Hello, I’m Vimal. I write, teach, and speak on topics involving Linux, Python, and open source software.

Drop into my virtual office
If you would like to talk to me, you can drop into my virtual office for 10 minutes.

For over 9 years, I supported research groups in biological sciences with their computational and programming needs.

During this time, I had installed and managed Linux servers, databases, web applications, and websites, developed software as part of a team, and published packages on PyPI, Anaconda, Galaxy Tool shed, OBS and Docker hub.

I’m a Linux user for 20+ years. Feel free to get in touch with me, if you need help getting started. I organized Linux meetups in Cork (2017-2018).

I am a member of the UCC Indian Alumni Community. I write content and manage the community website.
