Hi, I'm Jenny Saucy.
I'm a backend developer from Switzerland. I'm self-taught and learn mainly by building real projects. I enjoy designing APIs, solving problems, and writing clean, reliable code.
About me
After exploring different paths, I found my calling in backend development when I realized what truly motivates me: solving technical problems and building systems that work under real constraints.
I learn best by building. I've spent the last year mastering backend fundamentals through hands-on projects, focusing on REST APIs, database design, authentication, and testing. I enjoy turning complex business requirements into clean, robust code.
Technologies I work with:
Backend: Python · FastAPI · SQLAlchemy · Pydantic
Database: PostgreSQL · SQLite · Alembic
Testing & Tools: Pytest · Docker · JWT · REST APIs
Outside of coding, I enjoy activities that balance focus and movement — you might find me at a yoga class, climbing at the gym, or even better, in nature.
