Neutral News Aggregation — Bias Detection & Multi-Source Classification Pipeline

TextClassification
Designed and developed a news aggregation system focused on detecting and classifying media bias across European multilingual sources. Built data pipelines for collecting, cleaning, and structuring news articles from multiple RSS feeds and news APIs (Mediastack, NewsAPI, GNews). Applied NLP-based classification to categorize articles by political leaning, source reliability, and topic clustering. Developed annotation guidelines for bias labeling across dimensions including framing, omission, and language tone. Utilized Python, PostgreSQL, and LLM APIs for automated pre-labeling and human-in-the-loop validation. Research grounded in university-level methodology for ensuring annotation consistency and inter-rater reliability.

Development and Optimization of RL Agents for Algorithmic Trading Strategies

TextData Collection
Designing and evaluating reinforcement learning environments for automated trading strategies. Key responsibilities included sophisticated feature engineering for the agent's state space and the construction of robust reward functions. The approach balanced yield optimization with rigorous risk management (e.g., drawdown minimization). This prepared the models for high volatility and rare market edge cases, as financial markets are highly stochastic and rarely behave with absolute predictability.
