Internship Student - DataRoot University • Kyiv 2017-10 - 2018-04 Intensive Data Science trainee Program where you learn the theory needed for any full-cycle data science project development: - Python for Data Science (math & libs, python practice. tableau) - Machine Learning (supervised learning, unsupervised learning, scikit-learn) - Deep Learning (deep neural networks, computer vision (CNN), sequence models (RNN), keras, tensorflow) - Big Data & Data Storages (data mining algorithms, data storages, visualization tools) To consolidate the covered material, I took part in the Kaggle competition, where according to results I entered in the top 100. Sentiment Analysis of Social Media in Russian • Kiev 2018-10 - 2018-11 The task was to build a multi-headed a model that’s capable of detecting different types of sentiments in Russian VKontakte posts. For this task RuSentiment dataset was used. RuSentiment is currently the largest in its class for Russian, it contains 30,521 posts and wich are divided into 5 classes. To solve this task I use pre-trained vectors for russian language trained on Common Crawl and Wikipedia using fastText. The best performance was RocAUC score of 0.88 in 5-class classification on the test set. It was achieved by a CNN classifier with in-domain FastText embeddings. Technologies used: CNN, RNN, Logistic Regretion, fastText, Tf-idf, Word2vec

Part-time of full time job with flexible working hours. Professional growth. Office near the metro station. Complex tasks. Small team. Ability to work remotely.

Kyiv · $1000 · Upper Intermediate

Я успешно закончил DataRoot University и на протяжении месяца вместе с командой занимались финальным проектом. Он заключался в построении агрегатора статтей, который выдавал релевантные статьи по ключевым словам. Также пробовал себя на различных наборах данных из Kaggle. В этом году написал успешно защитил бакалаврскую работу связанную компьютерным зрением. Она заключалась в анализе различных существующих алгоритмов масштабирование изображения, построения нейросети которая занималась этой задачей и сравнение качества всех рассмотренных методов. Хочу найти дружных коллектив, который любит сталкиваться с трудностями и решать их. Важен свой личностный рост внутри команды. Хочу реализовывать самые безумные идеи, которые казались нереальными и создавать что-то новое.

Написал объёмную бакалаврскую роботу на тему компьютерного зрения и различных методов масштабирования изображений. Однажды прошел на Coursera направление Deep Learning от Andrew Ng, которое состоит из 5 курсов всего за неделю.

Хочу максимально избавиться от рутинной роботы, чтобы было как можно больше времени на максимальное погружение в конкретные проекты. Очень интересно заниматься машинным обучением. Обожаю язык Python и постоянно нахожу что-то новое. Всегда готов учиться чему-то новому.

Junior Python Developer 

Remote work, Ukraine · $500 · Less than a year of experience · Upper Intermediate

I am programming on Python more than a year, know the basis of OOP, had been working with Google services like Google Map API, Python libraries such a numpy, re, also wrote scripts on Python. Last project working with Python was creating an application for character recognition using PCA. I was supposed to develop an effective algorithm (you can see it`s a realization on my Git Hub) using linear algebra methods.

Python, Linux, Git, MySQL, OOP, HTML, CSS, REST API, Algorithms, Linear Algebra, Jira

I`m looking for part-time (better if it will be remote) job to combine studying with work. I'm expecting precise requirements and rules, friendly team, which are in passion of what are doing.

I am a master student at Ukrainian Catholic University. I am enrolled into Data Science programme and I am currently pursuing my master thesis. At the uni we had many ML/DS related courses, many of which were ended by the project, which was done either in teams or alone. Constant participation in group projects has developed strong team-playing, problem solving and communication skills. On previous place of work I had a project where the task was to track a laser pointer with a camera, which was successfully solved. Furthermore, in one of the courses at UCU students split in teams and participated in a Queen's Innovation Challenge. Particularly our solution to the problem organizers had posed was to detect and prevent potholes on the roads. For detection we used computer vision and I was in charge of creating a model that would be able to classify photos into 2 classes: with a pothole and without one.
