About

Who's behind the terminal.

Experienced Software Engineer with 7+ years of end-to-end product development expertise across mobile, web, and back-end platforms. Led cross-functional teams to deliver high-impact applications, including a hiking navigation app (The Pekoe Trail), an AI-driven golf coaching tool (Swingzen), and a large-scale loyalty platform for QatarEnergy. Skilled in React Native, NestJS, Node.js, and cloud platforms (Azure, AWS), with a strong grasp of infrastructure-as-code, CI/CD, and scalable system design.

I thrive on solving complex technical challenges and building systems that scale. From mobile apps to cloud infrastructure, I enjoy the full spectrum of software development.

My approach combines technical excellence with pragmatic problem-solving — always focusing on delivering value while keeping code quality and system reliability intact.

Outside of work, I'm a hobbyist photographer exploring the world through my lens, one frame at a time.
