Rockstar🎓
Top SchoolNick Peñaranda is a Staff Software Engineer with 14 years of hands-on experience building everything from embedded Linux devices and mobile apps to GraphQL-backed web platforms and machine learning developer tools. Currently at Weights & Biases, he contributes to backend systems powering ML workflows, including improving artifact uploads and launch APIs for a widely used AI dev platform. Previously at Credit Karma he led design and implementation of GraphQL federation and consumer-facing dashboard features, demonstrating a knack for decomposing monoliths into scalable microservices. His background blends rigorous human-factors research and a near-PhD level of academic training with practical engineering, giving him a data-driven approach to product and system design. A self-taught programmer with avionics maintenance experience in the Marine Corps, he brings unusual breadth across low-level embedded systems, cloud APIs, and user-facing products. He’s known for quickly learning new stacks and shipping robust, production-grade features that bridge research, hardware, and large-scale web services.
