Welcome to Tin Lion Software Limited, an independent software development house providing contract services.
I’m your host, proprietor and sole employee, Martin McCallion. I’d like to introduce you to the services I offer.
A programmer with almost thirty years of experience, I specialise in Java, but have expertise in several other languages and knowledge of several more.
Most of my experience has been in financial software, in particular payments systems. But I can work in other areas, and am always keen to expand my knowledge.
