Muzammil delivered our OTT platform on time and exceeded every expectation. His knowledge of ExoPlayer and Firebase is unmatched. He also built our AltaPlay casting app — supporting DLNA, LG, AirPlay, and Chromecast — a genuinely impressive piece of engineering. Highly recommend for any streaming project.
Outstanding Flutter developer. Built our payment app from scratch in 8 weeks. Clean code, great communication, and zero post-launch bugs. Muzammil understands the business side too — not just the technical. That's rare. Will hire again without hesitation.
Muzammil helped us migrate our legacy Android app to modern Kotlin architecture. Performance improved by 40% and our team can now maintain it easily. Professional, thorough, communicates clearly throughout. Highly recommended for any Android migration or new build.
