I am a retired software engineer with 43 years experience. I was first employed by a software house in 1967. I was paid £15 a week an immediately put out on contract for £100 a week, writing device drivers and system software in machine code on a small office computer. I worked on this type of computer for several years writing in machine code and updating the micro-code that ran the computer, I then wrote a cross-compiler to generate the machine code. I then worked on compilers and cross-compilers for mini computers and main frames. I then moved on to developing real-time systems working in assembler on message switching and communications systems. I worked on System-X, one of the first packet switching systems on which the internet is now based. I worked on the SpaceLab ground check out operating system amongst other high profile projects. I was a founder member and director of a small co-op software house and also ran my own company and wrote and published my own software. In later years I worked for a small engineering company to develop the software for engine and vehicle testing. When the software was moved to Windows I had to rewrite all the real-time aspects of the software as a device driver to minimize the latency. I have worked on smallest embedded micro processor systems to the largest main-frame systems, mainly working in Assemble, C and a host of high level languages. I retired in 2010. I have little experience in smartphone technology as the smartphones I have had so far, I have always kept offline as I hate being tracked, Now with my /e/ phone I can at last have a smartphone I can trust not to track me. So thank you all so much for all the hard work you have put into the e-project.
