He represented Mauritania at the 2004 Summer Olympics, and also set a national record and a personal best of 47.87 on his sporting debut from the 2001 IAAF World Championships in Edmonton, Alberta, Canada.

Running against seven other athletes in heat three, Hmeida crossed the finish line in last place by more than three seconds behind leader Anton Galkin of Russia with a time of 49.18. Hmeida failed to advance into the semifinals as he placed farther from two automatic slots for the next round and ranked no. 58 overall in the prelims. Hmeida was appointed as the Mauritanian flag bearer by the National Olympic Committee (Comité National Mauritanien) in the opening ceremony.
