Senior Data Scientist
Did research and development in the following fields regarding the product improvement:
- Language detection based on keywords from user searches. Researched state-of-art approaches, created different architectures of possible solutions, implemented approach which significantly improved existing language detection system. Technologies: NLP, Python, Spark, n-grams, Word2Vec, TensorFlow, deep learning.
- Reinforcement learning agent for bid automation. Researched modern RL architectures, processed deep RL articles, proposed a solution based on state-of-art approach, built a couple proof-of-concepts (prototypes on demo environment). Developed a production solution, integrated it to data pipeline (built on Spark and HDFS + S3) and added improvements to it.
Technologies: Python, TensorFlow, Keras, deep reinforcement learning, deep learning, gym (openai).
