Rockstar🎓
Top SchoolAndriy Tkachuk is a systems software engineer with 20+ years of hands-on experience and eight years focused on distributed storage systems, currently working across Seagate and Wasabi-related projects from Portsmouth, UK. He has deep expertise in CORTX Motr and Ceph integrations—implementing a Motr Storage Abstraction Layer for Ceph RGW, fixing memory leaks, and optimising performance and HA subsystems for exascale object storage. A pragmatic tech lead and mentor, he combines low-level systems programming with production troubleshooting for Lyve Cloud object storage and durability investigations. Trained as an engineer in radiophysics, electronics and automation, he brings a strong analytical background that helps him bridge hardware-aware performance tuning and large-scale distributed design. Notably, his contributions touch one of the most prominent open-source storage projects (Ceph), demonstrating both community-oriented engineering and attention to operational robustness.
