Solutions Engineer, Software Engineer, Cybersecurity Professional, Open Source Enthusiast
📌 Software leader with 28 years of experience across software engineering, project management, cybersecurity, and pre-sales. For 15 years, I built and led my own software development company across Germany, Hong Kong, China, and the US. That experience gave me the ability to navigate the different business cultures and communication styles required to deliver complex projects across three continents. 🇩🇪 🇭🇰 🇨🇳 🇺🇸 💻 As a Principal Application Security Consultant, I specialize in securing custom software applications across the entire stack. My approach centers on a robust DevSecOps philosophy, embedding security directly into the engineering lifecycle to ensure resilience without sacrificing velocity. Beyond traditional vulnerabilities, I help organizations navigate the modern attack surface by securing AI and LLM implementations against emerging threats. By applying frameworks like the OWASP Top 10 for LLMs alongside deep-dive threat modeling and pipeline automation, I ensure that innovation and security move at the same pace, while maintaining alignment with key regulatory mandates such as CRA, NIS2, DORA, and the EU AI Act.

Cultural Fit Analysis
The candidate's project portfolio shows a strong inclination towards personal, open-source contributions across a wide array of technologies (JavaScript, Java, Python, Ruby, Swift). This indicates a self-starter mentality and a passion for learning and building. However, the projects are highly diverse and not deeply focused on iOS development, which is the target role. The current employment as 'iOS Developer' at 'sonarsource' is listed with a future start date, implying no current professional experience in the role. The breadth of certifications, while impressive, also suggests a wide range of interests rather than a deep specialization, which might impact cultural fit for a highly specialized role.
Soft Skills & Operational Fit
The candidate's extensive list of certifications, while diverse, does not directly provide insight into soft skills or operational fit in a team environment. Certifications like 'Certified ScrumMaster (CSM)' and 'Certified Scrum Professional (CSP)' suggest an understanding of agile methodologies, which is beneficial for operational fit. However, without actual work experience descriptions, it's difficult to assess practical application.
