Rosier is a Senior Software Engineer based in the San Francisco Bay Area with nine years of professional experience and a seven-year focus on AI engineering and distributed systems. He has driven end-to-end delivery of scalable, serverless and microservice architectures at Adobe, building high-performance APIs, ML-driven analytics, and AI Agents that operate at enterprise scale with millions of requests. Comfortable across the full stack, he’s led frontend rewrites, backend optimizations, and data-driven tooling that ties code changes to business metrics and system degradations. Early work at Disney and startups produced automated data augmentation, model candidate selection, and computer-vision systems for robotics and defect detection—demonstrating a pattern of turning research into production-ready systems. Now at Blok, he continues to combine ML, systems engineering, and pragmatic product thinking to deliver reliability and low-latency experiences. An unexpected throughline: he consistently builds tooling that both scales traffic and surfaces actionable insights, not just models.
