Work Experience

Senior Software Engineer

2013 - PRESENT

Cloudbase Solutions

Heavily contributed to various OpenStack projects, including Nova, Cinder, Neutron, Manila, and Glance. My task was introducing and maintaining Windows support for various Microsoft solutions, such as Hyper-V or Storage Spaces.
Provided Windows support for Ceph clients. This required porting the userspace code, also implementing a Windows Storport Miniport kernel driver in order to attach RBD images.
Contributed to various virtualization tools, such as Crosvm, Qemu/Android emulator as well as some internal ones.
Helped to maintain our third-party Windows OpenStack continuous integration testing system, which verifies all incoming patches for Nova, Cinder, Neutron as well as a few other projects. Also implemented a CI testing system for Android Emulator.
Provided Windows MSI installers for our products, making them easier to consume.
Provided Docker containers to help packaging binaries and simplify the build process.
Made a Kubernetes contribution, allowing Persistent Volumes to be used when running on top of Hyper-V OpenStack environments.
Implemented a coding challenge app that was used as part of our recruiting process as well as a hackathon.

Experience

OpenStack

The most commonly used open-source cloud computing platform. I was working on integrating Microsoft technologies such as Hyper-V, S2D, or the OVS Windows port. I heavily contributed to projects such as Nova, Cinder, Neutron, Glance, or Manila.

I introduced and maintained a few OpenStack drivers, also serving as "Winstackers" project team lead.

Ceph Storage

https://github.com/ceph/ceph

Probably the most commonly used distributed storage system. I ported the Ceph clients to Windows, ensuring that RBD, as well as CephFS, could be used natively, without the need of a proxy such as the iSCSI gateway. In order to be able to attach RBD images, we had to implement a Windows kernel driver called WNBD.

WNBD driver

https://github.com/cloudbase/wnbd

A Windows Storport Miniport kernel driver, mainly used for attaching Ceph RBD images. It also supports the NBD protocol, allowing it to be used in a variety of scenarios like attaching any virtual disk supported by Qemu and leveraging the qemu-nbd service.

Libwhp

https://github.com/insula-rs/libwhp

A Rust library providing Windows Hypervisor Platform API bindings. Its main goal is to allow implementing secure, lightweight VMMs (also known as hypervisors) using Rust. The project is tied to the Rust-VMM initiative.

PyMI Library

https://github.com/cloudbase/PyMI/

A CPython extension written in C++ that exposes the Windows Management Instrumentation (WMI) interface, using the low-level Windows Management Infrastructure (MI) API.

PyMI provides an extremely fast alternative, drop-in replacement to the pywin32/DCOM based library.
