Senior🎓
Top SchoolJosef Novotný is a data scientist with 12 years of engineering experience, currently building ML-driven fraud and AML detection systems at Česká spořitelna in Prague. He combines strong software engineering roots—from embedded systems and aviation prototyping to backend development—with expertise in data processing, predictive modeling, deep learning and computer vision. His work includes hands-on ML productionization and a rotation at Erste headquarters, reflecting both domain depth in finance and cross-border collaboration. An active contributor to open-source tooling, he implemented core ASN.1 type support and extensive test automation in the pycrate Python library, demonstrating a focus on robust encoding/decoding and quality assurance. Practical, curious and systems-minded, he bridges low-level protocol engineering and high-level ML solutions to deliver reliable, auditable data products.

Contributions summary:Josef primarily contributed to the `pycrate/pycrate` repository by implementing support for various ASN.1 basic types, including Null, Bool, Integer, Real, Enumerated, Object Identifier, BitString, OctetString, and String types, along with their corresponding _ws methods. These _ws methods likely indicate a focus on efficient encoding and decoding routines. Additionally, the commits include significant test suite updates within `test/test_asn1rt.py`, demonstrating a strong emphasis on automated testing to validate the correctness of the implemented ASN.1 type support, highlighting a quality assurance focus.
