Work History
Data Scientist
7 Generations
08.2024 - Current
- Model Optimization:
Evaluated 8-10 loss functions for an existing model, implemented them in the pipeline, tested 9 models, and identified the best loss function, improving metrics by 10-15%. - Feature Engineering:
Conducted in-depth research on TLS payload, Client Hello, and Server Hello messages.
Developed a parser to extract fields from byte strings and introduced new features, boosting model performance. - Prompt Engineering:
Created a pipeline for website categorization using OpenAI API to predict themes, geographies, and languages for web services.
Tested 10-12 prompt engineering strategies (e.g., Chain of Thought) to optimize predictions. - Labeling Tool Development:
Developed a user-friendly tool using Selenium, Streamlit, and Tshark to simplify and accelerate labeling.
The tool automates dataset processing, pcap generation, and dynamic selection of categories (e.g., Geo, Theme, Languages, App Platform), reducing errors and increasing labeling speed.
