Add some compelling projects here to demonstrate your experience
- Present
As a daily user of MercadoLibre (an Amazon-like service for Latin America) I noticed that prices changed too frequently and often pretended to have inexistent discounts in order to rank better in searches.
One common example of this would be a seller with a product published to a price of $50, then the day after that same seller is able to say "this was $100 yesterday" and pretend to have a half-price discount while keeping the original $50 price, but now he will rank way better in searches.
