforms, e-commerce systems, mobile applications, AI-driven products, and distributed systems across the fintech, marketplace, Web3, and enterprise software industries, as well as modern AI-augmented software workflows.

My passion for programming began at a young age, experimenting with code and exploring network structures, which naturally evolved into a full-stack engineering career spanning over 8+ years.

Throughout my journey, I have had the privilege of leading distributed engineering teams of 10–15 engineers, establishing strong engineering standards, and designing resilient, high-performance platforms serving hundreds of thousands of users across both web and mobile ecosystems.

I have built and delivered cross-platform mobile applications alongside web systems, including React Native-based apps integrated with real-time booking, payments, messaging, and location-based services for marketplace-style platforms.

In recent years, I have become an early adopter and specialist in building AI-native systems. I leverage LLM integrations, custom MCP (Model Context Protocol) servers, and automation pipelines to design intelligent engineering workflows that significantly accelerate product development and delivery.

Beyond my professional work, I value creative exploration through travel, photography, and open-source contributions. Notably, I contributed to the 360 Google Street View mapping of Karachi, helping over 42 million people navigate the city.

I am highly analytical in system design and performance optimization, with a strong ability to identify and resolve complex architectural bottlenecks efficiently.

I am always seeking challenging, high-impact opportunities where I can continue advancing distributed systems, AI-driven engineering, and large-scale software and mobile architecture.

Over the years, I've developed deep expertise in a broad set of technologies, including:

React.js / Next.js

JavaScript / TypeScript

Node.js / NestJS

React Native / Hybrid Apps

PostgreSQL / MongoDB

GraphQL / REST APIs

TailwindCSS & SSR

AWS / Cloud Infrastructure

Docker / Kubernetes

Firebase / Mobile Services

WebSockets / Realtime

AI Agentic Workflows

MCP Servers & LLMs

Microservices & Redis
