Available to hire
Hi, I’m Waseem Khan, a senior iOS and Flutter developer with 8+ years of experience building high-performance, user-centric mobile apps. I specialize in Swift and Flutter and have a track record of delivering scalable, cross-platform solutions with clean, maintainable code that aligns with business goals.
I love crafting seamless UI/UX experiences, optimizing performance, and collaborating with design, product, and backend teams to bring ideas to life—whether it’s an EV charging management app, a VOIP calling tool, or a workforce and task management platform. I’m comfortable working remotely and across time zones to ship quality software.
