Omar Bouaziz

Founding ML Engineer · Poland · Remote

• Built and shipped SkinScan (skin-scan.ai), the AI skin-lesion screening product: lesions are pinned on a full-body map and re-photographed over time, and the model flags changes for review. Named a Top 20 semifinalist in Go Healthy with Taiwan 2026 out of 832 proposals from 62 countries.
• Unified fragmented clinical software into one workflow, eliminating system-switching and cutting doctors' time by 30%.
• Trained, fine-tuned, and deployed the image classification models behind SkinScan (PyTorch/ONNX) from data prep to checkpointing, with monitoring pipelines to keep them at clinical diagnostic standards; built the image documentation and lesion-tracking tools around them.
• Integrated voice and LLM features with role-based access controls and audit trails, expanding secure access to medical data for more accurate diagnostics.
• Designed and built the automated scoring pipeline for Bittensor Subnet 76, including benchmarking protocols and adversarial-defense mechanisms to secure the token-incentivized model-evaluation system against manipulation.
