Marius-Jascha Magiera

You want to integrate AI into your product – and need someone who builds the entire application, not just the model. That's exactly what I do.

I'm Marius – AI Engineer, Physicist (MSc), and former SaaS founder. I combine technical depth with entrepreneurial thinking. Before I brought AI systems into production, I developed complete SaaS products from scratch – touching every layer myself: Frontend, Backend, Data Pipelines, Cloud Infrastructure. This is not a nice-to-have: Anyone who wants to deliver production-ready AI features needs someone who also masters the surrounding application.

I deliver LLM integrations, RAG systems, and AI-powered applications – end-to-end. Plus, a broad full-stack background:

→ Frontend: React, TypeScript, Next.js – performant UIs, data visualization, seamless integration.

→ Backend: Python, FastAPI, Microservices – robust APIs, efficient data processing.

→ Data: ETL/ELT pipelines, Data Warehousing (PostgreSQL, BigQuery), BI (Looker, Tableau, Power BI).

→ Cloud & DevOps: Google Cloud, Azure, Docker – from architecture to deployment.

Over 20 projects, including for startups, SMEs, and corporations – also in regulated environments like BaFin and Healthcare.

At 2pi IT Solutions, a team stands behind me that scales as needed.
