Hi, Iβm Ian van der Linde (hence @Ianvdl and ivdl.co.za). In my current role, I am responsible for running PostgreSQL 24/7 for downtime-sensitive applications in high availability, and working on automation and CI/CD for infrastructure using Puppet and Ansible, and performance monitoring and tuning using a custom PostgreSQL extension and PowerBI.
Previously, I was responsible for full stack Python/Django software development (including all aspects of HTML/CSS/JS on the frontend), high performance PostgreSQL database administration and Linux system administration (on-premises in the form of bare-metal and containerised applications, and Microsoft Azure cloud services). I also worked with colleagues to establish patent analysis as a key function of the team.
I am a certified Linux systems administrator and software developer with experience in automation through version control (Git and SVN), orchestration (Rundeck and Ansible) and configuration management (Puppet), programming mainly in C# with ASP.NET and Python with Django. I have also worked in a high performance computing environment in all areas of hardware and software installation and configuration.
I have specialised experience in DSpace repositories, EZProxy configuration and Open Journal System (OJS) administration and debugging.
I have a further interest in machine learning, and completed my masterβs degree on the topic of sentiment analysis.
