Senior Backend Engineer | Python (Django, FastAPI) | AI-Enabled SaaS Systems

I’m a software engineer with 9+ years of experience building scalable backend systems, SaaS platforms, and enterprise applications. My core expertise lies in Python backend development, cloud infrastructure, API architecture, and AI-powered system integrations.

I’ve worked with international teams across Europe and the US, building platforms in fintech, healthcare, travel SaaS, and large-scale WordPress ecosystems.

Recently I’ve been focusing on building AI-enabled backend systems, including document intelligence pipelines, automated report generation, and AI-powered data processing workflows.
