Tyler Duzan

Tyler Duzan is a 10+ year veteran of the tech industry. He got his start with computers at a very young age, learning his first programming language (BASIC) at six years old. As he got older his fascination with computers progressed into a passion for all things technology with an emphasis on security. As part of exploring this passion he has learned a broad range of technical skills including a deep understanding of Windows, Linux, and networking. Most recently, Tyler has begun applying his methodical data-driven approach to decision making and strategic focus to business problems instead of technical problems in his role as a Product Manager at Percona.
My top 10 Gallup Strengths are Arranger, Responsibility, Learner, Ideation, Activator, Command, Achiever, Intellection, Input, Communication. My Myers-Briggs is INTJ. I specialize in problem-solving, absorbing and understanding complex systems, explaining these systems in a simple manner, and producing excellent documentation. During my career I've architected, implemented, deployed, and operated everything from a collection of small but business-critical applications to the second largest public Cloud in the world. I also have demonstrated success at reaching compliance goals and building things with security in mind. My skill-set crosses business and technical boundaries, allowing me to solve almost any problem with aplomb.
