About Sylvie

Data Entry Operator & Web Research | Contact Enrichment Specialist (Business Directory / LinkedIn)

I transform your obsolete client files into reliable and usable databases. As a data entry and enrichment specialist, I guarantee 100% verified data from official sources (SIRENE, LinkedIn) to boost the effectiveness of your sales efforts.

Step 1: Identification 🆔 – Using the SIRET number to identify the legal entity on the Business Directory.

Step 2: Cross-referencing 🔄 – Comparing the information found with other sources like LinkedIn to confirm current employee numbers or directors.

Step 3: Normalization 📏 – Standardizing addresses and phone numbers according to your specific guidelines.

Step 4: Validity Test ✅ – Using tools to verify that email addresses are active and not "bounce" messages.

My last mission: +3,000 qualified and cleaned records on NELIS CRM for a real estate sector player, fully remote.

What I offer:
• CRM data cleaning and normalization.
• Deduplication and record enrichment.
• Remote administrative assistance.
• Proficiencies: MS Office 365, Advanced Excel (Pivot Tables), Slack, Teams, Google Drive.

Discretion and data protection are at the heart of my commitment. I handle each file with the utmost confidentiality, as if it were my own professional information.
