## 2022-09-16: Meeting-With-Jack-Blevins
We met with Jack Blevins, a UIUC alum whom has earned one of the first EECS degrees
back in 1970 and has a 50+-year track record spanning all kinds of
projects in industry (recommended to use by Professor Lumetta), and will essentially serve as another, "informal" mentor for our 445 project. Our team gave an overview of our project and followed up with some questions and comments from Jack:
- Jack essentially solidified our design decision from earlier and agreed that trying to implement and incorporate 5 GHz frequency into our Wi-Fi module would be too impractical.
- For the Web programming side of things, we discussed which applications, languages, databases, etc. we were going to utilize. Since we established that we would be using AWS for our server side of things, we were leaning toward programming in Python and using a NoSQL Amazon database like DynamoDB. We were also open to using SQL or MongoDB from our discussions.
- Exchanged contact information so we can contact Jack whenever if we had any technical queries regarding our project.
