What I'm looking for

I'm looking to build reliable Python backend systems, automate infrastructure, and work on distributed systems or AI/LLM applications with strong software architecture, observability, and production-oriented engineering practices.

I'm a software engineer building Python backend systems, production-oriented infrastructure, and AI/LLM applications.

At Cloud IB, I worked as a Data Scientist on data science, data engineering, backend web development, APIs, and data processing using Python, SQL, FastAPI, PostgreSQL, Docker, and Apache Airflow.

I maintain a self-hosted homelab where I design, deploy, and operate infrastructure with Linux, Docker, Infrastructure as Code, observability, and CI/CD.

I'm completing a Master's in Information Systems at the University of Belgrade, with a minor in Machine Learning, building on my bachelor's work in Information Systems and Technologies and a final paper on second-hand car price prediction using machine learning algorithms.
