About me
I help businesses turn repetitive document and spreadsheet work into clear, repeatable workflows. My services include Excel and CSV cleanup, data validation, invoice and purchase-order reconciliation, document generation, file comparison, migration checks, and n8n workflow automation.
My portfolio includes independently built demonstrations with sample data, documented outputs, and acceptance checks. Each project starts with a review of your sample files and expected result, followed by a defined scope, an initial working sample, and a checked delivery with handover instructions.
I also bring 24 years of professional aviation experience, with a strong focus on structured procedures, accuracy, and quality control. Based in Doha, Qatar. Available for scoped projects in English or Russian.
