Senior Technologist | Python, Linux, Data Engineering | Calm, Reliable, Long-Term Builder
I’m a senior technologist with 20+ years of hands-on experience in software development, data engineering, and applied machine learning - across sectors like pharma, finance, logistics, and research. My core tools are Python, Linux, C, and the open-source ecosystem. I’ve built and maintained data pipelines, machine learning workflows, and complex backend systems - always with a focus on clarity, maintainability, and real-world value. I’m most at home in roles where technical depth, calm collaboration, and long-term thinking matter more than hype. I prefer environments where people care about how things are built - not just how fast. I’ve also taught and mentored in Python, Linux, and Deep Learning, and contributed to open-source projects for many years. Currently looking for part-time roles in data engineering, scientific computing, or backend systems - especially within mission-driven organizations, research institutions, or smaller companies that value substance over buzzwords. If that sounds like your world, let’s get in touch.

Cultural Fit Analysis
The candidate's diverse experience across different company sizes and industries (patent law, consulting, financial sector, IT automation) suggests adaptability. Their involvement in open-source projects and focus on local AI systems with strong privacy requirements indicates an interest in impactful and ethical technology, which could be a strong cultural fit depending on the company's values. However, the target role is ML Engineer, and while their experience is relevant, the recent part-time system admin role might indicate a slight deviation from a pure ML focus, potentially impacting cultural fit for a highly specialized ML team.
Soft Skills & Operational Fit
The candidate's experience as a consultant and in collaborating with legal teams suggests good communication and problem-solving skills. Their involvement in open-source projects indicates a proactive and collaborative work attitude. The role as System Administrator also points to operational awareness and responsibility.
