Jozef Jarosciak

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:

  • – 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.

  • Open Source Bananagrams Solver in JavaScript, PHP & MySQL – This was a fun project. I had a little bit of spare time over the holidays and decided to find a programmatic solution to a game of Bananagrams and built a variety of MySQL dictionaries from Aspell, HTML and CSS were used to style the page, then coded the backend in PHP and placed a solver logic into JavaScript web worker. Here is a short outline of the entire process along with a website and a YouTube demo. Out of this project came two websites: and


  • JavaScript n-Block Tangram Puzzle Solver – Another recent fun project is to create a Block Puzzle Solver to calculates the solutions to monomino, domino, triomino, tetromino and pentomino(1) based rectangular or square tangram puzzle in a user-defined area, with support for block rotation and reflection. The fast version uses a random unique block combination. The slow version tests all possible block combinations and permutations (there can be quite a lot of them). The plan for the future is to include more pentominoes, heptominoes, octominoes & other polyominoes; as well as support user-defined areas of any shape. Available online at Block Puzzle Solver




Other small projects:

  • 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
  • and many more…
