• Bringing design concepts to life using AutoCAD and Civil 3D, while contributing to project timelines and quality standards.


• Understanding the importance of time management and project budgets and consistently delivering work in a way that supports schedule and cost expectations.


• Earning the trust of colleagues and clients through consistent, solution-oriented communication and a proactive mindset.
