Hello, does anyone know how to recruite Deborah 'Dobby' Carter, I'm 90% and says "contact your district contact, and I do not appear on the map and I walked all anyone knows any solution or is it a bug?
No, you're missing something because she's not visible on the map. This happened to me too. I completed the North District liberation missions and Dobby still didn't show up. After riding my horse all through North District, I realized that I still needed to help some orphans distract some vendors and help some farmers protect their crops. The map didn't show me these missions so I think it was glitched. After helping them, Dobby finally showed up. You can go to her location now but she won't talk to you unless you complete all your tasks in North District. She's located in the North-West corner of the map. She's standing by the house with the green door.

Once the map shows the Templar control at 90% you should get the mission to speak with Dobby. Then you have to go to the North-West most point of the map and search around until the Mission Marker shows up.
