What I built
Mirror Technology is a tech retailer in Bogotá selling phones and accessories from brands like Apple, Samsung, Xiaomi and Tecno. I designed and built their entire online store.
The brief wasn’t just “a page to sell from.” It was a store their own team could run every day without depending on anyone.
The problem
Selling phones is nothing like selling t-shirts, and that was the starting point.
Every phone has its own serial number. When a customer comes back with a problem, the shop needs to know exactly which unit they sold them in order to honor the warranty. A normal online store doesn’t keep that record: it only knows there are “five left.”
Stock has a similar catch. There’s no such thing as “five iPhones”: there are two black 128 GB and three blue 256 GB, and each combination sells out on its own.
And then the everyday problem: every time they wanted to change the homepage promotion or feature a different phone, they had to ask someone. A store you can only update by calling the developer is a store that almost never gets updated.
How I solved it
Stock is tracked one unit at a time. Every phone enters the system with its serial number. What the store shows as available isn’t a number typed by hand, it’s the real count of the units they hold. When an order ships, the exact unit that left is recorded, and that trail is what backs the warranty later.
The client runs the homepage. From the admin panel they pick which phone headlines the page and upload a photo for each available color, so the phone changes on screen when a visitor taps a color. The featured promotion —image, copy, colors and button— is edited there too. None of it goes through me.
Payment fits how the shop sells, not the other way round. Buyers can pay online, or reserve and pay cash when they collect at the Bogotá location. Home delivery orders ask for an ID document up front, because that’s what the shop requires to hand over a phone safely.
The result
A store with a white background and gold accents, worthy of the products it sells, with the catalog organized by brand and product type so someone finds what they’re looking for in seconds.
More than half the work here isn’t visible from the outside: it’s in Mirror Technology’s team being able to run their store without depending on me. That, to me, is the difference between handing over a website and handing over a tool.
