Chicago, Illinois, United States
Summary
👤
Senior🎓
Top SchoolCrystal Contreras is a founder and ML engineer with eight years of full-stack and cloud systems experience who left AWS to build a stealth multimodal AI video-editing engine that auto-syncs clips to music using audio analysis, LLM-driven storyboarding, and vision models. She has production experience at scale from Amazon Firehose to GPU-optimized ML pipelines, plus published deep learning research on software-vulnerability classification (ACM, 2023). Comfortable across Python, Java, and modern cloud infrastructure, she designs robust, idempotent orchestration for long-running jobs and has reduced GPU memory usage by ~38% through systems-level optimizations. Based in Chicago, she blends research rigor with product-focused experimentation—structuring A/B-style model evaluations and qualitative error analysis—to turn creative workflows into reliable, seconds-long user experiences. An unexpected detail: she pairs technical work with discipline from jiu jitsu (blue belt), reflecting a methodical, iterative approach to tough engineering problems.
