About Me

I'm a Senior Flutter Developer with 4+ years of hands-on experience building scalable cross-platform mobile applications. Based in Okara, Pakistan, I work remotely with clients across the globe—from startups to government institutions.

My journey started with a passion for solving problems through code. Over the years, I've evolved from a junior developer to a technical leader, shipping production apps to millions of users on the Play Store and App Store.

I believe in clean code, user-centric design, and long-term maintainability. Whether it's architecting complex backends, optimizing performance, or mentoring teams—I'm driven by impact and continuous growth.
