São Paulo, Brazil · Data, AI & product
I'm Enzo Caldeira. I rebuild the digital operations of service companies: design that holds the price, tracking that shows where clients come from, and AI automation at the bottlenecks. I work on product and data at Itaú and I founded Nevran.

Work
Client projects and work inside a bank. Where there is an NDA I describe scope and method. Where the numbers are public, they are there.
Client A technical translation business with corporate clients, a digital presence that did not hold the price, and an internal process running by hand. I restructured the visible front and the machinery behind it.
Client A multi-category retail store that needed to look trustworthy to sell on impulse. I structured the catalogue, page hierarchy and conversion triggers inside the platform.
Corporate The Itaú and Itaú Personnalité app support inboxes take a high volume of customer messages. I built the flow that reads, classifies and routes each one, turning loose text into a queryable base.
Corporate A whole department producing material with no shared standard. I built the application guide in SharePoint and attached an AI agent that helps the team create and fix material inside the standard, without hunting for rules.
Design to build perceived value.
Data to understand what works.
// this intersection is what the market pays a premium for in 2026
I work where the two meet.
My work lives at the border of three things that rarely travel together inside a company: how the business makes money, what the data says, and how that shows up for whoever decides.
Indicator governance, modelling and data products. A loose number changes nothing; a number in the right place changes the conversation.
Triage, routing and reports that refresh themselves. The time returned to the team is the easiest return to see.
Design systems, dashboards and digital presence. How information is presented changes how much it gets used, and how much the service is worth to whoever is buying.
You talk to me and Nevran comes in behind. It is the company I founded to give the work method, contracts and invoicing, with a network of partners and collaborators who join as the project requires: design, development and data.
In practice: delivery doesn't depend on my personal calendar alone, and the client has a structure accountable for it.

22, based in São Paulo, Brazil. I work on data, product and AI at a major bank and I founded Nevran. I study, I build, I document, in that order.
I post weekly on LinkedIn, always the same format: what I did, what I expected, what happened, what I learned.

A fixed 30-day scope, through Nevran, one build at a time. It starts with a short paid diagnosis. If it makes sense for both sides, it becomes an implementation. Pricing is published on the Nevran site.
No. I lead the project and I am accountable for it, but Nevran has a network of partners and collaborators who join as needed: design, development, data. That is what keeps deadlines from depending on a single calendar.
High-ticket service businesses selling to other businesses, where perceived value decides the deal: technical translation, law, accounting, consulting, premium clinics. The pattern is always the same: good service, digital presence that does not match it.
Because much of my work is corporate and under NDA. I'd rather show a few projects explained in depth than a list of logos I can't comment on.
Python and SQL for data, LLMs and agent frameworks for automation, Figma and Astro for interface, Power BI and Power Automate inside the Microsoft stack. The tool changes, the reasoning does not.
No. The site is the visible part. What holds it up is lead source tracking and automation. That's where the return is.
