+Hello ~TiddlyWikiers - I have been a long time fan, recent contributor to the TW community. 
+Recently I have volunteered to run the [[TiddlyWiki Newsletter|https://tiddlywiki.substack.com/]] to spread the great news about TW.
+
+I have been in the IT industry for about thirty years, mostly as a consultant and technical arcitect.
+More recently I went back to study a masters in IT focussing on AI and data science.
+Now my partner and I have started our own business ([[Sphere Innovations|https://sphere-innovations.com.au]])  - in consulting and building web applications for small to medium size businesses here in Australia.

+
+Since 2014, when I started college, I've been on a quest for a lifelong PKM tool. I cherish my life and all my experiences, and I don’t want to forget any of them. When I’m deeply focused on a task, it’s easy to lose sight of other important parts of my life—so I needed a system to help me stay balanced.
+
+Early on, I tried TiddlyWiki several times, but I was initially put off by its save mechanism and markup editing. That changed when I discovered an auto-backup script, which gave me the confidence to fully commit. Over time, I improved the script and eventually transitioned to using TidGi-Desktop and TidGi-Mobile.
+
+Today, my TiddlyWiki holds all my game design ideas and progress logs—it has truly become my second brain. With the help of LLM-powered programming tools, I’ve enhanced it with numerous plugins, allowing me to manage my mind in a more programmable and structured way. As a game developer, TiddlyWiki isn't the core of my professional work; But I've invested so much time because it's fundamentally about upgrading my mind.
+
+Most of my notes are open by default and shared publicly on my homepage as a digital garden.

+''Hi, My name is Mario Pietsch''. Back in 2009 I was ''searching'' for ''a simple presentation tool'' and discovered ~TiddlyWiki Classic, Monkey Pirate ~TiddlyWiki ([[MPTW|https://mptw.tiddlyspot.com/]]) with ~TagglyTagging, Eric Shulman's ~TiddlyTools, Saq Imtiaz's navigation macros, and more. --- ''I was captivated''.
+
+After a deep dive, I combined these elements into my own "Presentation Manager", along [[3 step by step tutorials|https://groups.google.com/g/tiddlywiki/c/qG_tZ1x0MEU/m/-vLA0luMicYJ]] to help others build it. 
+
+Thanks to ''the positive spirit'' of the ~TiddlyWiki community, I am proud to be part of it since 2009.
+
+When Jeremy started developing ~TiddlyWiki 5 on ~GitHub, I joined in—opening [[issue no. 1|https://github.com/TiddlyWiki/TiddlyWiki5/issues/1]] all the way up to 13. For what that’s good ;) Since then, I have submitted nearly 600 pull requests and more than 500 issues, many of which have been merged or resolved.
+
+My ~TiddlyWiki 5 "laboratory" is at https://wikilabs.github.io, and I also share content on my ''~YouTube'' channel: https://www.youtube.com/@pmario
+
+Have fun!<br>
