I am a programmer. I am pretty good at algorithmics. I love implementing something out of a published paper. I love to navigate the math. I can't sell that though.

I just used to say I am a computer vision expert, because in the ton of things I can do, this is a relevant domain.

Recently, advances in deep learning made half of the computer vision field obsolete. I just read some cutting edge DL papers, linked that to the things I know, and now I am a deep learning integrator.

I was taught in engineering school that my craft is learning and problems solving. I sell it as knowledge and expertise but the truth is that I am constantly learning in the domain I sell as my specialty, which is what everyone who is decent at anything actually does.
