My name is Jozef Jarosciak and I am a Slovak Canadian living in Ontario, Canada. This blog started as a notepad for myself (to find my notes in one place) but eventually also became a spot to share my knowledge.
I work as a Systems Architect for a large IT company in downtown Toronto, Canada. My primary focus is on Infrastructure Architecture, IT Strategy, DevOps, Professional Services and Software as a Service (SaaS).
I have completed a Master’s Degree focused on Web Sciences and Big Data with honours from the University of Liverpool in England and hold several well-known IT certifications, such as TOGAF, Microsoft Certified IT Professional (MCITP) or Microsoft Certified Solution Associate (MCSA); and I am also certified for various methodologies and/or technologies such as ITIL, Project Management or Agile Development & Methodology. More on LinkedIn.
My daily routine consists primarily of being a systems architect, but often those lines get blurry in my line of work and I often find myself working as a software designer/developer, infrastructure administrator, DBA, app deployment manager, installer, patcher, fixer, debugger, estimator and pretty much everything in between.
In my spare time, I love to learn about complex architectural issues, but also engage in coding and work on various interesting projects.
Some of my more recent spare time projects are:
- UsenetArchives.com – This is one of my more recent 2020-21 projects, serving as an attempt to restore the Usenet text archives into web searchable form. The site was featured in the Vice magazine and it is currently one of the most extensive archives of Usenet newsgroups on the Internet, archiving hundreds of millions of Usenet posts from early internet days (1984 until now). Free-of-charge access is possible via the web interface, without a requirement for a third-party Newsreader
- Text Entry Assistive Cloud-Based Platform – The primary goal of this Open Source prototype was to create a web-based real-time text analysis engine, which based on inspection of the entered text offers predictive suggestions to the end-user. The project wants to show that smart predictive technologies can speed up the process of creative writing as well as improve user experience and overall user productivity.

- Canadian Mortgage Calculator (Angular & Typescript) – This is an open-source Canadian mortgage calculator that takes into account that loan interest in Canada is compounded semi-annually, rather than monthly as it is in the USA. Also online at: Mortgage Calculator
Other small projects:
- AWS Lightsail Backup and Clean Up Script – Open Source script to automatically backup an Amazon AWS Lightsail snapshot and then remove old AWS Lightsail snapshots.
- DuckDNS Client – DuckDns Updater is a Windows tray application that allows you to keep your dynamic hostname’s IP address up-to-date (and in sync) with DuckDns DNS service at www.DuckDns.org
- and many more…
You can find me on Twitter and if you wish to speak to me, don’t hesitate to connect with me on LinkedIn. I am a big believer in open source, and most of my work can be found as open-source releases on GitHub.
