About Michael

Michael H.Status: Offline
Financial Automation Expert | Power BI, SharePoint | Vanilla JS, VBA
Lodz, Poland - 4:05 am local time
As a Financial Analyst with a Master of Science in Engineering degree in AI Applications, I specialize in automation.

I combine deep professional experience in accounting for EU-funded projects with the technical proficiency to build effective, automated IT solutions. My core mission is simple: to eliminate repetitive, manual work and allow organizations to gain control over their data.

Tired of time-consuming processes in Excel? I provide clean, robust, and expertly tested code to solve them.

I specialize in:

1. Financial & Data Process Automation (Excel VBA/Power Query to clean, reliable code).

2. Google Apps Script (GAS) & API Integration (Connecting Google Sheets with external services).

3. Building Clean Frontend Logic using pure Vanilla JavaScript (Logic separated from UI).

4. Microsoft 365 Data Solutions (SharePoint List integration and Power BI Data Modeling).

I value a partnership-based approach and a deep understanding of the problem before I start working. My code is clean, logical, and easy to maintain.

I'd be happy to discuss how we can streamline your work and reduce operational risk.
