An office administrator at an architecture practice, applying to support a housing trust's executive team

Dear Mr Raghavan,

For four years I have run the office at Ravensworth Architects, a practice of 32 people, and supported its three directors with diaries, travel, board papers and client meetings. Corbel Housing Trust's listing for an Administrative Assistant asks for someone to support a busy executive team and keep its records in order, which is a close description of my current job.

The change I am proudest of is the filing. When I arrived, project documents lived in personal folders and email threads. I set up a shared structure in SharePoint with one naming rule, moved about 9,000 files into it over two months¹, and wrote a one-page guide for new staff. Finding a drawing for a client query used to take most of a morning and now takes a few minutes.

I manage three directors' diaries in Outlook, which often clash, and I send the papers for every meeting two days ahead. I also take the minutes at the monthly partners' meeting and send them out within 24 hours, with actions and names in a table at the top². I look after the practical side too. I process about 120 supplier invoices a month in Xero, keep the office stocked, and organised our move to new premises last spring, which cost us one working day rather than the three we had planned for³.

Corbel's annual report says it is digitising its tenancy records this year. I have done that kind of work on a smaller scale and would like to help with it.

I would be glad to meet at a time that suits you. I can start after four weeks' notice.

Yours sincerely, Mei-Ling Foster
