You will get a cleaned, deduplicated, and normalized CRM database
Rising Talent
Project details
Messy databases cost you money, ruin your email deliverability, and make accurate analytics impossible. Whether your data is sitting in a raw SQL database, a messy Google Sheet, or a bloated CRM, I will clean, standardize, and restructure it so you can actually use it.
I do not just manually stare at spreadsheets. As a Database Architect, I build custom Python and SQL scripts to process your data with absolute precision. I will identify complex duplicate entries, standardize formatting across thousands of rows, validate data types, and normalize your tables so your system runs lighter and faster.
What is included:
• Deduplication: Merging or removing duplicate records based on your specific logical rules (e.g., matching emails, fuzzy name matching).
• Standardization: Formatting phone numbers, capitalizing names uniformly, and fixing date structures.
• Data Validation: Removing invalid emails, identifying missing critical fields, and stripping hidden characters that break your imports.
• Normalization: Structuring flat, repetitive data into proper relational formats if you are migrating to a new database.

Steps for completing your project
After purchasing the project, send requirements so Khaled can start the project.
Delivery time starts when Khaled receives requirements from you.
Khaled works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement Gathering & Secure Data Transfer
You provide the raw data files or CRM access securely. We will clarify your specific rules for deduplication, formatting standards, and what constitutes a priority record when merging conflicts.
Deep Data Audit & Structural Profiling
I analyze your dataset to identify hidden issues. This includes finding formatting inconsistencies, detecting invisible characters that break imports, and mapping out the complex duplicate patterns.
