SUMMARY
Data Science graduate (UTM, 2026) with practical experience in data analysis, machine learning, and SQL. Final -
year thesis project involves designing a context-aware recommendation system that integrates meteorological
data (UTCI index) with ML algorithms (Random Forest, scikit-learn) to generate personalized activity suggestions.
Additional hands-on experience f rom a QA internship, where data documentation and structured analysis were
core responsibilities. Looking f or an entry-level Data Analyst or Junior Data Scientist role.

PROJECTS
Weather-Based Leisure Recommendation System
Bachelor's Thesis • Technical University of Moldova • 2025–2026
• Designed a context-aware recommender system (CARS) that maps real-time weather data to personalized
leisure activity suggestions based on individual user pref erences
• Implemented UTCI (Universal Thermal Climate Index) calculation pipeline using OpenWeather API data –
integrating temperature, humidity, wind speed, and mean radiant temperature
• Built and compared ML classif ication models (Random Forest, SVM, AdaBoost) using scikit -learn to predict
user activity comf ort scores across 10 thermal stress categories
• Designed a relational PostgreSQL database schema with normalized tables f or users, activities, weather logs,
and pref erence weights – supporting a dynamic f eedback learning loop
• Developed the backend API using FastAPI (Python)
• Conducted a comparative analysis of 6 thermal comf ort indices and 5+ existing leisure/weather platf orms to
justif y the UTCI-based approach

DomaFlow – SaaS Product Analytics & QA
CyberWhale SRL • Chisinau, Moldova • 2026 • 1 month internship
• Created a structured Tracking Plan with 60+ user events covering the f ull product lif ecycle – def ining event
names, triggers, properties, and business priorities
• Built a User Journey Map identif ying f riction points, user attitudes, and opportunities across key product f lows
(property management, document assembly, CRM)
• Documented 75+ test cases and 20+ bugs with structured reproduction steps and severity classif ication,
maintaining accuracy across a complex multi-module SaaS product
