Saarland, Germany
Summary
🤩
Rockstar🎓
Top SchoolPatrick Steuer is a results-driven Vertriebsgebietsleiter based in Saarland with 10 years of professional experience bridging technical service, business development and regional sales in industrial filtration. Trained as a staatlich geprüfter Elektrotechniker and formerly an avionics technician in the Bundeswehr, he combines hands-on electrical and avionics troubleshooting with commercial acumen for the Food & Beverage and air filtration sectors. At Freudenberg Filtration Technologies he progressed from service technician to business development and now leads regional sales, pairing technical consulting with revenue growth. Unusually for a sales leader, he also contributes to low-level cryptographic code on the widely used OpenSSL project, optimizing s390x-specific crypto primitives—evidence of deep systems-level understanding and attention to performance. His blend of field service experience, technical qualification and open-source engineering gives him a practical, credibility-driven approach to customer solutions and product improvement.

Contributions summary:Patrick's contributions focused on implementing and optimizing low-level aspects of the OpenSSL cryptographic library, primarily concerning the s390x architecture. The commits include the integration of processor-specific instructions (PCC, KDSA, KMA, KMAC, KMO) to accelerate fundamental cryptographic operations such as AES, ChaCha20, and ECC scalar multiplication and signature verification. Further improvements involve fixing performance regressions and addressing build issues for strict ISO C90 builds.
