Rockstar🎓
Top SchoolJoe Lauer is a serial founder and engineering leader with 15+ years of hands-on experience building high-performance teams and scalable systems across mobile, payments, financial, and big data domains. He founded and exited multiple companies—including Simplewire (acquired 2006), Cloudhopper (acquired by Twitter 2010), and Greenback (acquired by Dext 2021)—and led Twitter’s mobile engineering team that delivered a uniquely reliable, globally distributed notification platform. Comfortable toggling between CEO duties and deep engineering work, Joe contributes to open-source Java projects (notably SMPP, a Java template engine, and JCEF integrations) and has a knack for operationalizing mission-critical systems with zero-downtime pedigrees. Based in Michigan, he combines product intuition with low-level technical chops—illustrated by contributions that span backend protocol stability, template compilation, and browser-embedded PDF printing.
