Ray Festa
Product designer who builds. Six years designing how people supervise AI agents inside AWS data infrastructure, now shipping production systems end to end.
Experience
Founder, RF Digital
2026 - present- AI systems consultancy: client-facing intake systems, workflow automation, and oversight layers that decide what an agent finishes alone and what reaches a person.
- Design, build, and deploy end to end, from the interface through the agent architecture to the evaluation loop that grades its output.
Senior Product Designer, Databases, Amazon Web Services
2020 - 2026- Designed management and oversight surfaces for managed database and data-infrastructure products used by Fortune 500 companies and government agencies.
- Visual data model builder for time-series schemas: 93% adoption at launch, and setup time compressed from roughly 90 days to hours by meeting users inside their existing SQL mental model.
- Conversational analytics tool rebuilt as a progressive dialogue: query accuracy went from 20% to 90% after the redesign, with prompt tuning done alongside the engineering team.
- Moved from configuration consoles to agentic oversight: the surfaces where people supervise AI agents, set thresholds, and review what the system did before accepting it.
Product Designer, PayPal · Atlassian
2010s- A decade of product design across B2B and consumer products before specializing in enterprise data infrastructure.
Selected work
Alpine Velo
AI cycling coach, live on the App Store. Designed and built solo: the iOS app, the coaching agent, the training science it reasons with, the brand and visual system, and a self-grading loop that scores the coach's answers and rolls back changes that make it worse.
AI Finance Dashboard
Production-ready UI for AI finance agents. Nine pages and a documented design system, built through Figma, v0, Claude Code, and Vercel.
Capium
Personal finance app, designed but never shipped. Kept as a craft piece: the interface argument for showing a user what is true before telling them what to do.
