Два года опыта работы .Net Core + Angular 5-7. Есть опыт работы с Node js и React + Redux с развертыванием на Azure. Так же работал с Xamarin Forms. Решал задачи бинарной классификации текстов, сегментации изображений а также классификации на основе большого набора свойст. Активно интересуюсь machine learning и готов в свободное время развиваться в этом направлении, также готов совмещать обязаности .Net разработчика и ML с даунгрейдом по заробной плате.
