Athanasios Tasis, Computer Engineering Student
About
I care about systems that can be tested, measured and explained.
I'm a final-year Computer Engineering & Informatics student at the University of Patras, focused on data, machine learning and backend development. Recently I worked as a data-engineering intern with the ALICE experiment at GSI / CERN, using large detector datasets and production HPC workflows.
My projects include a distributed hash-table simulation, a TF-IDF search engine with an evaluation pipeline, time-series forecasting work, and smaller experiments around spatial indexing, databases and networks. I mostly write Python and C/C++, with scikit-learn, NumPy and Pandas on the data-heavy side.
I'm looking for a graduate or junior role in backend, data or ML where I can learn from strong engineers and work on real problems. If that sounds like your team, feel free to reach out.
