About Sarah

M1 student at ESCP Business School

Skills: Financial Analysis · Professional Writing · Research & Synthesis

Currently in my first year of the Grande École program at ESCP (Top 2 in France, Top 5 in Europe), specializing in Finance (Top 1 globally), I offer my services to companies, consultants, and entrepreneurs who need quality deliverables, delivered quickly.

My experience in Corporate Finance at Société Générale, where I worked on structuring LBOs and transaction documentation, taught me to produce rigorous analyses under time constraints. This is exactly what I bring to my freelance assignments.

What I can do for you:
— Financial analysis and modeling (DCF, LBO, business plans)
— Writing reports, memos, and business content (FR/EN)
— Documentary research and industry summaries
— Proofreading and editing professional or academic documents
— Formatting PowerPoint presentations and Excel spreadsheets
Why work with me:
Academic rigor, responsiveness, and attention to detail. I commit to realistic deadlines and deliver what has been agreed upon, without surprises.
Available for one-off or recurring assignments, 100% remote.
Feel free to contact me to discuss your needs.
