After a relatively successful amateur career where he had won a number of Iberian championships and several podium finishes at various W.A.K.O world and European championships, Luis made his K-1 debut in 2004. In a rather bizarre tournament appearance he made it to the semi-finals at the MAX event in Lisbon as an injury replacement only to face his older brother José who showed little brotherly love by promptly stopped him in the second round. Luis had more success at the next regional MAX event across the border in Spain, stopping his two opponents before losing to home fighter Abrahan Roqueñi in the final.
After his MAX appearances Luis joined the (then) fledgling Thai & Kickbox SuperLeague in 2005 but had little success in his two matches with the promotion losing both by decision. A return to K-1 MAX in 2006 resulted in a tournament victory in his hometown of Lisbon although the regional win would not mean a place at that year's K-1 MAX final. He encountered the same issue later that year with the It's Showtime organization winning their 75MAX tournament in Portugal but failing to be invited to the final to be held in the Netherlands the following year. In 2009 he won another tournament in his home town, this time winning the World Kickboxing Network (W.K.N.) eight man K-1 rules tournament.
On December 15, 2012, he lost to the eventual tournament winner Karim Ghajji on points in the semi-finals of the WKN 75 kg Full Contact European Grand Prix at Full Night 6 in Agde, France.[4]
He lost to Bakari Tounkara on points at FK-ONE in Paris, France, on April 20, 2013.[5]
