\subsection{Current}
\cventry{2017--Present}{Systems Architect}{Unipart Digital}{Cambridge}{UK}{Unipart is a UK conglomerate specialising in manufacturing, supply chain, and logistics. Originally in the UK automotive sector but now extending to the NHS, rail, and international divisions. Unipart Digital was an internal start-up to build expertise in the modern cloud and IT sectors.\newline{}
Detailed achievements:
\begin{itemize}
  \item Successfully designed and built multiple new OpenStack environments across four datacentres.
    \begin{itemize}
  \item Planning, costing, contract negotiation, hardware sourcing, physical installation, and builds of OpenStack clusters.
  \item Regular presentations at board level, informing on cost savings and business advantages of OpenStack and FLOSS tools.
  \item Adopted an existing manually-built OpenStack environment containing a dozen or so development systems and transformed it into a production-quality private cloud, hosting hundreds of production and development systems, including: Unipart Group public websites, internally developed tools for e-Learning, Warehouse Management, and Robotics.
  \item Live migrated a hyper-converged Ceph storage system to a discrete one without downtime.
  \item Wrote a complete OpenStack deployment system (from bare metal to running environment) using Puppet and Python.
  \item Specified, wrote, and collaborated on several OpenStack DNS and network plugins (``systemcloud'' and ``openstack-publicdns'' are two FLOSS examples available on Github).
    \end{itemize}
  \item Introduced ``High Availability'' concepts to dev teams, and championed industry standard practices for distributed app development.
  \item Implemented a native-IPv6 network across the Cambridge office and all Digital Team datacentres to mitigate IPv4 exhaustion issues experienced by developers.
  \item Deployed a cost-effective HAProxy solution to work around the non-availability of public IPv4 space.
  \item Built a multi-site FreeIPA deployment containing roughly 10,000 accounts.
  \item Wrote custom Python/JS FreeIPA plugins to meet business needs.
  \item Created a SAML authentication system and provided direction to Web and application developers for integration.
  \item Promoted a ``FLOSS-first'' development environment and assisted developers in keeping proprietary information out of public code-bases.
  \item Evaluated and then introduced a fully-featured CI/CD system to the developers (Concourse CI) and helped them to migrate jobs away from an unmaintained Jenkins server.
  \item Replaced various manual hacks with maintainable tools according to developer and business requirements (plain git repos \rightarrow Gitea/Gitlab/Github, Jenkins \rightarrow Concourse, Manual mail server config \rightarrow LDAP groups, etc.).
