It's just another normal day at SmartyStreets. Jonathan, Founder and CEO, is sitting in their kitchen, eating his bowl of Lucky Charms. Then up walks Mike Whatcott, senior developer and with a problem.
Smarty Streets provide a cloud-based address verification service. If you have a mailing list with a bunch of addresses that you aren't sure of; then you can pump those addresses into the Smarty Streets API, and get back a list of addresses in mailable form, with an indication of whether they are deliverable, vacant, inactive, etc.
Mike's problem is that the field support team need a tool that will take a CSV list of addresses and produce a CSV list of validated addresses.
This video series shows Jonathan and Mike working together, to produce that tool in the `GO`` language.
