I will review and improve your data specification document
About this Gig
Is your data spec document a mess? Missing transformation logic, vague field descriptions, or gaps your developers keep asking about?
I'll review your data specification or source-to-target mapping document and give you a clear, actionable improvement report written by someone who has built and reviewed data specs at PricewaterhouseCoopers (PwC), EY, and TCS on enterprise insurance and banking programmes.
WHO THIS IS FOR:
Business Analysts who need their specs QA'd before handing to developers
Data engineers who inherited a poorly written spec and need it fixed
Project managers whose dev and BA teams keep arguing over what a field means
Consultants who need a second opinion before presenting to a client
Anyone building a data warehouse, ETL pipeline, or data migration project
WHAT I WILL REVIEW:
Source-to-target field mappings completeness, accuracy, and clarity
Transformation logic is it specific enough for a developer to implement?
Data types, NULL handling, and default value definitions
Primary key, foreign key, and SCD type annotations
Business rule descriptions are they unambiguous?
Load strategy documentation full load vs incrementa

FAQ
What format should I send my document in?
Any readable format works — Word (.docx), PDF, Excel, or even a Google Sheets link. If your spec is embedded in a Confluence page or Notion doc, export it to PDF and send that. As long as I can read the content, I can review it.
My document is only a rough draft — is that okay?
Absolutely. Rough drafts are exactly when a review adds the most value. I'll flag what's missing, what's unclear, and give you a priority list of what to fix before you share it with your team or client.
I don't have a proper spec — just a spreadsheet with some column mappings. Can you still help?
Yes. A source-to-target mapping spreadsheet is one of the most common formats I work with. Send it over and I'll review it as-is and tell you what's strong, what's weak, and what's missing entirely.
How technical is your feedback — will my BA team understand it?
Very readable. My feedback is written to be understood by both technical (developers, data engineers) and non-technical (BAs, PMs, business stakeholders) readers. I'll flag issues in plain language with clear examples of how to fix them.
Do you sign NDAs?
Yes. If your document contains proprietary business logic or sensitive data, message me before ordering and I'll sign an NDA before you share anything. This is common in enterprise projects and I'm happy to accommodate it.
What if my document is in a domain you don't know — like healthcare or retail?
Data specification structure and quality principles are universal — field mapping, transformation logic, NULL handling, and load strategy apply across all domains. I don't need to be a healthcare expert to tell you that your transformation rule is ambiguous or your SCD type is undocumented.
Can you also write a data spec from scratch if I don't have one?
That's a separate service. Message me and I'll create a custom offer for a data spec build rather than a review.
