Rockstar🎓
Top SchoolAlexander Schrode is a software developer with 13 years of experience who blends applied data science and systems programming expertise, currently working at Inworks GmbH after a data science trajectory at SV SparkassenVersicherung. Trained in mathematical economics (MSc/BS Wirtschaftsmathematik, Universität Ulm), he has hands-on experience in insurance, e-mobility analytics, and actuarial internships, bridging quantitative modelling with production software. An active open-source contributor to OPC UA implementations in Rust and Python, he has improved core protocol correctness—fixing GUIDs, OptionSets, secure channel padding and null-array decoding—showing deep protocol-level understanding rather than only application code. Based in Ehingen (Donau), Germany, he brings both rigorous numerical thinking and low-level backend craftsmanship to projects that require correctness, security, and reliability.
