AI you can
put to the test.

I build and test AI systems, from document retrieval to image recognition. I show what works, where a system fails and what to improve, bringing experience from sport and leading teams to the way I work.

About

I build and evaluate AI systems that can be checked.

Three-quarter portrait of Mateusz Więcek

I am an MSc Artificial Intelligence and Applications candidate at the University of Strathclyde. I produce evidence-based assessments of models and systems using explicit metrics, tests, error analysis, safety checks and documented assumptions.

  • Machine learning
  • RAG & LLMs
  • Computer vision

How I can help

From a question to evidence.

Looking for help with an AI project or someone to join your team? These are the problems I work on.

01

AI evaluation

Model comparisons, answer-quality tests and error analysis. The outcome: a clear view of what a system can and cannot do.

02

RAG and machine learning

Prototypes for document retrieval, classification and prediction. The outcome: a reproducible experiment with code and metrics.

03

Technology for people

I combine technical work with experience leading sports groups. I explain complex ideas clearly and turn them into practical next steps.

Evidence over promises

Results you can inspect.

Selected metrics from academic projects. Every number has a defined dataset, evaluation method and limitations.

How I work

Question. Experiment. Evidence.

I do not treat a model score as decoration. First I define what we are really measuring, then I build a repeatable experiment and present the result together with its limitations.

Recall@3 · Clinical RAG

retrieval over a synthetic EHR dataset

Method and limitation +

How it was tested: Qrels and explicit P@3, R@3 and MRR for patient-specific retrieval.

Limit: This is not 100% answer quality or clinical effectiveness. The data is synthetic.

0288.62%

Sign Language MNIST

aligned multiclass accuracy

Method and limitation +

How it was tested: A feed-forward network built in NumPy, with regularisation, early stopping and error analysis.

Limit: A 28×28 image benchmark; it does not measure real-world camera-based gesture recognition.

Project source
036.52657

Spotify popularity RMSE

reported regression-model error

Method and limitation +

How it was tested: CatBoost, baselines, feature engineering, validation, diagnostic figures and tests.

Limit: The result depends on the dataset and target scale; it is not a recommender-system score.

GA strategy · out-of-sample

with 9.99% maximum drawdown

Method and limitation +

How it was tested: Chronological train/test evaluation, transaction costs and several comparison baselines.

Limit: A historical experiment, not a forecast of future returns or investment advice.

Experience

Work, projects and experiences I contribute to.

From people and communication, through demanding operations, to reproducible AI systems — each experience reinforces responsibility for the outcome.

Beyond the screen

Technology is only part of the story.

Sport is not an accessory to my work. Physical-education training, football, freestyle football and leading groups of young people have taught me focus, calm and responsibility for others — the same qualities I bring to technology.

01

Sport

Movement, focus and consistency.

02

People

Leading groups and creating a positive atmosphere.

03

Curiosity

Connecting distant fields into new ideas.
