Jozef Jarosciak

Welcome to my digital corner! I’m Jozef Jarosciak, a Slovak-Canadian living in Ontario, Canada, since the pre-Y2K era. Initially, this blog was my digital sticky note – a singular place to corral my thoughts. However, as fate would have it, this personal repository morphed into a knowledge-sharing place.

A little about my work: I navigate the complex world of business and technology architecture as an Enterprise Architect for Canada’s largest private mortgage insurance provider. My days are filled with strategizing on enterprise architecture, ensuring governance, and compliance, but also assuring design integrity, solid technology choices and many other things. It’s like being a city planner, but for digital landscapes. While, day-to-day, I wear the architect’s hat, the beauty (and chaos) of my job means I occasionally also play other technical roles. So my job description might as well read: “Jack of all trades”.

My academic journey took me to the University of Liverpool in England, where I completed a Master’s Degree (with honours) focused on IT Project Management, Information Security Engineering, Managing Organizational Resources, Cloud Computing, Web Sciences and Big Data. I am a big fan of lifelong learning and professional growth and collected several IT certifications—TOGAF, Microsoft Certified IT Professional (MCITP), and Microsoft Certified Solution Associate (MCSA), to name a few.

When not architecting the digital future, I indulge in peeling back the layers of complex architectural challenges, coding, and embarking on projects that pique my curiosity.

So, there you have it—my professional life, unpacked.

Here are a couple of my leisure projects:

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

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


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 Python Application to Convert photos on disk to Excel Travel Log and Google Map of All Visited Places

Over the past 20+ years, my family took tens of thousands of photos while visiting countries all around the world. As the years went by, the total number of stored images seems to grow every time we travel and even though we organize our images, sometimes it’s hard to recall when (exactly which year and month) we visited a specific place. Thinking about it, I realized that nowadays most photos are captured on smartphones or digital cameras that come equipped with GPS and automatically geotag each photo with GPS coordinates, as well as the date and time of each image capture.

That said, I wrote a Python GUI App (<300 lines of code) that you can point to a directory where your photos are stored and the script will do the rest. It’ll scan and extract the Exif information from all your images and convert the gathered EXIF information into:

  • Excel Travel Log – List of locations sorted by month/year

  • Google Map – This is a visual representation of all our travels. Google Map pins show the detailed date and time of our visit

Following are some screenshots from the PythonPhoto2Location app, outlining the four steps it takes to get from a collection of photos to an Excel file and Google Maps:

r/Python - Just made a Python app to convert thousands of my photos to a travel log of all places I ever visited (in Google Maps and MS Excel format)

Here is a 2-minute long Video outlining the app functionality:

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 calculate 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
