Technical QA Manager based in Florianópolis, Brazil. I have 20+ years in software quality, working with US and global teams at Xerox, Dell, HP, HPE and CESAR.
By day I lead QA teams and test strategy. In my spare time I reverse-engineer, document and emulate vintage computers. White-box testing with a soldering iron.
