I think "software developer" describes quite well what I do on a daily basis. Better than the "principal software engineer" that adorns my business card...

(which is still better than the "principal consultant" I had on my card in the early '90s when I was a mere kid - it made a grey haired banker in the city smirk a bit and remark "well, maybe when you have some grey hairs". At least I now have plenty of that!)
