Shumil - very sharp and exact technichal and logical descriptions. No contradictions and baby-talk in technics (especially computer technics) if you know what I mean. Though some major fails in psychology and ethics IMHO. The main character usually is too masculine...Though female characters around are able to make fun of him even if unable to resist his charisma.
Scheglov - his Panga series is an example of sci-fi\fantazy mixture - very natural. The idea of magic describes a perfect user interface of a powerful high-tech device, doesn't it?
Rudazov - easy reading. Travels between worlds and adventures. Particularly good in comedy situations and charachters' banters. Start with Archmage series from the beginning. Later it goes worse.
Lazarchuk - «Иное небо» - an alternative history. Intellectual and rather complicated... Actually can't recommend reading in foreign language. But it is in my short list.
Max Frei - a woman actually. No SF though. "Labyrinths of Echo" series is a Harry Potter for grown ups with a very specific view of life and philosophy, which you either adore of hate.
Kamsha - two epic sagas in fictional medieval-to-renaissance-like worlds with mystics, magic and intensive eschatology. No one is completed up to now. No problems with credible female charachters as she's a woman. She's a fan of GRR Martin and her sagas resemble his one but they are way not so cruel and way more romantic.
Bushkov - mainly known for his action but has a nice series of SF\fantasy "Svarog". A lucky idiot in a Boschian world. First three novels are readable then he sold his name to publishers and now they publish garbage by shadowwriters in that series.
