It took 3 months, but I'm finally done building the minimum viable product for Tandim. I worked mostly nights and weekends, and I coded the whole thing in Node.js and PHP (Codegniter) since that's that I'm the most comfortable with. In hindsight, there were a few features I built that probably could've waited until later. But I'm excited to start talking to customers and see what they think about the product so far!
