Can I do my freelancing software development during Aitkaf in ramdan?

Assalam -o- Alaikum, its the first time that i have planned to go for aitkaf in this ramzan. I am doing studying before that so that i can know what is aitkaf and what are its dos/dont's. I cannot find one thing though, is it permissible to do some freelancing work on my laptop during aitkaf, kindly guide me about this. I do software development and i currently have ongoing projects and secondly if i take a ten days holiday, it could hurt my online stats. Jazak Allah.
