About Me
My journey from frontend curiosity to backend expertise, driven by a passion for building systems that solve real problems.
My Story
I started my development journey with a curiosity about how websites work, diving into React and frontend development. But as I built more applications, I became fascinated by what happens behind the scenes - the APIs, databases, and systems that power user experiences.
That curiosity led me to backend development, where I discovered my true passion. There's something deeply satisfying about architecting systems that handle complex business logic, secure sensitive data, and scale to serve thousands of users.
Today, I specialize in building robust backend systems with Node.js, designing secure authentication flows, optimizing database performance, and creating APIs that developers love to work with. Recently, I've been diving deep into AI integration, working with LLMs and prompt engineering. I'm based in Lahore, Punjab, Pakistan and always excited about the next technical challenge.
