2010 Co-founded an IT Services Company in Paris/Beijing.
2017 Led a Transformation Plan for SwitchUp in Berlin.Dec. 2024 Eager to Build the Next Milestone Together with You.
Throughout my 25-year career, I've mastered the art of leading through the intricacies of technology and management, accumulating vast experience in strategic planning and hands-on technical development. Unlike the traditional high-level strategizing typical of CTO roles, my passion lies in immersing myself within the technical trenches, working alongside talented teams to design and execute cutting-edge solutions.I am eager to apply this blend of strategic leadership and technical expertise, aiming to drive innovation, enhance team capabilities, and lead projects that push the boundaries of what's possible in technology.This approach is more than just management; it's about staying intimately connected with the pulse of technology and nurturing a creative, hands-on environment that turns ambitious ideas into reality.
Skills
Strategic Thinking
My background in basic physics has been crucial in developing my analytical skills. In my role at SwitchUp, I led a significant transformation plan that demanded a creative approach. This involved juggling short-term operational needs while steadily steering towards a completely new architecture, all achieved within the confines of limited resources.
Technical Expertise
In my view, technology serves a role that extends beyond merely supporting business functions; it is a fundamental driver of business expansion and innovation. Possessing a profound, hands-on understanding of technological capabilities is key to creativity.
Reliability
I am deeply committed to my clients and their projects, delivering quality work with keen attention to detail. Maintaining transparent communication, I build trust-based relationships. My dedication ensures I am a dependable resource, even in challenging situations.
Cross-Cultural Management Expertise
My career has largely unfolded in diverse, multicultural settings. In the 1990s, I facilitated the entry of French companies into the Chinese market. The 2010s saw me establishing a company in China, and more recently, I've collaborated with a Berlin-based startup, working alongside a team of Russian developers. On a personal note, I'm now settled in Portugal.
Metrics
Team size
For my own company, Second Bureau, I successfully hired and directly managed 17 individuals in Beijing. Remarkably, over a three-year span, only one person chose to leave the team. Considering the average turnover rate in China at the time was six months, this achievement is something I take great pride in.
Going back to 2007 with Generali, I directly oversaw a tight-knit group of 12, comprising both internal employees and outsourced professionals. Additionally, I held broader responsibility for approximately 30 team members.
Industries & Markets
Energy / German Market
For more than 6 years, I led a transformation plan for SwitchUp targeting a significant overhaul of the energy market in Germany. This involved in-depth analysis and understanding of the unique dynamics of the German energy sector, adapting innovative technologies to meet the market's specific needs, and navigating regulatory frameworks.
China
My connection with China began in the late 90s and has been enduring. Initially, I was employed by the French Chamber of Commerce, where I assisted French companies in setting up their operations. Additionally, I co-founded a ready-to-wear fashion brand, with production rooted in China.
Bank and Insurance
In the early 2000s, I held various roles at BNP Paribas, Crédit Agricole, Generali, and Natixis, specializing in business intelligence and performance management. My tenure in these organizations focused on enhancing data-driven strategies and operational efficiencies, particularly in the IARD sector. This period was instrumental in shaping my understanding and expertise in the banking and insurance industries.
Real Estate
My involvement in real estate is driven by a profound personal interest. I oversee a family-owned enterprise that holds 8 properties. While I don't claim to be an industry expert, my experience has equipped me with a solid understanding of the market dynamics and economic aspects of it.
