    {CTO}
    {July 2018 -- present}
    {\bodytext{All of the work that I did as a senior software engineer, plus
               the pleasure and privilege of working with a diverse team of
               skilled engineers, taking responsibility for all of our work.
               \begin{itemize}
               \item Wrote a portfolio management system in Pharo Smalltalk for
                     a Global 500 company that is able to visualize thousands
                     of projects and tens of thousands of people working on
                     them. We were able to help guide the budgeting through
                     making KPIs and other facts about the company visible.
               \item Helps in hiring and onboarding fantastic engineers. We’re a
                     small company of mostly senior developers with a passion
                     for what we do, and we always search for like-minded
                     people.
               \item Takes responsibility for the work that we do, and helps
                     guide the decision process for our tooling and
                     infrastructure. We’re a truly democratic company and no
                     single person can claim to know everything, so I ask a lot
                     of questions!
               \item Talks to clients on a regular basis about expectations,
                     performance, and a mixture of nitty-gritty technical
                     details and high-level budgeting topics.

    {\bodytext{Built software for a diverse set of clients,

               \begin{itemize}
               \item Wrote an API for BIRD, an internet routing
               daemon, in Go, with microsecond latency
               and high configurability. It is currently being
               used by a variety of Internet Service Providers.
               \item Audited software systems written in Java
               and Python for faults and helped find security
               holes. This included communicating these issues to
               the teams in a blameless and constructive way.
               \item Built internal and Open Source tooling using
               Python and Django; C; and JavaScript for the company
               to help track clients and projects. This freed up
               time otherwise spent on synchronization between
               departments.
               \item Built Customer and Operations portals and help
               desks using Javascript and React; Python and Django;
               and Go that helped speed customer onboarding up from
               days to hours.
               \item Worked with Python and NumPy to speed core
               sections of a client’s code base used for calculating
               resource availabilities up by a factor of 5-7.

               \begin{itemize}
               \item Maintained and extended customer-facing websites written
                     in JavaScript and Angular. Split up applications into
                     modules, drastically reducing onboarding time of other
