I work as a junior graphics engineer for an Android OEM. And I have worked on their in-house custom mobile AR rendering engine, which was later canceled infavor of an AOSP related project where everything is under NDA.
So even though I have worked here for 2.5 years. And have decent computer Graphics knowledge, I'm finding it hard to explain what I have done.
Edit: my total experience is 3 yrs, so my current job is the only significant experience that I have.
