Profile bio

About Denis Walraven

I am an energetic and versatile project manager with broad technical insight, international experience and solid experience in aligning technology with business processes and working as a managing contractor in multidisciplinary technical projects. I have a proven track-record in getting projects (back) under control and improving projects / results by enhancing team performance (and atmosphere), improving processes and improving stakeholder management. My aim is to keep developing as a senior project manager, tender manager or program manager, working with state-of-the-art technology in the field where technology aids the environment, the business or where it meets the (sea) water. I feel at home in challenging projects that have not been done before, whether it being pilot projects or projects where new technology is implemented. My ultimate ambition is to leave the environment just a little bit better and more green than when I started. Joining a team where this can be achieved is a factor that weighs in for next steps, preferably in the energy sector or in the field of sustainability.

Listed skills include Project Management, Process Improvement, Change Management, Operations Management, and 17 others.
