Rockstar🎓
Top SchoolEdwin Török is a Unikernel Engineer with 26 years of systems and open-source experience, currently working at Tarides and previously shaping hypervisor and cloud tooling at Citrix/XenServer. He blends deep systems programming in C, C++ and OCaml with expertise in compilers, distributed systems, and performance engineering, having contributed to projects like LLVM, Xen, OCaml and the ubiquitous Pandoc and Doom Emacs ecosystems. A longtime open-source advocate, he has a track record of pragmatic fixes—from LLVM test-suite build issues to Xen event-channel optimizations and ClamAV bytecode architecture—that improve reliability across toolchains and runtimes. He also co-founded Skylable to commercialize private cloud storage, showing an ability to turn low-level engineering into product-focused solutions. Based in the Greater Cambridge Area, he pairs rigorous academic training from Politehnica University of Timisoara with hands-on work across kernel tracing, VM management (XAPI/Xen), and OCaml tooling.
