Machine Learning Engineer / Essential

Full-time

2021 Mar - 2023 Apr

Yerevan, Armenia

Projects:

Flexport (San Francisco, California) | Vaital (Bellevue, VA)

The project at Flexport involved mapping product descriptions to HS (Harmonized System) descriptions and codes using Natural Language Processing techniques. The main challenge was predicting the HS descriptions and their codes, which are subject to dynamic changes, based on various product descriptions.

The following tasks were performed:

• Developed a multi-label classification model utilizing transformer-based models such as Bert, DistilBert, and Roberta to predict the unchangeable parts of the descriptions.

• Conducted error analysis to identify areas for further improvement of the model.

• Improved accuracy by incorporating techniques like Named Entity Recognition and Natural Language Inference.

• Utilized large language models such as GPT-3 model to predict the dynamic parts of the HS descriptions.

• Implemented an end-to-end pipeline using Flask API.

• Deployed the pipeline on AWS using Amazon SageMaker and Docker containerization.

Roles/Responsibilities: 

• The roles involved in this project were Developer, Lead Machine Learning Engineer, and Mentorship of Junior and Mid-level team members.

Daimler Truck North America (Portland, OR) / Vaital (Bellevue, VA)

The project conducted at Daimler Truck North America focused on data analysis of truck behaviors to gain insights into how customers were utilizing their trucks. 

The main objectives of the project were:

• Analyzing the average types of roads where drivers frequently traveled.

• Analyzing the average speed of drivers.

• Analyzing the electric and diesel prices across different regions.

• Calculating the revenue when drivers transitioned between states during their journeys.

• Visualizing the obtained results using tools like Tableau.

• Roles/Responsibilities: The roles involved in this project were Developer and Data Analyst.

• Language: Python

• Environment: Databricks

• Frameworks and Libraries: Pandas, PySpark, NumPy, SQL, OSRM.
