The device is on the table. Its LED is breathing. Your phone's system Bluetooth settings can see it. Your app scans, and finds nothing. This is the single most common way a Bluetooth Low Energy integration fails, and it is almost never a bug in your code. It&
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
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
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
Every software product begins with a simple vision. The first few features are straightforward, the codebase is easy to understand, and engineering decisions are made with confidence because the system is still small. As products mature, however, the landscape changes. New capabilities are added, teams expand, delivery timelines become tighter,
Most production incidents don't start with faulty application code. They start with infrastructure changes nobody fully understood: a security policy edited through a cloud console, a manual config update made during an urgent fix, an environment that's slowly drifted away from the documentation meant to describe
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
Pet healthcare records are unstructured by nature. Vaccination certificates arrive as photos taken at a clinic. Blood reports get shared as PDFs. Prescription records get forwarded through messaging apps. Over time, all of it ends up scattered across phones, inboxes, and folders, hard to search, track, or act on when
The signals pets never verbalize A dog developing a low-grade fever won't announce it. Neither will a dog starting to feel dental discomfort. Companion animals are wired, evolutionarily, to mask weakness, a survival trait that predates domestication by a long way. By the time a pet parent notices
