The penny-auction format, briefly
Mummybids.com.sg was a live-bidding penny auction for the Singapore market. In the format, each bid raises the price by a tiny increment and resets a countdown; bidders pay for the bids themselves, and the last bidder standing when the clock expires wins the item — the operator advertised discounts of up to 90 per cent or more on won items. The engineering centre of gravity is the timer: every participant must see the same countdown, and every bid must land in strict order.
Four people, twenty-four days
The original record preserves the delivery detail that makes this project worth remembering: the platform was built by four specialists — a designer, a slicer and two programmers — in twenty-four days, on PHP, MySQL, Ajax and jQuery, with products, auctions, content, banners and members all managed from an admin panel, and security testing completed before launch.
That pace was possible because the scope was disciplined: one mechanic, one market, one well-understood admin loop — and a team small enough that co-ordination cost almost nothing. The slicer role (hand-converting design mock-ups to HTML) dates the project precisely; the scoping lesson does not date at all.
From reference site to own product
The client arrived, as many did in that era, pointing at a famous penny-auction site and asking for “one like that”. What they received was their own product — and the original post records, with evident pride, that they considered it better than the reference they had started from. The pattern repeated across our early auction work: a reference site is a conversation starter; the deliverable is shaped by the client’s market and operation.
In hindsight: a 2026 perspective
The following is present-day editorial perspective, not part of the 2011 record.
Penny auctions have largely left the mainstream, remembered as much for their controversies as their excitement — consumer-protection scrutiny eventually caught up with the format’s economics. As engineering history, though, Mummybids holds two lessons we still apply: timer integrity is product integrity in any live-bidding system, and a tightly scoped brief beats a heroic team for delivery speed. Both lessons run straight through to the real-time platforms in our current auction practice.
