Hi, my name is

Marian Helcl Øverli.
I build intelligent systems.

Applied physicist from NTNU, Trondheim, and now diving deep into AI engineering. I'm building tools that can create real value while also having fun!

About Me

A bit about who I am and what I do.

I'm an aspiring AI engineer with a strong interest in machine learning, natural language processing, and computer vision. I enjoy turning ideas into working code and building end-to-end ML pipelines.

I'm constantly learning and experimenting with new architectures, frameworks, and techniques. My goal is to contribute to AI systems that solve real-world problems.

Masters in applied physics from NTNU, Trondheim, 5 years experience as an acoustic consultant. Am now all in on AI Engineering

Projects

Things I've built and experiments I've run.

Financial Risk Copilot training dashboard showing ROC curve, SHAP feature importance, and confusion matrix

Financial Risk Copilot

An AI-powered system that predicts corporate bankruptcy risk using XGBoost with SHAP explainability, RAG over 10-K filings, and a conversational chat agent that routes queries to the right tool automatically.

Python XGBoost LangChain SHAP Streamlit
Interactive Diary chat interface powered by Claude AI

Interactive Diary

A conversational journaling app where you chat with Claude about your day. It summarizes the conversation into structured diary entries with themes, mood, and patterns — saved to Notion.
