Over mij
I am an Argentine business owner with hands-on experience in construction budgeting, Excel workflows and structured operational data. I help clients validate, clean and organize JSON, CSV and spreadsheet files for reliable use in apps, automations and business processes.
My work focuses on clear requirements, reproducible checks and accurate deliverables. I use AI-assisted tools and tested local workflows, and review each result before delivery. Please provide only data you are authorized to share.
