ZDev Studio is a boutique digital agency specializing in web engineering and data intelligence. Founded in 2020, we have delivered over 100 production systems for businesses across the United States, Europe, and Asia.
Our work sits at the intersection of rigorous mathematics and modern engineering. Every engagement is approached with the same discipline — whether architecting a full-stack web application or building a predictive model that drives operational decisions.
We work with a select number of clients at a time to ensure every project receives the depth and attention it deserves. If you have a problem worth solving, we want to hear about it.
I'm a web developer and data scientist based in Brazil. I started building websites in 2020 and have delivered over 100 projects for clients across the US, Europe, and Asia — from small business sites to full-stack applications.
I'm currently doing my Master's in Mathematics at UFSM, specializing in Machine Learning and Time Series Forecasting. I enjoy working on problems that sit at the intersection of engineering and data — whether that's building a fast web app or a model that helps a business make better decisions.
Every project is personally overseen by the studio founder. No account managers, no hand-offs. You work directly with the person building your product.
We move fast but never cut corners. Clean architecture, proper testing, documented code. Built to last, not just to launch.
We measure success by your business results — not by lines of code or hours logged. If it doesn't move your metrics, we keep working.
We partner with companies that have real problems worth solving. Tell us about your project — we respond within one business day.
