Rockstar🎓
Top SchoolMischan Toosarani-hausberger is a systems-focused software engineer and founder with 10+ years building production-grade embedded image-processing and computer-vision systems, now leading AboveVacant to improve run-time introspection for hardware-constrained deployments. He combines hands-on expertise in firmware, gateware, FPGA-based pipelines and host drivers with a strong background in real-time optimization, camera calibration and tooling for production glasses and stereo sensors. Previously he led architecture and team-building efforts at Viewpointsystem and IVISO, bootstrapping engineering teams and shipping low-latency, sensor-integrated products. An active open-source contributor, he has improved observability in well-known projects like PowerDNS and the sentry-native SDK by implementing robust metrics and crash/session handling. Mischan’s work sits where algorithms meet physical constraints—he designs tooling to reveal what’s happening at run-time rather than relying on ad-hoc hacks, driven by a practical obsession for human-centered introspection. Based in Styria, Austria, he blends academic training in digital arts and telematics with pragmatic, production-first engineering.
