Im a Principal Product Designer with over 20 years of professional experience including 10+ years of product experience across agencies, startups, media, and game studios, and the last 4 years has been focused on building AI products.  
 
I strongly believe that great product design combines a user-centered approach with a strong and appealing visual language. Im a systems thinker with a strong technical background holding a degree in Computer Science. I am pragmatic in solving problems, empathetic to users, and skilled at communicating complex ideas effectively while pushing the boundaries of whats possible. 
 
Over the years, Ive built up hands-on design expertise, domain knowledge, and leadership skills. I enjoy driving product vision, shaping company-wide design strategy, mentoring senior designers, and helping teams solve complex challenges with clarity and creativity. 
 
Im passionate about designing intuitive, scalable products, working closely with product and engineering teams to turn ideas into impact.

Work Experience

Aug 2023 - Current

Principal Product Designer

Replica

At Replica, my work focuses on designing ethical, AI-powered tools for voice and creative media. User experiences span a suite of products centered on voice AI (TTS, STS, Voice FX), cloning, and real-time speech manipulation, built to support the workflows of game studios and content creators. Key contributions include the design and prototyping of: ✦ Voice Director – TTS generation with SSML support ✦ Voice Changer – Real-time speech-to-speech (STS) and FX ✦ Voice Lab – Voice blending for character creation ✦ Voice Clone – Custom voice cloning for creators ✦ SFX Generator – AI-generated sound effects via text prompts Design efforts also extend to AI-driven tools for 2D and 3D game asset generation, streamlining production and accelerating creative pipelines. A core part of the role includes leading the product’s digital transformation to the web, introducing a composable component architecture that enables faster iteration and more efficient collaboration across teams. The role bridges hands-on product design with broader product strategy—building scalable systems, aligning with engineering and AI teams, and shaping experiences that serve both user needs and business goals. Through a combination of design craft and strategic leadership, the work helps define the future of creative tooling—unlocking new storytelling possibilities through thoughtfully designed AI experiences.
