The Crafty Mage: Frontier Settling Made Easy

Joshua worked as a crafting wizard as part of an exploitative order of chivalry that gave him no vacation time and a pathetically low monthly salary. His childhood friend heads the order, but has long forgotten the ideals and purpose on which it was founded: to fight the Demon King's army in order to help the people. So Joshua broke off all ties with him, left the order, and departed on a journey to find a new job. While travelling, he ends up rescuing Iria, the daughter of a tribe of half-human, half-ogres who are on the run from a group hunting demi-humans. As thanks for saving her, Joshua is warmly welcomed into the village of the ogre-humans... But there, he sees how they are being oppressed by both the Demon King's army and slave traders, and he decides to use his crafting magic to help them?! Source: Square Enix
