Cross-Form Factor Call UI – Modern Telephony Experiences for Windows Devices

Microsoft | Windows

As the primary engineer for call control UX, I led the design and development of modern calling interfaces across both experimental and mainstream Windows devices. This included building a fully functional telephony experience for Andromeda, Microsoft’s tented dual-screen device, where I implemented core controls like mute, hold, DTMF, and hang-up—all tailored for a flexible dual-display form factor. In parallel, I architected and delivered the new calling UI for Windows desktop—bringing a polished, standards-compliant phone call experience to the Windows PC platform. This work required close collaboration with PM and Design to ensure consistency with Windows UX guidelines and accessibility expectations, especially given the scale of the desktop user base. Together, these efforts pushed forward the Phone Link platform’s vision of seamless, native call integration across form factors—laying the groundwork for future extensibility and cross-device continuity.
