AI Automation Engineer | Warsaw, Poland

I build reliable automation systems that remove manual work.

I design backend systems, API integrations, and AI-assisted workflows for startups, e-commerce teams, HR, and finance operations. My focus is simple: turn messy business processes into scalable software that saves time and money.

Availability

Open to long-term remote contracts and part-time retainers.

I am focused on US/EU startups, digital agencies, and business teams that need backend automation, integration pipelines, and AI-assisted workflows without building a large internal team.
