Summary
👤
SeniorWolfram Rittmeyer is a senior Android developer based in Münster with 13+ years of software engineering experience, blending deep Android API expertise with a strong Java/Java EE background. He runs OpenMinds UG, helping clients build cleanly architected Android apps, and has a long history of enterprise Java work in banking and web platforms. A prolific speaker and blogger (Grokking Android), he regularly presents at international conferences on topics from ConstraintLayout and RxJava to Android Things, Kotlin DSLs, coroutines and Jetpack Compose. His practical focus is on testable, maintainable mobile architectures and voice/IoT integrations, reflecting hands-on experience extending the Google Assistant and Android Things projects. Certified in SCJP, SCWCD and LPI Level 1, he combines server-side knowledge (GlassFish, Tomcat, EJB, JPA) with mobile-first design. Less obvious: he pairs public speaking with long-term community teaching through tutorials and magazine articles, making him as comfortable mentoring teams as shipping production apps.
