Hi, I'm
Leonid Tots
Backend Developer
Software Development student focused on backend engineering. I build APIs and server-side systems using Python, FastAPI, and PostgreSQL.
About
I'm a Software Development student with a focus on backend systems. I write Python — building APIs, automating tasks, and working with databases. My studies also cover systems programming in C and C++.
Beyond coursework, I work with FastAPI, Flask, PostgreSQL, MongoDB, Docker, and other tools to build complete backend solutions.
This portfolio is part of that process. Every project here is something I built and understand.
