Josiah is a senior full-stack developer with a strong background in all things JavaScript and front end. He loves JavaScript and building applications with Laravel. He is a CSS wizard who's built a great number of web apps from scratch, worked on enterprise web front-end teams, taught others to become front-end developers, and mentored junior front-end devs. Josiah's latest project was founding a SaaS company he ran successfully for four years before being acquired (LAMP stack/AWS/Laravel/Vue).
