About
What started as a way to explore data science and AI outside the classroom has grown into a collection of projects that showcase what can be built when enjoyment and curiosity meet determination.
With the goal of continuous learning and fun, during our studies back in april 2024 a friend and I co-founded Nordic Raven Solutions, a data consultancy. Honorary collaborations include Paper Check and my University Dormitory.
Since then I have graduated with my Masters in Business Intelligence from Aarhus University (Oct. 2025), and built a portfolio to showcase my determination to apply my skills outside of the classroom too.
What I love doing

My Latest Projects
Aarhus RE Scanner
Automated Property Valuation, Benchmarked Against the Government
Solo-built automated valuation model for Aarhus residential real estate — a 5-model stacking ensemble on a hedonic log-price target, validated on a strict temporal holdout. Benchmarked against the accuracy figures from Denmark's own tax-authority model-development process (2014 Engberg-udvalget, 2016 ICE refinement): this model's house predictions land within ±20% of the real sale price 81.3% of the time, beating every documented iteration of the government's own development-stage numbers.
DK1/DK2 Power Price Forecasting
Day-Ahead Forecasting + Backtested Divergence Strategy
Built a day-ahead electricity price forecasting pipeline for the Danish power market using Energinet's free API, with walk-forward (not shuffled) cross-validation and leakage-checked features (55% RMSE reduction over seasonal-naive). Extended it into a backtested day-ahead-vs-imbalance-price trading strategy: an initial honest negative result led to richer regulation-state features that turned into a real, statistically significant edge, stress-tested with a blind holdout, Combinatorial Purged CV, tail-risk/Extreme Value Theory analysis, and cross-zone replication (DK1 + DK2). Full reasoning, including the negative results and corrections along the way, in the notebooks on GitHub.
AI Job Search & Career Toolkit
From Daily Scanning to Tailored Applications to Interview Prep
An end-to-end system that scans 8 job portals across 5 countries daily, mines years of old CVs into one fact-checked master profile, drafts tailored applications grounded strictly in it, preps for the resulting interviews, and ranks the highest-ROI way to spend spare time based on what employers are actually asking for. Built for real, ongoing use — including a full reliability pass after a genuine production backlog.
House Prices Prediction
Real Estate Economics Meets Machine Learning
Achieved top 8.1% performance (rank 476/5,887) in a Kaggle competition by combining hedonic pricing theory with modern ML techniques. Built an 8-model hybrid ensemble with 2-level stacking, demonstrating how domain knowledge guides feature engineering.
CodePractice.AI
Full-Stack AI-Powered Data Tutoring Platform
Built a mobile-first application using Gemini 1.5 to provide intelligent, real-time feedback on user-submitted Python and SQL code. Enables full code execution in the browser without backend dependencies.
AI News Digest
Multi-Agent News Curation System
Developed a multi-agent system (ReACT/RAG) for automated, quality-scored curation of AI research news, complete with LangSmith observability. Features RAG-based deduplication, ReACT agents with tool use, and weekly themed execution.
Ejendomsopslag
Real-Time Danish Property Data Enrichment
Built a real-time property lookup tool that enriches any Danish address with data from five government and public sources — BBR building records, historical sale prices, and energy certificates — including reverse-engineering two undocumented APIs where no official access existed. Deployed with full test coverage, structured logging, and GraphQL/REST integration against Denmark's national data-distribution platform.
FinSight
Business Intelligence & ETL Architecture
Created a robust ETL pipeline that extracts, normalizes, and validates financial facts (XBRL) from thousands of SEC/ESEF filings into a PostgreSQL warehouse. Interactive demo enables analysis of any publicly listed company.
Novo Nordisk Analysis
Financial & Competitive Analysis
Strategic analysis of Novo Nordisk with comprehensive financial metrics, peer comparison, and 5-year trend analysis. Dashboard showcases market positioning, financial fundamentals, R&D efficiency, and innovation returns.
CurRag
RAG System for University Notes
Built a Retrieval-Augmented Generation system for querying university lecture notes using LangChain, ChromaDB, and OpenAI. Features semantic search with natural language queries and a Streamlit web interface.
