Description

I build data infrastructure and user interfaces that work

in production.

Over the past 3+ years I've been the engineer behind

multiple projects at AI Forensics, a European non-profit

investigating algorithmic transparency including LOT1,

a European Commission-funded social media data collection

pipeline covering Social Media monitoring at scale.

I work across the full stack:

→ Data pipelines and backend architecture (Python, FastAPI,

PostgreSQL, SQLAlchemy)

→ React/Next.js/TypeScript interfaces for data analysis

and monitoring

→ API integrations, web scraping, CI/CD

→ UX/UI design for data-heavy tools

I've built systems from scratch, worked autonomously, and

delivered on tight deadlines for institutional clients

including the European Commission.

I'm currently open to freelance contracts across Europe —

remote or hybrid.
