Freelance Problem solving Developer - Bogdan Branescu
Freelance Problem solving Developer

Getting things done while everyone is evolving professionally is what I call a win-win situation. I deliver a high level of performance and demand that from my teams. I thrive in an environment where I have to make decisions and deliver results. Having a higher emotional intelligence I find it easy to collaborate and communicate. I take the lead and build inter team competence by demanding respect and trust. These standards are non-negotiable for me. I work smart and provide reliable management so I will let you know if something is unrealistic, not based on data or simply not right. I do my best work in managing expectations, especially in crises. Going back in time in my over 15 years of experience I am truly grateful for the generous portfolio of successfully delivered projects that enlarged my IT landscape knowledge base. Starting with navigation software, going through media, smart home, financial services and even air transport, I can now say that I am at a real level of seniority in terms of IT management. If you have your own IT team or product and you demand high standards, please do contact me.
