I'm building machine learning systems for mobile networks, network reliability, and time-series prediction.
What I'm looking for
I'm building machine learning systems at Beeline for mobile-network KPI analysis, anomaly detection, traffic forecasting, and packet-loss investigation. Using base-station and transport-network adjacency data, I help identify underlying causes and pinpoint problematic network hops.
Previously, I supported Beeline's IP Backbone research, migrating IP address management from Oracle to NetBox, parsing router configurations, and analyzing crash data. I used graph neural networks to identify weak infrastructure points, model crash propagation, and estimate device-crash probabilities up to a week ahead.
I've also worked on trading-bot tooling and Bayesian optimization at AIM Fund, improving backtesting time and results by 33%. My projects include LLM-based recommender-system benchmarking, time-series forecasting with RNNs and GNNs, and EEG/MEG classification using classical ML features.
