Goldman Sachs Engineering Challenge

1st place at the 18-hour Goldman Sachs Engineering Challenge at Warsaw Spire. We built HackathonHub — a platform for running data-science competitions end to end: Docker-isolated automatic scoring, live leaderboards, team management with invites and surveys, a judge dashboard, and 2FA role-based access. It supports classification, regression, NLP, computer-vision and time-series challenges, with a pre-built ML sandbox (TensorFlow, PyTorch, XGBoost).
