                 \begin{itemize}
                     \item[•] Decreased runtime from ≈ 6 hours to ≈ 40 minutes.
                     \item[•] Reduced CPU utilization from ≈ 98\% on 16 cores distributed among 4 servers to ≈ 30\% on 1 core on 1 server.
                     \item[•] Completely eliminated memory overflow exceptions.
                     \item[•] Decreased database storage by a factor of ≈ 8 while simultaneously improving data manipulation language (DML) performance.
                 \end{itemize}
                 \item Improved type safety leading to an increase in errors caught at compile time.
                 \item Serve as the resident technical expert and provide guidance to coworkers on an as-needed basis.
                 \item Found several SQL-injection bugs in both the GUI and backend.

                 \item Made most hosted services only accessible via VPN server.
                 \item Using \href{https://man.openbsd.org/OpenBSD-7.2/amd64/pf.4}{pf(4)}, greatly limit what devices are allowed to communicate with each other.
                 \item When possible, use strong public-key cryptography for primary factor of authentication (e.g., ed25519).
                 \item For services that still require passwords, use unique, random 32-byte passwords stored in hosted password manager.
                 \item Store secrets (e.g., SSH keys) on security token when possible.
