Senior🎓
Top SchoolBjörn Kempen is a Senior Software Engineer with 11+ years at Google, where he has contributed to real-time communication and conferencing products including Google Talk, Hangouts, Chromebox for Meetings and Hangouts Meet. Based in Stockholm and trained with an MSc in Computer Software Engineering from Luleå University of Technology, he blends systems-level thinking with product-focused delivery. Outside work he contributes to the well-known MAME emulator as an embedded systems/IoT developer, improving blitter timing, video interrupts and flash emulation for classic arcade hardware. That mix of large-scale, user-facing product experience and low-level hardware emulation gives him a rare ability to troubleshoot across the full stack—from timing-sensitive firmware to distributed cloud services.
