Mayor Martin J. Walsh on Saturday named Gina Fiandaca commissioner of the city’s transportation department. Fiandaca, of East Boston, who previously worked as director of the Office of the Parking Clerk, had been serving as the interim deputy transportation commissioner since May 2014.

“Gina Fiandaca has served the residents of Boston for over 25 years, and brings extensive experience to her new role as Commissioner of the Boston Transportation Department,” Walsh said in a statement. “She has proven herself to be an exceptional leader, who has strong working relationships with advocates, community members, and state and federal transportation partners.”

Fiandaca, who has worked in the transportation department since 1990, has helped implement the city’s Web-based system for paying parking tickets, and the ParkBoston app, which allows users to pay parking meters from their smartphones, the statement said.
