    Overall , i have more than 15 years of development experience in multiple technical and human environment. For both start-ups and blue chip companies , i did contribute to the success of numerous projects , leveraging on my object oriented background , mainly in Java ( Swing , GWT , SmartGwt , Android ) Of course i am very knowledgeable in web technologies ( javascript / html / css ) and most of relational databases ( MySql , Oracle , SqlServer ..) , JPA persistence framework ( Hibernate ) Capable of communicating in English,French, and to some extent, German and Spanish , i am eager to take every challenge. As a developer , or as a lead developer, as i did before. Whether its about 'standard' web / mobile development , or advanced endeavor ( data mining , principal component analysis ) i am eager to take the challenge. Regards Keywords section for ODesk search ( If i type 'smartgwt' or 'SmartGwt' i don't get the same result so obviously search feature has a case sensitivity bug ) smartgwt About RESPONSIVENESS : I ALWAYS reply to requests EXCEPT SPAM. I got a 'Respond Rarely' evaluation from Odesk due to this. For instance i had more than 25 proposals from the same company which where either not matching my skills or well below my rate. I don't waste my time with this. If you ODesk guys read this , please implement a filter to reject proposals from some clients, or for proposals below a given rate. Thank you  less
