Programmer, Mathematician, Musician, and Educator

I have been a professional tutor on Wyzant since fall 2012, and a teacher at Cyberninjaz since summer 2015. Prior to that, I had years of experience teaching both formally and informally my friends, classmates, and even a high school AP Computer Science class for a few months. During this time I have tutored countless students and peers of all ages, with many different goals, learning styles, and personalities. It has been an incredibly rewarding experience (and it has definitely kept me busy... [more]


Algebra 1

I'm a junior undergraduate in mathematics. I have taken the standard undergraduate math courses (e.g. multi-variant calculus, ordinary differential equations, and linear algebra), and for over a year now have been taking higher courses in pure mathematics (e.g. number theory, set theory, group theory, and ring/field theory). Many people feel a disconnect between what they learn in algebra, and the math they use in every day life (arithmetic). Algebra is all about abstraction, taking away the "real world"; However I don't think many are ever taught this concept. They are given word problems to try and make algebra "feel" more practical, but that's not what algebra is really about. The power of algebra comes from the abstraction; and, I feel that with a true understanding of what algebra really is, it can become a very beautiful subject.


Algebra 2

Trouble in algebra II can come from both a weak understanding of topics in algebra I and/or from a natural opposition to moving farther and farther away from reality. Abstraction is a hard concept to understand, and I believe the concept all together is ignored in many schools. We're taught this is algebra, and this is how you use it, but we're never taught why we use it, or what makes it so useful. "Why" is a very important question. I believe understanding the "whys" of math is the key to both using it effectively, and retaining the information.


Calculus

I have an associates degree in computer science, and dual majored in math and computer science at UDC for four years, including Calculus, stopping just a few credits shy of completing my bachelors in math and computer science. (I completed every math credit for my bachelors.)


General Computer

I've been playing with computers for years. About 6 years ago the interest moved into webpage development, and then (about 4 years ago) into programming. I now have an associates degree in computer science. Of course over this time I have picked up a fluency in not just how to use the computer, but what it is, and how it works.


Geometry

I have an associates degree in computer science, and dual majored in math and computer science at UDC for four years, stopping just a few credits shy of completing my bachelors in math and computer science, including Geometry. (I completed every math credit for my bachelors.)


Prealgebra

A solid fundamental understanding of arithmetic is very important when moving away from the basic concepts we use every day, to the more abstract concepts of algebra. It's also just as important to learn the language of mathematics, so we are prepared to communicate the higher, more abstract concepts in algebra.


Precalculus

I have been working professionally as a private tutor (through Wyzant) for five years now, teaching various technical subjects to both adults and children, including Precalculus. Moreover, for the past three years, I have been working for a small tech education company as their lead programmer and as a camp counselor where I teach game design, computer programming, web page design, math, and more to kids of all ages (elementary through high school).


Music Theory

I've been playing music since 8th grade where I played trumpet in my school's concert band. Since then I have learned how to play Trumpet, Drums, Guitar, Bass, Ukulele, (and recently, a little alto saxophone). I have performed live on different occasions playing Guitar, Bass, Drums, and Trumpet. I also have experience teaching music to beginners, including teaching Drums, Guitar, and Trumpet, as well as teaching music theory. It is important for any aspiring musician to learn at least the basics of music theory as it let's them learn faster, and better communicate musical ideas with other musicians (especially those who play different instruments).


Trigonometry

I have an associates degree in computer science, and duel majored in math and computer science at UDC for 4 years, stopping just a few credits shy of completing my bachelors in math and computer science. (I completed every math credit for my bachelors.) On top of that, I have been working professionally as a private tutor (through Wyzant) for 5 years now, teaching both adults and children of all ages various technical subjects. Moreover, for the past 3 years, I have been working for a small tech education company (Cyberninjaz) as their lead programmer and as a camp counselor where I teach game design, computer programming, web page design, math, and more to kids of all ages (elementary through high school).


Java

Java was the first programming language I really got involved in. I feel it's currently my strongest language, and it's also the language I use for most of my personal programming projects. Java's cross-platform abilities make it a great choice for almost any kind of program (the main exception being game programming), and it was a great language for introducing me into the world of serious programming.


HTML

HTML can be an interesting and relatively easy starting place to learning how computers work. HTML was, in a way, one of my first lessons in understanding how a computer communicates. It is often over looked as something relatively simple to experienced computer users, but to someone foreign to things like how the internet works, it can be a huge leap forward in understanding. HTML can be fun, and open the door to a whole virtual universe. Now this is often only true if it is learned correctly. One of the major problems with learning HTML is that it has changed so many times since its conception, and many browsers still support the older code. Code that sometimes horrifically violates present standards can pass through okay. While this can be great for a computer user, it can make learning how to write a fast and valid webpage a real nightmare, as well as extremely confuse someone who is new to the idea of communicating information to the computer in a truly unambiguous way.


SAT Math

I have experience teaching math professionally since fall 2012, and non-professionally, all the way back to high school, where I taught my peers in the school "Math Lab" for two years. During this time I have help many students study for the SAT's Math section.


C

C is a language used mainly for low-level programming in environments where higher level languages cannot be used (e.g. microcontrollers), or in situation where optimization is paramount (e.g. operating systems). Because of this, I don't often use C in my own personal projects; however, I do get at least a couple students a year who need to use C, and so I am fairly well versed in it. I also know C++ very well, and C++ shares many of the same qualities as C.


ACT Math

I have an associates degree in computer science, and duel majored in math and computer science at UDC for 4 years, stopping just a few credits shy of completing my bachelors in math and computer science. (I completed every math credit for my bachelors.) On top of that, I have been working professionally as a private tutor (through Wyzant) for 5 years now, teaching both adults and children of all ages various technical subjects. Moreover, for the past 3 years, I have been working for a small tech education company (Cyberninjaz) as their lead programmer and as a camp counselor where I teach game design, computer programming, web page design, math, and more to kids of all ages (elementary through high school).


Elementary Math

Throughout my time working as a tutor on Wyzant, and especially while working as a Summer Camp Counselor at Cyberninjaz, I have experience working with children of all ages, teaching them various subjects, both complex and rudimentary, including math. And although not all of my students have learned to love math (which doesn?t stop me from trying), all children (and adults too) can learn math. And I have the experience to prove it!


JavaScript

Making webpages with HTML, CSS, Javascript, and PHP was the first experience I ever had programming, and I?ve been using these languages regularly since summer 2007. I currently use these technologies and more to build and maintain the Cyberninjaz website, and I have taught all of these languages to many students over the years.


General Music

I've been playing music since 8th grade where I played trumpet in my school's concert band. Since then I have learned how to play Trumpet, Drums, Guitar, Bass, Ukulele, (and recently, a little alto saxophone). I have performed live on different occasions playing Guitar, Bass, Drums, and Trumpet. I also have experience teaching music to beginners, including teaching Drums, Guitar, and Trumpet, as well as teaching music theory. It is important for any aspiring musician to learn at least the basics of music theory as it let's them learn faster, and better communicate musical ideas with other musicians (especially those who play different instruments).


Guitar

I've been playing music since 8th grade where I played trumpet in my school's concert band. Since then I have learned how to play Trumpet, Drums, Guitar, Bass, Ukulele, (and recently, a little alto saxophone). Guitar specifically, I've been playing regularly since late 2014 / early 2015. I mainly focused on learning rhythm guitar (as opposed to lead, although I can teach basic lead guitar). I have performed live on different occasions playing Guitar, Bass, Drums, and Trumpet. I also have experience teaching music to beginners, including teaching Drums, Guitar, and Trumpet, as well as teaching music theory. It is important for any aspiring musician to learn at least the basics of music theory as it let's them learn faster, and better communicate musical ideas with other musicians (especially those who play different instruments).


Web Design

I've been doing web design for about 6 years, and consider myself to know enough XHTML/HTML5, CSS3, Javascript, PHP, and other technologies to be able to write and maintain a professional website. I also take pride in writing websites that are W3C standard compliant. Webpage design is (once you understand it) very fun. So much effort has been put into letting the "lay man" use the internet, both as a user browsing, and as a webmaster hosting. Building webpages in much easier to understand then say making an executable program (like a game, or even something simple like notepad.) But, nevertheless many people don't know where to start, or sometimes worse, they get conflicting information on what to do. There are even computer programs that will write the webpage's source code for you while you drag, drop, and type your webpage in. Even worse, many people don't know there's any other way to make a webpage. Although, these programs are cool if you want a page that is built fast and you don't really know how to do it any other way. They're not, however, going to let you into the virtual world of WWW, and many times it's just not as fun. I can teach you how to (with just notepad and some (online) references) write a webpage that looks just as good. If you want someone to teach you how to use Dreamweaver or FrontPage, that's not me. If you want to learn how to build a fast, and modern webpage, and then know how it works, why it works, and how to edit it... well then, let me teach you.


Discrete Math

Having both a Computer Science major and a Math background, I have a keen interest in, appreciation for, and understanding of the various topics taught in Discrete Math. I took it as a required course as an undergraduate, and I have taught it to multiple students.


C++

I have an associate's degree in Computer Science, and am fluent in C++ and Java. I have been programming since about 2008. C++ is the language of choice in almost all of my college level classes. Also, a good solid understanding of C++ allowed me to better understand how computer programs work at a low level, and how other popular languages work as well.


Computer Programming

Computer programming is really broken down into two parts. Logic and syntax. The logic of programming is something that needs to be only learned once. The syntax however varies between languages, and must be learned for each one. I often consider myself a hobbyist programmer because most of my projects early on were personal and not professional. (I have written a few professional programs too, more recently.) This style had me jumping between many languages. (I have dabbled in over a dozen programming languages.) As such I got a good understanding of programming logic, and really learned the distinction between the logic and syntax. To understand how to program, you really need to understand the logic; any language can be used to facilitate that learning, and I'm willing to teach that logic through whatever programming language you may be interested in (as well as explain the ins and outs of the languages I know to help you make an informed choice.) I have an associates degree in Computer Science, and am fluent in C++ and Java. I have been programming since about 2008.


Computer Science

I have an associate's degree in Computer Science, and am fluent in C++ and Java. I have been programming since about 2008. I'm also a undergraduate math major. Computer science at its heart is really a math subject. To understanding why computers are the way they are, you need to remember that the inventors of the subject were mathematicians. Even in present day the bridge between math and computers science is still there, and with my background I can not only teach you to program, but hopefully explain some of the reasons programming and computers are the way they are.


Linear Algebra

I'm a junior undergraduate in mathematics. I have taken the standard undergraduate math courses (e.g. multi-variant calculus, ordinary differential equations, and linear algebra), and for over a year now have been taking higher courses in pure mathematics (e.g. number theory, set theory, group theory, and ring/field theory). Some aspects of linear algebra can be foreign and daunting. I think that with a better understanding of what abstraction in math means, it becomes easier to grasp really what linear algebra is. In doing so, linear algebra will feel much more natural, and no longer foreign.


Logic

The study and understanding of deductive logic has been crucial in my understanding of higher math (e.g. ring theory). I have also taken courses in college on logic (in general) towards both a math and computer science degree.


PHP

Making webpages with HTML, CSS, Javascript, and PHP was the first experience I ever had programming, and I?ve been using these languages regularly since summer 2007. I currently use these technologies and more to build and maintain a website, and I have taught all of these languages to many students over the years.
