How Ada was born — software for the gold & jewelry trade

Ada started with a simple problem — a goldsmith's accounts kept in a paper notebook. This is the story of building a suite that several shops now run on every day.

The first time I walked into a goldsmith's shop and looked behind the counter, I found a notebook. Karat, weight, wages, invoices — all of it written by hand. The owner was experienced and sharp, but to find one old customer's account he had to flip back dozens of pages. That was the moment I realized this trade had been left behind: none of the big software companies had built anything that really fits it.

I started by asking questions, not by writing code. I asked several goldsmiths how their day goes, where their time gets wasted, and what annoys them about the software they had tried. The answers were similar: the tools were expensive, or they depended on the internet — and a shop's internet is not always there — or they simply didn't understand gold math. Karat, wages and settling accounts with the refinery are not things a developer can understand without sitting next to the daily mess of this trade.

One early decision shaped everything: Ada must work completely without the internet. The data lives on the shop's own computer, and whenever the connection returns, it syncs to the cloud safely. The owner never has to worry about a dropped connection or someone else's server; their whole world is one simple, reliable program.

After accounting came the workshop — orders piling up and every piece needing to be tracked. Then the refining and assay lab, then software that drives goldsmithing machines. The same rule repeated every time: sit next to the person who does this work every day, watch where their hands go, and only then build. The result is that Ada today has several workspaces that switch with a single toggle, all sharing one customer record — from barcoded invoices to the Jalali calendar.

The most important lesson Ada taught me: good software is not the one with the longest feature list. It's the one where, after a week, the shop owner says "I can't work without it anymore." Every time a new customer says that sentence, it pays for every late night of this journey.

And this is only the beginning.
