Summary
Python developer focused on AI integrations and intelligent automation. Built an AI-powered nutrition and workout platform (FastAPI, Gemini API) that is now being prepared for production, and spent 4 years building automation software, including computer-vision bots (OpenCV, YOLO) that perceive their environment and act in multi-step decision loops. Looking for my first commercial role in an AI engineering team where I can grow professionally.

Projects
LifeStyle: nutrition, workout and social platform (personal full-stack project, Feb 2026 – present, preparing for production)
Python, FastAPI, Pydantic, SQLAlchemy, SQLite, Alembic, Gemini API, JavaScript, Tailwind CSS, Chart.js
• Added AI meal recognition from text, photos and barcodes with the Gemini API, and built an adaptive workout engine (exercise catalog, intensity algorithm, set tracking, progress charts).
• Designed a scalable async REST API and data model for nutrition, workouts, social features and chat, with strict input validation via Pydantic.
• Ran a security audit: fixed a privilege escalation through the role field, added access checks on admin endpoints and hardened file uploads.
• Set up Alembic migrations and environment-variable configuration; currently preparing the project for server deployment and a mobile client.
Source code available to show during the interview.
