👨‍💻 About Me

I'm a Frontend-Heavy Full Stack Engineer from Karachi, Pakistan, specializing primarily in the MERN and MEAN ecosystems.

My strongest area is building modern frontend applications with React, Next.js and Angular, backed by scalable APIs and services using Node.js, Express.js, MongoDB and PostgreSQL.

Beyond the JavaScript/TypeScript ecosystem, I have secondary backend experience with PHP Laravel, .NET Core and Python, allowing me to work effectively across different production architectures.

I've worked on products involving:

• 🛒 Marketplaces & SaaS platforms
• 💬 Real-time chat & communication
• 📹 WebRTC video calling
• 🤖 OpenAI & AI-powered functionality
• 💳 Payment integrations
• 🔐 Authentication & authorization
• 🔌 REST APIs & third-party integrations
• 📊 Admin dashboards & data-heavy interfaces
• ⚡ Redis & real-time infrastructure
• 📱 React Native mobile development

Currently exploring LLMs, AI integrations and AI-native application architecture.
