SUMMARY As a software engineering leader with 21+ years of experience in the industry, I have three main themes of work that I focus on in all my roles in software development:

  • Discovering and attracting great talent and bringing out the best in people by providing them support through my Servant Leadership management style. I strongly believe in doing everything I can to support team members professionally and personally through the use of regular honest and constructive 360 degrees feedback and through coaching and mentoring.
  • Developing teams to be great at software development by correctly adopting Agile Development, Lean Startup Principles, and the best industry standards and practices. I love to help make the organization's SDLC (Software Development Life Cycle) fun, engaging, efficient, safe, and secure through the use of Continuous Integration, Continuous Delivery, and the right set of tooling and technology.
  • Helping to improve how Engineering works with leadership, sales, product, and even customers. I strive to find ways to break down barriers, clarify miscommunications, and define processes and practices that help improve and streamline constructive interactions.
