Completely agree. I took a look at all 6 projects under your portfolio and I was underwhelmed with what I saw.
The first thing I noticed is the grammar. I get the feeling that you're not an American by birth, but you should still go through each page and fix the errors. It doesn't impress me to see a smart guy write like a first grader.
And I guess the other gripe I have is the actual designs you came up with. They're mostly uninspired and impractical. You have some really great ideas and some really bad ones. Unfortunately, the great ideas are also hampered by practical problems. The best idea is probably the large touchscreen device for creating and joining events anonymously. The problem is that there are cheaper alternatives (websites can reproduce the same functionality without requiring a large touchscreen display). Then you'd also have to be able to login with something so you can join the events, or else people can screw with you by joining over and over to blow up the numbers when there's actually no one going. This is college we're talking about and there are bound to be a few jerks.
The "Design for Sadness" and "Friend-O-Meter" ones are something kids can come up with. The "Friend-O-Meter" especially has no practical use.
The "Grocery Stop-and-Go" device might be cool if it wasn't so flawed. Groceries aren't updated all at once. I might want to buy some ramen, milk, and eggs (aha, all my examples are random) this week, but only some milk the next because I have enough of the other two. Now, if the labels were on the packaging of the individual items, it might work better. But then you'd have to figure out a way to minimize costs.
And "Textbook on iPad" is uninspired (I'd be shocked if it turns out no one has ever tried this before) and also wrong. Just wrong. In your example, the book is on the left while the dictionary is on the right. Ask yourself: How often is someone going to be interacting with the dictionary? Probably not as much as the actual book. Most people are right handed, so to change pages using your design, they'd have to awkwardly reach over to the left half of the screen and the right half becomes dead space. It's almost never interacted with (why would you need to touch a definition except if you wanted to copy and paste it?) and things would be much simpler if you swapped the two areas.
I admit that I sound really harsh here (and I'm probably a lot off-topic), but it frustrates me when people going into UX design and they completely ignore actual usability. I have no degree in UX design or anything like that (and to be clear, I have zero degrees whatsoever; I'm in high school), but it's people like me that will be using the products. And unfortunately, people like me would be frustrated by the issues that I raised up there. Looking at your resume, I see that you're pretty smart. You just need to start thinking outside of what's already been done and at the same time, finding a way to make it practical and useful.
