Raphaël Onillon

Looking for a rigorous junior profile to support you in management control, finance, or accounting tasks? I can help you structure your data, automate your Excel files, formalize your internal procedures, or carry out concrete financial analyses.

I am currently in my 2nd year of a Bachelor's degree in Economics-Management (Ecogestion), and I am currently undertaking a one-month internship at the Laboratoire Science et Nature (LSN), in the Management Control, Finance & Accounting department. I work autonomously on missions with direct added value:

-> Consolidation of multi-entity financial data (7 entities of the Pégase Group) using complex Excel files with VLOOKUP / XLOOKUP / SUMIF

-> Monthly monitoring of internal transfer prices (PRI) on Cegid ERP - analysis of budgeted vs. actual variances

-> Creation from scratch of a monitoring tool for 2026 investments (3 linked tabs, drop-down lists, automated formulas)

-> Comparative analysis of long-term leasing vs. travel expenses for a vehicle fleet (2-tab Excel file, break-even point, projected savings)

-> Formalization of internal procedures (purchasing, receiving, supplier invoicing) in Word documents with Cegid screenshots

What sets me apart is my ability to quickly master tools, produce clean and directly usable deliverables, and integrate into existing teams without a long adaptation period. I am used to working on real files, under professional conditions, and not just in academic exercises.

Types of tasks I handle:

Excel dashboards, accounting data restatements, expense analyses, budget monitoring, procedure formalization, assistance with management reporting preparation.
