Alexander made his senior debuts with UD San Sebastián de los Reyes in the 2007–08 campaign, suffering relegation from Segunda División B. In the 2009 summer he moved to Tercera División side Antequera CF, appearing regularly and subsequently returning to his previous club in the following year.
In July 2011 Alexander moved to RSD Alcalá in the third tier. He finished the season with 38 appearances and 11 goals, being the club's top goalscorer.
On 11 July 2012, Alexander signed a three-year contract with Recreativo de Huelva in Segunda División. After being nearly left out of the squad due to not having an EU passport, he played his first match as a professional on 25 August, starting in a 1–0 home win against CD Mirandés.
On 14 October Alexander scored his first professional goal, netting the last in a 2–5 away loss against Girona FC.

On 10 January 2014, Brøndby activated the buyout clause in Alexander's contract, who signed a two-and-half year contract with the Danish side. On 27 July of the following year he was released.
In July 2015, Alexander signed a two-year deal with CD Leganés in the second tier. He was an undisputed starter for the Madrid side during the season, scoring a career-best 12 goals to help his side promote to La Liga for the first time ever.
