AlexAlex · Septima Systems
I'm Alex Gutiérrez, a software engineer with 9 years in enterprise systems, including banking and payment integrations (Visa, Mastercard and AMEX). I was a Senior System Architect.
Today I run Septima Systems from Querétaro, Mexico, and work remotely with clients in Mexico and Canada. AI helps me build faster; what I deliver is software in production. You talk to me from the diagnostic to the delivery.
Questions
How much does it cost?
US$750 per week. A new system usually takes 2 to 6 weeks; the free diagnostic tells you how many you need. Third-party usage (AI, messaging, domain) is billed at cost.
How fast will I see something?
In 7 days, your first version is in production with your data. Every week after that, another module goes live.
What does “production-grade” mean?
Real people use your system with real data and real money from the first week. It ships deployed, secure, backed up and monitored, documented, with the code in your repository. Not a prototype or a slide deck.
Who owns the code?
You do, from day one. It lives in your repository. No per-user licenses.
What if something happens to you?
Your system doesn't depend on me: standard technologies, documentation, recorded training and the code in your repository, so another developer can continue.
What do you need from me?
45 minutes for the diagnostic; your data as it is today (spreadsheets, Google Sheets or whatever your system exports); one person on your team to test every week; and the access the system needs.
Your first step is 45 minutes.
We find your most expensive bottleneck. If it makes sense to work together, your system is in production in 7 days. If not, you keep the map and an honest recommendation.
You'll hear back from me, Alex.
