CS Club Treasurer.
Making budgets legible, expenses traceable, and financial decisions easier for a student organization to make.
Trust starts with a clear ledger.
As CS Club Treasurer, I support the financial side of club activities: building budgets before commitments are made, recording expenses, organizing reimbursement information, and comparing actual spending with the plan afterward.
This work is not only about arithmetic. It is about making sure organizers have a realistic picture of what is possible and a reliable record of what happened.
A practical financial workflow.
Start with a useful budget
Break an event into realistic cost categories and quantities so decisions can be made early.
Record the details
Keep purchases and supporting documents organized while the event is active.
Check plan against reality
Compare actual expenses with the proposal and make discrepancies visible.
Close the loop
Produce a clear post-event account that the team can use as a reference next time.
Example: Club Expo.
For a CS Club Expo activity, the proposal budgeted 200 booklets at ¥0.70 each, for a total of ¥140. The post-event report confirmed that the expense stayed within that ¥140 budget. It is a small line item, but a concrete illustration of the complete cycle: estimate, purchase, document, and report.
For larger events, I use the same discipline at a different scale. HackDKU is presented as its own case study because the event work involved much more than its planning spreadsheet.
Only aggregate financial information is shared here. Internal records and personally identifying payment details are not published.
