Who's behind it
8 years of operations, now in code
No agency process. Before writing code I spent eight years running retail operations — targets, staffing, inventory. Today I design and build systems, dashboards and automations that measure the result instead of guessing.
No mockups. Open them
before believing.

Before you ask
Straight answers
What kind of projects do you build?
Custom web systems, APIs and .NET backends, dashboards, data pipelines and system-to-system automation. The diagnosis may also conclude that building isn't the best path yet — and I'll say so before quoting.
Do you build Power BI dashboards?
Yes: dashboards in Power BI or as a web application, depending on who uses them and how often. The focus is the data source — automated collection and cleaning — so the number is right and up to date without anyone copying spreadsheets.
How much does custom software cost?
It depends on scope, integrations and risk; that's why the quote comes after a short diagnosis. First I define the problem and a first verifiable delivery, then I propose cost, timeline and sequence.
Will you take over a system built by another developer?
Yes. I start by running the system, reading the code, mapping dependencies and protecting critical flows. Technical debt and unknowns go into the plan explicitly, with no blind rewrite.
Which technologies do you use?
TypeScript, React and Next.js on the frontend; .NET and Python for backends and automation; SQL, Power BI and APIs for data. The stack follows from the problem and its constraints, not a fixed package.
Do you work with companies outside Brazil?
Yes, fully remote. Discovery, follow-up and delivery happen online, in English, Portuguese or Spanish.
How do you handle sensitive data and confidentiality?
With least-privilege access, defined channels and data kept out of analytics tools. Cases under NDA show only what was authorised, with the limits of the evidence made explicit.
What happens after the first contact?
I read the context and reply with an objective next step: a diagnosis, a scope cut or the questions still needed to decide.
