As a Unix Server Administrator at Murdoch University I accumulated two decades of experience in supporting diverse technical teams in the Tertiary Education Sector. More recently, I have experience in maintenance of cloud infrastructure in AWS, within the resources sector.
Expertise includes performance testing, design and implementation of integrations between services, and educating staff on the finer points of regular expressions, SSL, and application configuration.
Conceptual, analytical skills and strong customer service skills combine to create a supportive network environment where systems are maintained effectively to deliver a secure, reliable operating environment. My objective is to continue to bring sensibly-implemented technical expertise to the IT sector.
- linux server deployment and administration.
- server application configuration and administration, including database, backend and frontend services.
- experience with cloud tools and services, including Terraform, GitLab, and AWS.
- system monitoring and performance analysis.
- scripting, for automation, analysis, etc. Python, Perl, shell scripts.
- analysis and troubleshooting of complex systems.
- attentive to detail, security-minded, succinct.
- writing accessible and usable documentation and other communications.
- diligence and a desire to learn and improve.
Modis is a business that provides IT and Engineering services to a range of government and non-government organisations.
As a cloud engineer I worked with existing applications to improve their reliability, security and performance. I also contributed to projects that created new infrastructure.
Murdoch University is a Perth-based university with 23,000 students and 1,700 staff, with campuses in Murdoch, Rockingham, Mandurah, Perth, Dubai, and Singapore.
As a Unix Server Administrator I was responsible for building and maintaining the OS on large portions of the university's Linux server fleet, performance testing, design and implementation of integrations between services, and problem troubleshooting.
- maintain server operating systems, including monitoring and patching.
- configure servers from raw metal (or blank VMware VM) all the way up to running services (usually apache).
- write and maintain integrations between applications.
- SSL certificate renewals.
- performance testing of systems involved in class signups (source of peak system load).
- assist other staff with their sysadmin tasks, problem diagnosis, etc.
- participate in the migration of systems from on-prem VMware to Azure cloud.
Substantial progress (abandoned due to personal circumstances)
- IaC: Terraform.
- source code management: GitLab, Bitbucket, CI/CD pipelines.
- AWS: good working knowledge of S3, SQS, SNS, IAM, Lambdas and step functions.
- azure: exposure to the azure portal and APIs, walinuxagent, application gateway.
- primarily linux, but also exposure to Solaris and AIX. RHEL5 through RHEL9, Debian, RHEL/CentOS, Ubuntu.
- advanced Debian administration: dpkg, apt, package repositories.
- virtual servers: VMware, disk and volume management, LVM.
- networking: firewalls (iptables, iproute2), multi-interface routing.
- also: JVM monitoring, log collection and analysis.
- virtualisation: vmWare, libvirt.
- I know regular expressions.
- web: apache (mod_rewrite, mod_proxy, mod_proxy_balancer, mod_macro, mod_fastcgi), nginx, reverse proxies, SSL certificates.
- mail: MTA configuration (sendmail, exim, postfix, saslauthd).
- system programming: perl, python, regular expressions, sqlite.
- network protocols: TCP/IP, SMTP, HTTP, SSL, SMTP, IMAP.
- integrations: Finance, Callista, HR.
- monitoring: nagios, mrtg, munin, smokeping.
- performance testing: creating better real-time monitoring capability, interpretation of testing results.
- languages: Perl, shell script, Python. Exposure to PHP, Java, Javascript. Have also dabbled in Powershell and Javascript.
- data formats: CSV, JSON, YAML.
- workflow: subversion, git, Debian package development and repository maintenance. Regular user of Github/gitlab/GOGS.
- web: this resume is a Markdown document converted to HTML (though if you're reading this on Seek, then you're probably looking at a (probably out of date) PDF version that doesn't contain the benefits of my hand-written CSS...)
- keen interest in achieving best practices: correct use of firewalls, strong desire to keep software up to date, awareness of what techniques, strategies, protocols, etc to prefer and to avoid.
- Precise and succinct communicator.
- Writer of accessible and usable documentation.
- infrastructure: physical server installation and cabling, fault diagnosis, liasing with vendor engineers.
- tape library: backup tape handling, documentation.
- monitoring infrastructure. Filled a performance visibility gap by configuring munin and smokeping to monitor systems. This allowed creation of historical performance data across a large part of the server fleet.
- SSL certificate monitoring. Due to lack of SSL monitoring (for both expiry and misconfiguration), I wrote a tool that collected certificate information from web and other SSL-enabled services for reporting purposes. Was very useful when QuoVadis unexpectedly revoked one of their intermediate certificates.
- attention to detail.
- adherent of the KISS principle. Simplicity means reliability and maintainability.
- clean WA C class driver's license.
- former State Emergency Service volunteer, 2006-2012.
Congratulations on reading this far! I am grateful! Assuming you didn't cheat by just skipping straight to the end, that is...
Anyway, in my spare time I enjoy photography (taking photos, and, eventually, postprocessing them afterwards), Minecraft (both as a player and server admin).
