About Onesime

Business accounting and finance consultant with over 13 years of experience in the corporate world. I particularly appreciate "automation", data quality related tasks, and the simplification of financial and accounting processes.
I have worked in various sectors: services, real estate, construction, and healthcare. These diverse experiences have developed my rigor and my taste for financial management.
Today, I aspire to offer my skills in SQL and VBA Macros to companies that need to implement or improve business or financial management tools.
