Checking a box here.
I have done thousands of wireframes. I typically start with a hand sketch (or whiteboard sketch) and with each iteration move the UI toward a higher level of fidelity. I don't do a lot of "pixel perfect" work anymore but I do a lot of rapid prototyping for purposes of concept testing, A/B testing, MVP development, and user testing.
The below wireframe was done in Figma. I am also proficient in Adobe Illustrator, Sketch and Adobe XD.
