Bio
Anna Rassoha Nezhalsky
I was Keren's teammate in SAP Israel for two years. During that time we collaborated on two large peer programming tasks, and it was a pleasure to work with her. She is responsible, reliable, resourceful, a good communicator, listens and is open to feedback. Overall, an excellent person to have on your team! She would be a great benefit to any team and I'm looking forward to the next chance I get to work with her!
Ronny Amran
I was Keren's team leader for more than one year. In that period she was showing high technical skills, not hesitating to face any task or challenge. Her passion was to be a UX expert and she took any opportunity we had to gain experience and knowledge in this area. She did it on top of her daily work… What else? She was a significant contributor to team jelling. She is a quick learner. Knows how to listen, to take a feedback and improve. Now I need to find another Keren to my team :-).
