✨ The Eras of WordPress Evolution

  • 2003–2004: The Birth (Fork of b2/cafelog): Started as a solution for a stalled project by Matt Mullenweg and Mike Little, focusing on typography and ease of use.
  • 2005–2010: The Plugin & Theme Era: The introduction of plugins (1.2), themes (1.5), and the dashboard (2.0) turned it into a flexible platform rather than just a blog.
  • 2011–2017: The CMS & Mobile Era: Focus on custom post types, multisite capabilities, responsive admin interfaces, and the REST API made it a true CMS.
  • 2018–Present: The Gutenberg/Block Era: The shift from a classic editor to the block editor (Gutenberg) in version 5.0 (2018) revolutionized content creation toward “what you see is what you get” (WYSIWYG) site building.

Welcome to my site! After graduating in Computing in 1990, I accepted a position as a programmer at a Runcorn based software house specialising in electronic banking software, namely sp/ARCHITECT-BANK on Tandem Computers (now HPE NonStop). This was before the internet became more prevalent and so the notion of enabling desktop access to company accounts for inter-account transfers and book keeping was still quite a cutting edge idea (and smartphones only ever hinted at in Space 1999). The company was called The Software Partnership (which was taken over by Deluxe Data in 1994). I spent 5 years in Runcorn developing code for SP/ARCHITECT for various banks like TSB, Bank of Scotland, Rabobank and Girofon (Denmark) to name but a few. I then moved onto a software house in Salford Quays for further bank facing projects. After a further 23 years in the IT industry and now a Senior IT Project Manager (both Agile and Waterfall delivery), I thought I would echo out my Career Profile in this corner of the internet for quick and easy access.
