Easy Computer Academy, LLC

Hello my name is Kris. I’m here because I am passionate about helping non-techie people to overcome their fear of learning SQL.

I know what it is like to not know where to start or whether the time spent learning is worth the effort. That is why I am here to help you to:
- Get started in an easy to follow step-by-step manner.
- Use your time wisely so you focus on what is important to learn to get the most value from your time.
- Answer your questions. Really! Just post a comment and I’ll respond. I’m here to help.

It wasn’t long ago that I was helping a colleague with some reporting. She didn’t know where to start and soon got overwhelmed and lost as she didn’t know SQL.

I felt really bad, as she was under pressure to get some summary information to her boss, the built-in reports were falling short, and to make them better would require her to know SQL. At that time that seemed impossible! It in dawned on me, it doesn’t have to be that way.

Then I discovered a way for anyone with the desire to easily learn SQL. I worked with my co-worker, started to teach her what I learned and soon she was able to write reports and answer her boss’ questions without getting stressed or ploughing hours into manipulating data in Excel.

It hasn’t always been easy. Sometimes the information seems abstract or too conceptual. In this case I’ve found out that a visual explanation is best. I really like to use diagrams or videos to explain hard-to-grasp ideas.

Having video, pictures, and text really help to reinforce the point and enable learning.

And now I want to help you get the same results.

He has been developing software since 1994, back when Mosaic was the web browser of choice. IE 4.0 changed the world, and Michael rode that wave for five years at a .com that was a cloud storage system before the term "cloud" meant anything. He moved on to a medical imaging gig for seven years, working up and down the architecture of a million-lines-code C++ system.

Michael has been at his current cybersecurity gig since then, making his way into management. He still loves to code, so he sneaks in as much as he can at work and at home.

Software Developer (Senior)

Croatia

I’m an engineer at heart and a jack of all trades kind of guy.

For those who care about titles, I hold a masters degree in computing from FER (and a black belt in karate, but that’s another story…).

During the last years, worked in a betting software industry where I made use of my knowledge in areas ranging from full-stack (web & desktop) development to game development through Linux and database administration and use of various languages (C#, PHP, JavaScript to name just a few).

Currently, I’m a senior software engineer at TelTech, where we make innovative communications apps, and I <3 it.

Lately, I’m very passionate about Ionic framework and am currently in the top 3 answerers on StackOverflow in Ionic framework. I wrote a book about Ionic framework which you can get for free on Leanpub: Ionic framework – step by step from idea through prototyping to the app stores.

Other technical writing:

+ wrote a book Getting MEAN with MEMEs
was a technical reviewer for a book Deploying Node published by Packt
was a technical reviewer for a book Getting started with Ionic published by Packt
After writing 300 posts, this is why I think you should start blogging too

Come and see what I write about on my blog.

Paulo Zemek

Software Developer (Senior) Microsoft

United States

I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
