Trained as an electrical engineer and computer programmer. Spent 25 years in business software development creating financial tracking and reporting systems, with a focus on data transformation and multi-dimensional analysis tools. Currently, I run a small manufacturing company producing customer polycarbonate enclosures, and making replacement parts to keep older 3D printers working. With a lifetime of electronics tinkering and a wealth of repair experience - everything from restoring 100 year old sewing machines to reviving an 18 year old electric motorcycle, As part of giving back to the community, I've helped thousands of owners keep their older sewing machines functional and out of the waste stream, by providing the key information they need to fix and operate their machines. Turning a hobby into a business providing thousands of manuals for hundreds of older machines, which are no longer support by the original manufacturers.
