English level: upper
Years of experience: 2

Took a part in number of projects and startups as server and as client developer. Have experience in working in a team as well as with a single projects. 
At the first time engaged in outsourcing and freelancing as full-stack/mobile developer.
Worked in such spheres as data analysis, statistics, machine learning, computer vision and math-related areas. 
Ready to get acquainted with new technologies.
AI engineering, machine learning and web application development.

- 3+ years of experience in Python and C/C++ with strong theoretical knowledge of language capabilities. Practical background in PHP, Java, JavaScript, Solidity. Good understanding of Object-oriented and Functional programming paradigms. 

- Confident in following mathematical domains: probability and statistics, calculus, analytical geometry, linear and matrix algebra.

- Good knowledge of various parametric and non-parametric statistical methods (linear and logistic regression, SVM, Mean Shift, Cumulative density function approach, Decision trees, Neural Networks). Have experience of work with various Python libraries (numpy, scipy, pandas, scikit learn) and R package.

- Excellent understanding of the principles of the operation of Neural Networks (including Convolutional and Recurrent) with experience of their practical implementation (using Tensor Flow and Keras framework). Well versed in many NN optimization methods: L1 and L2 regularization, dropout, artificial expansion of the training data, activation function types (sigmoid, softmax, tanh), various cost-function (quadratic, cross-entropy, exponential) and weight initialization approaches.

- Big experience in application development using various web frameworks: Yii2 (PHP), ZK (Java), Django, Flask (Python). Well familiar with relational and non-relational databases (MySQL, SQLite, PostgreSQL, MongoDB). Confident in the basic front-end technologies (CSS, HTML, JavaScript).
