Summary
👤
Senior🎓
Top SchoolAxel Wagner is a software engineer with a strong foundation in distributed systems and 16 years of engineering experience, currently building trading or finance-related software at Infront Quant AG from Heidelberg. He spent three years as an SRE at Google ensuring scalability and reliability for services like Gmail and Google Calendar, and most recently worked on next-generation production automation across Google. Axel combines hands-on backend systems work with operational responsibility—oncall, design reviews, monitoring and automation—bringing practical DevOps discipline to large-scale services. He is an active open-source contributor with notable backend contributions to high-profile projects such as golang/crypto (improving OpenPGP signer behavior and hash support) and the i3 window manager (fullscreen and IPC improvements). Trained with an MS in Mathematics and Computer Science from Heidelberg University, he blends rigorous theoretical background with pragmatic engineering. Colleagues would describe him as an engineer who moves smoothly between low-level cryptographic compatibility fixes and high-level production automation design.
