A pipeline written as a script is a promise that nothing will go wrong. Modeling it as a directed acyclic graph is what you do after something does. Every multi-step pipeline starts as a function. Fetch the data, clean it, score it, summarize it, store the result, notify someone. Six
The problem Look at how the app handles daily habits today. The quiz has a streak. Paw Pulse gives you a fresh insight about your pet once a day. The journal keeps a running timeline of what happened, day by day. On the surface these look like three unrelated features.
Whenever we build a new website feature, our first instinct is usually to think about a backend. We start planning REST APIs, database tables, authentication, deployment pipelines, and server infrastructure. For many applications, that's exactly the right approach because those components provide the flexibility and scalability needed for
When most people think about the engineering behind a pet wearable, they imagine motion sensors, batteries, AI models, or health analytics. Those are the visible innovations. What they rarely think about is the invisible layer that determines whether any of those innovations reach the user at all: Bluetooth connectivity. A
Before a page shows up in search results, a search engine has to know it exists. That's indexing, and it normally happens through crawling: a bot follows links from pages it already knows about, reads your sitemap, and revisits your site on some schedule it decides for itself
One message stopped testing cold: "my bowl is not getting connected to wifi." We have an FAQ that answers exactly this. The bot escalated anyway. No answer sent, just a ticket sitting in Slack for someone to pick up six hours later. Nothing was broken, technically. Retrieval ran,
Deeplinks Are Distributed Systems in Disguise Why application navigation behaves more like distributed messaging than request routing. For years, I thought of deeplinks as a routing problem. A URL came in, it was parsed, and the application navigated to a screen. It felt deterministic—almost boring. That assumption lasted until
Performance is often associated with page speed. While loading speed is an important part of the user experience, it isn't the whole story. A page may load quickly yet still feel frustrating if elements shift unexpectedly or interactions are delayed. Exploring a Next.js application that appeared fast
Every engineering team runs into the same wall eventually. A product starts with a clean codebase, a small team, and a clear vision. Features go in fast, decisions get made pragmatically, and development moves quickly. Then growth happens: more developers join, more requirements land, more integrations get bolted on. Changes
A pet parent opens EverWiz chat and asks, "Is Milo overdue for his rabies booster?" A generic LLM can write a thoughtful essay about rabies vaccination schedules. What it can't do out of the box is look at this specific pet's actual vaccination card
