Len has been programming for over 30 years, having first started with a Sinclair ZX-80. Now he runs his own consulting company, JetByte Limited and has a technical blog here.

JetByte provides contract programming and consultancy services. We can provide experience in COM, Corba, C++, Windows NT and UNIX. Our speciality is the design and implementation of systems but we are happy to work with you throughout the entire project life-cycle. We are happy to quote for fixed price work, or, if required, can work for an hourly rate.

We are based in London, England, but, thanks to the Internet, we can work 'virtually' anywhere...

Please note that many of the articles here may have updated code available on Len's blog and that the IOCP socket server framework is also available in a licensed, much improved and fully supported version, see here for details.
