Managed teams of 2 to 3 Data Scientists working on custom projects.Led and developed a POC project on e-commerce data, which is soon to be officially launched and will be one of the biggest new additions to the company's portfolio.Was a lead data scientists working directly with clients, understanding their needs and delivering best solution to their needs.

Was part of the team who refactored R code into python and moved all of the ML pipeline to GCP environment:- BigQuery for data manipulation and quick access;- Google Storage for back-ups and ML models;- DataFlow for computationally heavy python code parallelization;- Cloud Composer for task orchestration.Developed product matching ML algorithm that used textual and image data.Worked on custom client requests for data preparation and extraction.

Developed and optimized ML code that predicted product brands from textual information.Deployed and maintained various services through Docker containers.Was responsible for running bi-weekly ML pipelines using Airflow DAG.

As a board member I participate in decision making steps plus their fulfillment. Lithuanian Society of Ultrarunners manages national team's participation in World Championship events on the road and in the mountains.

Our other goals are to increase popularity of trail and ultra running at the national scene and raise the quality of organizing such races.

Worked on iOS and android mobile game application development.Implemented various game mechanics and event handlings, like in-app purchases, logins, DLC updates, tutorials.

Created a numerical model for improved estimation of the ballistic coefficient of space debris from TLE orbital data.
