  • "Thanks for the question! This is one of my favourite topics because it’s at the core of what we do as PMs DAILY: making the complex simple to drive alignment. I’ve got a structured way to approach this, and I’ll use it to explain payment aggregators - like Plaid - and how they enable Open Banking, with a twist about a technical hiccup I’ve seen in practice. Let’s dive in. I start by assessing the audience. Say I’m talking to a marketing manager at Transak - someone sharp but not techni"

    "To answer this, I will focus my efforts on explaining the most common type of API used in most modern software development applications - the REST API. For the purpose of simplicity, I will also keep the topics of Authorization and Authentication out of the mix. In essence, an API is a group of logic that takes in a specific set of inputs and responds with a specific set of outputs. This is analogous to going to a drive-thru and placing an order for a meal. When you give an API a bunch of"

    "I understand this is more focused on ML. However, I have a system question. If users allow us to access their location, or they send location via text box, could we use CDNs for the search without hitting our database? We only query the database when we have zero information on location. Other questions: does embedding always guarantee information on location? Do we discharge the user images after we return a prediction? I heard the feedback that we should keep it for future learning. What would"
