PROFILE

  • With over 15 years of experience as an IT manager and executive, I have a proven track record of building and leading successful teams. As a pragmatic thinker with a keen eye for detail, I am driven by a passion for delivering results. While I focus on the finer aspects, I always maintain a big-picture perspective, ensuring a comprehensive understanding of processes and progress. I am adept at translating my visions and ideas into practical solutions, leveraging existing standards, agile methodologies, and iterative development approaches to achieve tangible outcomes.
  • Throughout my career, I have worked extensively on critical and high-performance systems, managing and optimizing large volumes of data. These experiences have equipped me with invaluable expertise in handling complex data environments. In my role as a technical and managerial leader, I have spearheaded the development of such systems, taking a pivotal position in their planning and execution.
  • Having held central roles as a CTO and team lead in small and medium-sized companies, I have honed my communication skills through continuous collaboration with internal departments and external partners on an international scale. Whether engaging in negotiations, project planning, or conceptualization, I have consistently been recognized for my ability to effectively communicate complex technical concepts to non-technical stakeholders. My colleagues and team members have consistently valued my broad professional knowledge, which has proven instrumental in successful project implementation.
  • In summary, my extensive experience as an IT manager and executive, combined with my meticulous attention to detail, strategic thinking, and strong communication skills, uniquely position me to drive meaningful outcomes for non-technical management teams.
