About
I am a recent ICT engineering graduate from JAMK University of Applied Sciences, specialized in Data Analytics and AI, with a weighted grade average of 4.71 / 5.0 and top grades in Deep Learning, Machine Learning, Data Preprocessing and Computational Algorithms.
My work spans the full lifecycle: collecting and cleaning data, building and evaluating models, and shipping them as production services with FastAPI, Docker and Hugging Face Spaces. My bachelor's thesis delivered a deployed bilingual course similarity system used in a real university project.
Primary focus: Data Science, Data Engineering, AI, Machine Learning and Deep Learning. Secondary: full stack development with Node.js, Express, PostgreSQL and React.

Multilingual Sentence Embeddings for Bilingual Course Similarity
Thesis
Finnish and English Course Similarity
Built for the LuoVuutta project: an evaluation of multilingual sentence embedding models for detecting similar course descriptions across Finnish and English in Finnish higher education. Five models were compared across 30 configurations. LaBSE performed best and now powers a production FastAPI service with a live public demo on Hugging Face Spaces.
