Description

Couple of months ago, I had to give my understanding of concepts on a few design patterns to my team at my ex-employer’s place.

To give you a fair idea and a little background story, my team size was 10 and was full of good experienced people having approximately 6+ years, along with them an architect and a team lead and I was just about 3+ experienced guy. It's not easy to give a presentation to the wise ones you see.

My biggest worry was that although you can find a lot of resources and books on design patterns, you just can copy from them and blabber something about it, but I couldn’t do so because the audience was smarter than me.

But hey, I was lucky enough to choose how many patterns I should be talking about within a time frame of around 30 mins.

So I took 4 good ones which are not soo hi-fi and not so easy to talk about. But as I hoped for, it wasn’t easy to understand from online resources, atleast for me. I had to sit for 2-3 late evenings skimming through at-least 10 resources (if I remember correctly) from websites to blogs to books. Basically, I wanted to prove my technical ability and follow the KISS principle by giving a simple understandable presentation rather than reading a copied slide or mugged up resource content which anyways would fail because any wise guy will bust you for that. ;)

So doing an exhaustive reading and understanding in detail about each pattern, I was supposed to prepare not only a slide presentation, but I also had to write equivalent sample code.

So in this post, I won't upload any code because it's not that important, nor that great (leave a comment if you want, and I shall upload it), hence I am only providing a link to the slides here:

Now I must say, my presentation was well received/accepted and they even thanked for keeping it simple and crisp.

Finally, hard work paid off.

I thought that sharing this presentation would help someone who might be having problems like I faced earlier. Hence this post.

Thanks.
