An Elderly Software Developer’s Long Journey through Technology
summary
Career summary hits specifics: forty years of development, building a dynamic BBC site when under 1,000 websites existed, writing spreadsheet libraries (PHPExcel and PHPSpreadsheet) that log 50 million downloads now 114 million, contributing bytes to PHP core (SPL doubly linked lists) and shipping many rejected patches. Practical tools are libraries and unit tests; surprising numbers and concrete projects prove impact. Core lessons are concrete too: never stop learning, preserve work–life balance, avoid gatekeeping and consider ethical abuse cases.
