I make accounting and technology speak the same language — and I make sure the accounting is actually correct.

Most accounting software fails on the same thing: the logic underneath is wrong. The chart of accounts doesn't hold, VAT is handled as an afterthought, postings don't reconcile, and edge cases that any bookkeeper knows by heart were never modeled. The product works in the demo and breaks in production. I'm the person who finds that before your customers do.

I combine hands-on accounting experience with technical understanding, so I can sit between your developers and the accounting reality they're building for.

What I do:

Accounting logic for fintech products

I pressure-test the accounting engine in your software: chart of accounts, VAT and tax codes, double-entry logic, reconciliation, period closing, and document handling. I translate accounting requirements into specifications your developers can build from — and catch the errors that turn into support tickets and broken trust later.

Domain validation

I check that your product solves a real accounting problem rather than digitizing an old manual habit. I bring the operational reality of bookkeeping, controlling, and reporting into your product decisions.

Accounting and finance advisory

Setup and structuring of chart of accounts, VAT configuration, controlling, and reporting — for fintech companies that need their own financial foundation in order, or for accounting firms moving from manual operations to automated advisory.

As a strategic link within the region’s leading accounting firms, I have translated technological potential into tangible business gains for both business services and their clients.

My focus was ensuring that software never stood alone but was always anchored in the actual needs of the business.

Selected Achievements:

- From Resistance to Ownership: I led the transition to new digital workflows by fostering understanding rather than just implementing systems. This transformed the internal culture, turning employees into the driving force behind further digitalization.

- Strategic Translation: I served as the bridge between client business objectives and technical IT possibilities. I ensured that technology was selected and shaped by real-world requirements—not by the limitations of the software.

- Operational Excellence: By streamlining internal processes and removing unnecessary "system noise," I significantly increased efficiency within business services. This resulted in reduced overtime and a sense of calm during peak seasons.

At a technology-driven accounting firm, I established the foundation for a scalable finance function. My focus was on stripping away complexity and replacing heavy manual processes with automated flows that directly impacted the bottom line.

Key Achievements:

- Increased Profitability through Simplification: I executed a technical consolidation that cleared the system landscape and removed manual bottlenecks. This led to a significant boost in revenue per employee, as the existing staff freed up capacity to handle larger volumes without increasing their time consumption.

- Strategic Restructuring: I led a comprehensive organizational streamlining focused on the core business. By divesting non-profitable units and optimizing the setup, I secured a more robust and profitable company that maintained revenue on a sharply focused foundation.

- Bridging Complex Client Needs: I ensured alignment between advanced client requirements (including SaaS and FinTech) and our internal delivery. I made sure that the clients' technology and our accounting practices integrated flawlessly.

- Advanced Reporting and Automation: I established the framework for automated financial reporting for complex business structures, minimizing errors and manual work.
