El freelance con que trabajé, es muy bueno. Siempre responde rápidamente, es amable, es cortés y conoce muy bien su especialización. En mi caso nos tocó hacer equipo, en un proyecto en .Net C#, consumir un web service externo dentro del proyecto que era un web service. Tuvo mucha pericia, porque el freelance no tenía acceso a invocar el servicio externo y aún así pudo desarrollar el código adecuado y sin errores.
