Adding @kolchfa-aws for tech docs review.

Thank you, @ansjcy! Doc review complete - I pushed my changes into your PR. Before we can merge, please do the following:

• Add a bio and picture for Kishore
• Add 3 images marked TODO
• Please retake the screen shots so the font is larger. The font can be smaller than the text on the page but not too much smaller so users can read what's on the image.
  Thanks!

@kolchfa-aws For the font size, that's actually what we're using on the product right now. What do you think, should we tune it just for the blog?

[kolchfa-aws]

@ansjcy Yes, please make the window smaller/font larger when taking screenshots. Users should be able to read what's on the screenshot, ideally on all device types. Of course, the font will still be small on mobile but we should definitely accommodate smaller screen sizes.

@ansjcy @kolchfa-aws - Is this finished? Checking for scheduling purposes.

@pajuric I would love for the images to be higher resolution so the font is larger and users can read the text on the image.
