My past work experiences mostly relate to start-up companies. For one start-up bio-pharmaceutical company (worked there 4 years), I built their accounting system from ground zero to a full-fledged accounting department: installing accounting software, running payroll and submitting tax forms, 1099 forms, later acquiring ADP for payroll services, monthly book closing, annual audit by Big Four auditors. I've been through the whole cycle of accounting at these start-up firms, and I know how to cut costs and save every penny for companies at the early stage of development. Also, I helped them build up the internal control system and excel in the process of going IPO. I know exactly what investors and auditors look for when preparing the company for going public.
