Administrative and operations support professional working remotely, with 10+ years supporting clients through accurate records, reports, and Excel models.
What I'm looking for
As a freelance business consultant, data annotator, and document reviewer, I’ve supported independent client engagements remotely since 2015. I organize client documentation and structured data with accuracy and confidentiality, and manage deadlines across time zones.
I build advanced Excel models and reports using Pivot Tables, XLOOKUP, Dynamic Arrays, and sensitivity analysis to track performance and support business decisions. I also prepare financial summaries, memos, and executive presentations in business English.
For AI training projects with Appen, OneForma, and Remotasks, I’ve annotated text, classified documents, and labeled entities according to detailed guidelines. I’ve also evaluated AI-generated business content and written prompts to improve its quality.
Earlier, at 3M Reclaimer (3M Recuperadora de Metais), I supported administrative and financial routines and prepared sales and operations presentations. At Itaú Unibanco, I maintained project tracking spreadsheets and contributed to process improvement initiatives; I hold a Bachelor's Degree in Business Administration and a Data Analysis Certificate.
