*Between the hardware and the micrcontroller layer?

A Description of My Job

As a software engineer, I work on near field communication (NFC) applications, which are rooted in radio-frequency Identification (RFID) technology. The purpose of these applications is to allow, though the use of radio waves, compatible hardware to both supply power for and communicate with, an otherwise powerless and passive electronic tag. They are typically in use in contact and contactless payment systems for identification, authentication, and tracking purposes. My job is to maintain the C++ library and to add new features on it. The processes within the library enable the communication to happen between the hardware, the microcontroller layer (or “readers”) in RFID/NFC cards, and the application layer within the computer.*

Hi, Tien. Good job! While this field is way out of my league, whatever changes I made were to allow your sentences to sound more natural to native ears, to clarify your thoughts, and for ease of reading. Sincerest apologies if I have misinterpreted. I hope that this helps you. J.

*You used “libraries” in your original, then referred to them as “it,” but in the next sentence, you referred to “This library…”  This is confusing for the reader. Regardless of which form you use (plural or singular), be consistent throughout your text.

(As an aside, it seems the spelling for term "near field communications" is all over the place in terms of its construction (all capitalized first letter, hyphenated, etc.), and seemingly up to the source. Given that it is a somewhat new technological term, it is not surprising that a standard, in terms of formating, has not caught up with it. Thus, no one can truly say "it should only be written this way."  My best advice, for now,  is to refer to it in your writing as it is done in the industry...)
