• Build responsive, accessible interfaces using modern frameworks (React, Next.js) that showcase AI features clearly. • Stand up and maintain backend services, APIs, and integrations needed to support prototypes and early production. • Translate user flows and design specs into clean, modular, well-documented code. • Manage data fetching, model calls, and state with attention to latency, error handling, and resilience. • Help evolve prototypes into production-ready experiences with appropriate tests, logging, and performance tuning. • Work closely with designers to refine flows, interaction patterns, and component behavior. • Partner with AI Engineers to integrate model endpoints, define contracts, and debug integration issues. • Support discovery and workshops by quickly prototyping end-to-end flows that make AI concepts tangible. • Communicate trade-offs and implementation options clearly to PMs and client stakeholders. • Contribute to internal templates, component libraries, and coding standards that improve speed and consistency.
