Fyrabarns-far, farfar, morfar och egen företagare i Skellefteå med kliande fingrar. Jag skriver om fotografering, sport, dataprylar, politik, nöje, musik och film. Vid sidan av den här bloggen så jobbar jag med med det egna företaget Winterkvist.com. Familjen består av hustru, fyra barn (utflugna) och fem barnbarn.

Jag har hållit på med datorer sedan tidigt 1980-tal och drev Artic BBS innan Internet knappt existerade. Efter BBS-tiden har det blivit hemsidor, design, digitala medier och trycksaker. Under tiden som journalist jobbade jag med Mac men privat har det varit Windows som har gällt fram till vintern 2007. Då var det dags att byta och då bytte vi, företaget, helt produktionsplattform till macOS. På den vägen är det.
