The commanding Frenchman was one of the Wings' stand out performers last season but he's announced his departure.
Since their play-off final defeat in May there have been sweeping changes at Park View Road including a managerial switch.
The 32-year-old took to social media to announce his decision to take up a new challenge with Brackley Town.
"I want to say Thank you very much to Welling United for the great moments spent in 2018/2019," he wrote on Instagram.
"Fans also been massive. It's time for a New challenge now... @brackleytownfc."
