About this Gig

Are you making decisions based on messy, duplicate, or unstructured data?

Messy data leads to expensive mistakes. I am an Economic Analyst and Data Specialist with years of experience handling high-volume, low-error tolerance databases for corporate and institutional clients. I don't just "input" data; I validate its logical consistency.


My Data Cleaning Services Include:

  • Structuring & Formatting: Transforming unstructured raw data into clean, analysis-ready Excel tables.
  • Data Cleansing: Removing duplicates, extra spaces, and standardizing date/text formats.
  • Missing Value Handling: Identifying and logically fixing blank cells.
  • Data Consolidation: Merging data from multiple CSVs or Excel sheets into one master file.
  • Logical Validation: Ensuring numbers are actually readable as numbers and text as text.


Why work with me?

  • C1 Advanced English (Fluent communication).
  • Background in Central Bank data reconciliation and US Healthcare/Logistics Back-office.
  • Strict confidentiality and data security.


Please message me before placing an order if your dataset is highly complex or exceeds 1,000 rows, so I can give you a custom quote.
