November 2021
For this particular project, I had to go through various compliance measures to make sure my work followed stringent industry standards. This was completed on time and within budget. It’s a great example of my dedication to deliver a quality product and see it through from start to finish despite complications in order to ensure full client satisfaction.

While working on this project, I was very strict about the materials and footprint of my work.
