My experience with Python , PyTorch, TensorFlow , SQL, NLP, and model evaluation fits the team’s work to keep digital spaces safe, welcoming, and supportive of creativity. In my current role, I build text-classification and ranking models for spam, harassment, and policy-evasion signals across about 18 million weekly records. I have created reproducible ML pipelines , validation checks, and monitoring views for precision, recall, class drift, review volume, and threshold changes. This work helps policy partners spot performance shifts and make sound review decisions. I bring practical experience connecting machine learning work with human review. I have built evaluation sets with policy specialists , documented model cards and known limitations, and created tools that record reviewer rationale and disagreement. I communicate results and residual risks clearly to engineering, data, policy, and product partners. LumenWave Audio interests me since this role combines trust and safety with responsible GenAI use. I would be glad to explore retrieval, structured prompts, guardrails, and multi-step workflows that help policy specialists work more efficiently without losing transparency or auditability. The chance to learn from experienced practitioners and support a safer digital community is especially appealing. Thank you for considering my application. I would welcome the opportunity to discuss how my machine learning and trust and safety experience could support LumenWave Audio’s team.
