My team got new state-the-art solution in field of anomaly detection on video survaillance; also we developed accurate hierarchical classifier of tender's product, using it's description.

Looking for opportunity to join team of professionals to deliver results with best quality(doesn't matter it is product or outsorce project). Always want to improve my skills in machine and deep learning, especially Computer Vision/NLP/Anomaly detection fields. Don't looking for BI/Data analysis position.

Junior Python Django Developer, interesting in ML 

Kharkiv · $300 · Less than a year of experience · Intermediate

Here only work experience (3 months as junior data scientist): During internship in company, create dashboards in Google Data Studio. Wrote scripts to gather information from one source (using scraping) to another (example - from one API to Google Spreadsheets). Have a few tasks with Postgresql. If interested, you can get more information from my resume (and links to my profiles with completed projects also are here).

Python, Pandas, OpenCV, Django, REST API

Want to make REST API in Django (currently learn this framework), creating websites using it. Make data analysis and data visualization through graphs and dashboards. Especially using plotly or Dash to do it. Gather data from different API and scraping. Implement machine learning models. Simple computer vision tasks.
