Leon Jevtić

Software developer, in my final year at HTL Salzburg.

I'm Leon, in my final year of the IT department at HTL Salzburg. I like building software for the things that get in the way every day: forms nobody wants to print, bookkeeping, settling up after a holiday.

Right now I'm working on my diploma thesis.

Projects

  • liquidstack

    Bookkeeping for sole proprietors in Austria, as a web platform and an Android app: scan receipts, track income and expenses, handle VAT. My diploma thesis, in a team of four. My part is requirements, the database, validation, and receipts that can no longer be changed afterwards.

    Since 2026, with Go and PostgreSQL

  • HTL App

    The school uploads a PDF form, students fill it in online and sign it with a code sent by email. With Microsoft login and in eleven languages.

    2026, with Python, FastAPI, React, and PostgreSQL

  • TripApp

    Records rides by GPS, with speed, distance, and a history on the map. An app for me and my friends.

    2026, with Flutter, Firebase, and Google Maps

  • Rechnungsverwalter

    Shared travel costs: who paid for what, and who owes whom how much? With trips, expenses, and settlements, in German and English.

    2026, with Next.js, React, and SQLite

  • Rechenzentrum-Leitstelle

    Monitors a simulated network of servers and switches: reports outages, shows which devices are cut off, and finds the fastest route. A console answers questions through a local language model.

    2026, with Python, FastAPI, PostgreSQL, and Ollama

Python with FastAPI, Go, TypeScript with React and Next.js, Flutter, PostgreSQL, and Docker.
