# Udbhav Bhatnagar > Staff Software Engineer @ Apple | OS & AI Infrastructure | Ex-Meta (WhatsApp · Instagram · Portal) | Android since 2010 Location: San Francisco Bay Area, United States Profile: https://flows.cv/udbhav I build the systems that make devices feel magical — OS-level infrastructure where milliseconds matter and billions of users are affected by every decision. Currently at Apple as a Staff Software Engineer on the Operating Systems team, I develop platform-level components that accelerate AI capabilities across the full breadth of Apple hardware. My work enables product teams to ship features that feel genuinely new — the kind that make people reach for their phones without knowing exactly why. Before Apple, I spent nearly 8 years at Meta shipping at scale across some of the world's most-used apps. I worked on video infrastructure for Instagram (leading the ExoPlayer 2 migration and ABR adoption), WhatsApp's Android efficiency (battery, memory, disk), WhatsApp Payments infrastructure, and Portal identity systems that brought WhatsApp to a new form factor. I know what it means to ship features to 2 billion users and to be paged at 2am when something breaks. I've been building on Android since 2010 — before most of the Android ecosystem existed. I've also shipped on iOS/Apple platforms, Windows 8, and BlackBerry. That breadth means I think in systems, not silos. What I care about: elegant architecture, developer leverage, and the intersection of OS primitives and AI. I'm drawn to teams solving hard problems in the platform layer where the leverage is highest. ## Work Experience ### Staff Software Engineer (Operating Systems) @ Apple Jan 2022 – Present | Cupertino, CA - Architect and ship OS-level platform components that expose AI capabilities to product teams across iPhone, iPad, Mac, and emerging Apple device categories. - Collaborate cross-functionally with infra, framework, and product teams to define the right abstractions; influence technical direction at the platform level. - Operate at Staff scope: Technical Leadership, raising quality bar and mentoring engineers across multiple teams. ### Software Engineer (Android) @ Facebook Jan 2014 – Jan 2022 | Menlo Park, CA - WhatsApp Android: Led initiatives to reduce app data usage and improve resource efficiency (battery, memory, disk) for 2B+ users; shipped WhatsApp Payments infrastructure on Android. - Instagram Video Infrastructure: Drove adoption of ExoPlayer 2 and Adaptive Bitrate (ABR) streaming improvments — meaningfully improving video quality and reliability at global scale. - Portal Identity: Brought WhatsApp to Portal devices, designing the identity and auth infrastructure for a new hardware form factor. - Facebook App Infrastructure: Worked on OEM partnerships and upgrade infrastructure supporting the full Facebook Family of apps; contributed to initial Oculus mobile products. ### Android Engineer @ American Express Jan 2013 – Jan 2014 | Greater Phoenix Area Prototyped Android features in AmEx's Mobile Centre of Excellence; established tooling and best practices for internal Android teams. ### Mobile Software Engineer @ Deloitte Digital / Ubermind Jan 2013 – Jan 2013 | Denver Metropolitan Area Worked on Android Projects out of the Denver Studio. ### Software and Mobile Engineer @ AirWatch Jan 2012 – Jan 2013 | Atlanta Metropolitan Area Built Android and Windows 8 components for AirWatch's MDM and enterprise content management platform. ### Software Developer @ Research In Motion Jan 2011 – Jan 2012 | RTP Shipped enhancements and critical fixes for core smartphone PIM apps (Calendar, Contacts, OTA Sync, Phone) on the BlackBerry OS — early career foundation in mobile platform engineering. ### Graduate Student @ North Carolina State University Jan 2009 – Jan 2010 | Raleigh-Durham-Chapel Hill Area Specialized in Network Software, including programming in OS, Security, IP, Android, Ruby. ### IT Intern @ Accreditation Commission for Health Care, Inc.
