I build production web platforms with frontend excellence, full-stack depth, and AI-augmented discipline.
I'm Brandon Perfetti, a Senior Frontend Engineer in Orange County, California. For 10+ years I've shipped SaaS platforms, data integrations, and delivery programs - today I lead frontend for a multi-tenant real-estate platform and run AI-augmented engineering as a daily practice.
Frontend at fleet scale
Most of my work happens at fleet scale: one shared React and TypeScript package behind five brokerage sites and a portal, each with its own headless CMS. Working that way changes what counts as a good decision, because a component choice stops being a component choice when five tenants inherit it. The role runs well past UI: technical SEO, privacy and consent, analytics integrity, and fleet-wide test infrastructure.
AI-augmented engineering, run with discipline
I run most delivery through parallel agent lanes, under a written evidence discipline that separates measured fact from inference. The agents are the fast part; the specification that precedes them and the review pass that follows are what make the work correct. How I work sets out the pipeline, the four rules that keep it accountable, and an audit of it by one of my own agents.
Full-stack foundations
A decade of data integrations built the depth: platforms administering 250+ MLS feeds and 10M+ records, SSO across 100+ third-party systems, and documentation that turns tribal knowledge into self-service.
Delivery you can plan around
I work across the full lifecycle with product, design, and client teams - clear priorities, realistic commitments, and the working agreements that keep multi-repo, multi-agent programs coherent.
Where I'm pointed next
More of the second thing: building the tools and the guardrails that let a team move at agent speed without losing the plot.
