About Me
Helping Management Accountants to uncover what Excel is truly capable of
Hi. I’m Agnieszka Nyka, a management accountant (ACCA part-qualified) with a Master of Science in Applied Mathematics and over 25 years of hands-on experience in management accounting, group consolidations, and inter-company transactions across a variety of private equity-backed companies.
But spreadsheets? That’s where my real story begins.
I met Excel in 1999 (the ancient version Excel 97!) and I took to it like duck to water. I’ve been building smart Excel solutions to make my work easier from the very beginning. On my very first office job, I got the label “Excel Expert” before I’d even fully earned it. I’ve been living up to it ever since.
I didn’t learn Excel automation from a course - there simply wasn’t one. I learned by building things. Breaking things. Rebuilding them better. That journey is what makes me the expert I am today.

What I Do Now
I design and build custom Excel-based systems that:
Eliminate repetitive tasks and reduce manual input
Modernise old spreadsheets without losing what works
Streamline reporting and automate bookkeeping processes
Integrate Excel with accounting platforms for more accurate, scalable outputs
While I specialise in QuickBooks Online, I can adapt my methods to work effectively with whichever accounting system you rely on.
Whether I’m improving a month-end close process or transforming a legacy file into a modern tool, I always aim for one thing: simple, smart, sustainable automation.
Lots of people know Excel.
A few know accounting.
Very few know both - and fewer still know how to build solutions that actually fit the way accountants work.
What I bring to the table is:
What Makes Me Different?
The practical insight of an experienced accountant
The logic and structure of a mathematician
The mindset of a self-taught developer who loves a challenge
The discipline of a competitive ballroom dancer (yes, really)

From Timetables to Puzzles
A CEO of a ski academy once asked me to build a school timetabling system that no off-the-shelf software could handle saying: “If anyone can do it, it’s you.” And just like that, the challenge had my name on it.
It was a weekly timetabling system for an elite ski school - impossibly complex, full of conflicting constraints and real-time changes. I had to explore optimisation algorithms and build a system that adapted as fast as the weather. There were not no numbers, no costs, no profit - just rooms, timings, athletes, chaos… and Excel.
This project showed me what Excel can really do - and how much more is possible when you stop asking “Can this be automated?” and start asking “How can I make it work?”
I loved every minute of it. When it ended, I missed the challenge so much that I started solving traditional logic puzzles in Excel - just for the joy of it. Turns out, puzzles sharpen the exact creative problem-solving skills that I now bring into accounting automation every day.
Beyond the Spreadsheets
When I’m not in Excel dealing with pivot tables, I’m almost certainly on a dance floor pivoting in a completely different way.
As a ballroom dancer, I’ve learned that great performance comes not from flashy moves, but from mastering the fundamentals.
Automation is no different. No macro, add-in, or Power Query trick can replace a deep understanding of the basics - and the confidence to apply them well.
Shall We Dance? I Mean - Shall We Start? ;-)
When I started automating, I had no course to follow - so I built the knowledge myself, one project at a time.
Now I’ve turned that experience into the kind of tools, systems, and resources I wish I had back then.
If you’re ready to stop copying and pasting, and start building smarter ways to work, I’d love to help.
