Italo Souza, 22, filmed a 28-second video as he pointed his phone upward while standing behind a woman on an escalator at the shopping centre in Shepherd’s Bush.
Ten days later, he exposed himself to three lone women as he rode around West Hampstead on his moped just after 1pm.
As a self-employed Deliveroo driver, he had accepted jobs dropping off items from Pasta Evangelists and Co-op between the flashing incidents.
That same day he filmed a further two women under their clothing at a KFC fast-food restaurant in Edgeware Road and at Mooboo Bubble Tea in Camden.
On Wednesday at Wood Green Crown Court, Souza was sentenced to an 18-month community order with 100 hours of unpaid work to be completed and a 30-day rehabilitation activity requirement.
He had previously pleaded guilty to three counts of exposure and three counts of voyeurism.
Gillian Travers, from the CPS, said: “Italo Souza exposed himself to three lone women in broad daylight making them feel vulnerable, scared and uncomfortable.
“One victim described seeing Souza holding his camera phone in one hand while exposing himself and smirking at her, adding to her distress. He also filmed three different women under their clothing without their consent in public places, including at a KFC and below an ascending escalator in Westfield shopping centre.
“This is illegal and a grave invasion of privacy.”
The prosecution case included strong witness testimony from three victims and CCTV footage of Souza riding around north London on his moped wearing distinctive orange shorts, Ms Travers said.
“Women should be free to go about their lives without having their privacy invaded in this vile way or being sexually intimidated. It is important that those who behave in this way know they will be prosecuted,” she added.
“Exposure and voyeurism may indicate a propensity to commit more serious sexual offences. We as the CPS want women to know they can be confident we are robust in stopping these perpetrators in their tracks.”
