Born in Moscow in 1938, Skvortsova studied architecture at the Central Asian Polytechnic Institute in Tashkent in 1955-1961. There, she married her fellow-student, Yuri Tumanian (1938-1997), born in Tashkent to a Jewish-Armenian family. Upon graduating, the couple moved to Almaty, Kazakhstan, where, working in several design institutions, Skvortsova moved from architect to head architect of projects: between 1961 and 1975, Skvortsova designed 20 buildings in the Soviet capital of Kazakhstan. 

In 1975, Tumanian was appointed the head architect of the newly-founded Chişinăugorproekt institute, and the family moved to Moldova, where Skvortsova became a head architect of projects. Between 1975 and 1990, Skvortsova designed eight projects in Chişinău, the most celebrated among which is the City Gates complex, designed with Arkady Markovich and Anatoly Spasov in 1977-1980. The two sail-shaped high-rise residential blocks of the complex flank the Peace (Dacia) Avenue in Chişinău, marking the entrance to the city. The buildings, whose height varies between 12 and 24 stories, became one of Chişinău’s most recognizable symbols. 

In 1991, after the collapse of the Soviet Union, Tumanian was able to secure a position of the head of the local Giprogor institute in Stary Oskol in the south-west of Russia, where Skvortsova became a head architect of projects. She remained in Stary Oskol for the remainder of her career, becoming the director and later head architect of local planning company Grado in the 2000s.
