Hi, I'm Giovanni Muller.
I'm a data analyst with a degree in Systems Analysis and Development and over 4 years of hands-on experience in financial controllership and corporate data analysis.
Before founding Hervller, I worked at companies in the financial sector and in the automotive market — both in manufacturing and retail — where I learned that the biggest challenge for decision-makers is rarely a lack of data. It's a lack of clarity about the data they already have.
I've seen managers make high-impact decisions based on inconsistent reports, outdated spreadsheets and month-end closings that took days. I built Hervller to change that.
Why I built Hervller
In every company I worked at, the pattern was always the same: data existed, but it was fragmented. Finance used one system, sales used another, operations used a spreadsheet. At month-end, someone spent hours consolidating everything in Excel — and the result still had errors.
Smaller businesses and family offices experience this even more acutely. They don't have a BI team, don't have budget for large consultancies — but they make complex decisions every single day.
Hervller was built to fill that gap: to bring real analytical structure to businesses that need genuine financial visibility, without having to build an internal team or hire a big consulting firm.
Experience & background
Focused on financial controllership and data analysis at financial sector and automotive companies.
Strong technical foundation in data, systems, digital solution development and economics.

How I work
Straight to the point
Problem first, technology second
You don't need to understand Python or SQL to work with me. You need to have a financial problem that keeps you from deciding with confidence — that's what I solve.
Deliverables that actually work
I don't deliver decks. I deliver working dashboards, running models and consolidated data — things you and your team can use starting tomorrow.
Full transparency
I tell you what the data shows, even if it's not what you want to hear. Biased analysis to please the client serves no one.
Want to talk?
Tell me your financial challenge. No commitment — I'll do an initial analysis and tell you if I can help.
