Summary
👤
Senior🎓
Top SchoolJoel Rudsberg is a software engineer at GraalVM with eight years of hands-on experience building high-quality, user-focused software across startups and research-driven teams. An EPFL MSc graduate, he turned a master’s thesis on compiler fuzzing into infrastructure that uncovered 25 previously unknown Graal performance bugs and measurable regressions versus C2. As co-founder and lead developer of AR startup InnoTact he shipped multiple iOS apps (one with 100k+ users) and learned product, sales, and UX iteration at scale. He combines low-level performance debugging and JVM expertise with polished iOS and full‑stack development skills, thriving in fast-paced, boundary-pushing environments. Based in Zürich, he brings an entrepreneurial mindset and a proven track record of turning experimental ideas into production-grade software.
