WORK EXPERIENCE
Python AI Internship - Meduzzen
Dec 2025 – Feb 2026
• Developed AI assistant with RAG architecture using OpenAI APIs
• Integrated embeddings and vector search for context-aware responses
• Implemented audio transcription via OpenAI Whisper API, automatically indexing content for semantic search
• Implemented tool-calling, async processing, and structured prompt design
• Improved response quality through similarity thresholds and fallback strategies
Content Analyst - Jiji
Mar 2022 – Dec 2025
• Developed an AI-powered moderation assistant to automatically classify listings and identify prohibited content using LLMs (OpenAI API), vector databases, and semantic search, significantly reducing manual moderation time
• Collected, structured, and analyzed user behavior data to identify trends, anomalies, and potential risks
• Prepared analytical reports to support moderation decisions and improve platform safety
Data Science Intern - Lemberg Solutions
Jul – Oct 2023
• Processed and analyzed sensor data (accelerometer, gyroscope): artifact removal, normalization, and signal filtering
• Built and labeled a high-frequency dataset and developed ML models (accuracy up to 0.85)
• Compared feature-selection methods and evaluated performance metrics
PERSONAL PROJECT
Ship Segmentation (Kaggle Airbus Ship Detection Challenge)
Developed a U-Net based deep learning model to perform binary segmentation of ships in satellite images.
