I help businesses use the data they already have.

Scroll for the storyWhere it started
In school, I loved economics and accounting.
Then I started looking at how real businesses actually run.
The gap
Most of them sit on data they never use.
So I moved from economics into business analysis and data science, to close that gap.
First real fix
Month-end close, 30% faster.
As an accounting intern at Basil & Alred in Tanzania, I automated the monthly reports in Excel and rebuilt the dashboards leadership read.
Same habit every time: messy data in, a decision someone can make out.
90%
less time to build a report
Judging a company means working out dozens of ratios from its financial statements. My app does it straight from the Excel files, compares companies side by side and flags warning signs in red. Here, Boryszew carries the most debt of the three.

60%
less time on one-off reports
Patients, treatments and payments lived in separate files, so every question meant matching them by hand. I put them in one database with a live dashboard, so managers can see revenue month by month on their own.

in delay penalties, across 300,000 flights
Airlines pay penalties for late flights, but a huge flight log doesn't tell you where to look. My Excel dashboard filters delays and penalties by airline and state in one click, and points straight at California.

groups of look-alike countries
Comparing 27 countries on six measures at once is too much for any table. I pulled World Bank data and let an algorithm sort the countries into groups that behave alike, in a chart you can explore.
