What we do

From your idea to a finished product.

We build our own apps and take on client projects across iOS, AI, and the web. The same team handles design, engineering, and launch, so your product ships with real users, real billing, and privacy we stand behind.

Native iOS

iPhone apps built in SwiftUI with StoreKit 2 subscriptions, Face ID, and on-device data protection. Two are live on the App Store.

Applied AI

Production systems on Claude, OpenAI, and fal.ai: reflection engines, multi-agent review panels, moderation, and image generation.

Web and SaaS

React and Astro front ends, serverless back ends, Stripe billing, and pricing that stays honest about real cost.

Privacy first

Encryption in transit and at rest, data that stays on device when it can, and a firm rule: no model trains on user data.

Technology

The stack behind the products.

One team works across the whole stack, from Swift on the device to the model calls, billing, and infrastructure that keep an app running.

Cost-aware AI

Model routing by task and pay-per-use pricing, so the unit economics hold as usage grows.

Defense in depth

Input validation at every boundary, prompt-injection defenses, rate limiting, and idempotent billing.

Ship in green phases

Large work lands in small phases that each build, deploy, and verify before the next begins.

About

We ship our own apps. And yours.

Neon Peach, LLC is an AI-driven product studio founded in 2025 and based in Atlanta, Georgia. We build cloud-native, full-stack web and mobile apps and the automation behind them, for our own catalog and for the clients we partner with.

Shipping our own products keeps us honest. We know what it takes to carry an app from idea to the App Store and keep it running, and we bring that same ownership to your project. Your vision, built like it is our own.

Founder

Ray W. Shiraishi, Ph.D.

Mathematical statistician · Founder

Ray founded Neon Peach to build software end to end, both the studio's own products and the work it takes on for clients. He architects and ships across the stack, from Next.js and Node.js front ends to Firebase back ends, REST APIs, and LLM integrations.

Much of the work is agentic: multi-step reasoning, tool use, and decision logic, held together by prompt-engineering frameworks that keep outputs consistent and structured. As a mathematical statistician with more than 70 peer-reviewed publications, he brings that same rigor to how the products are measured and validated.

Areas of focus

  • Full-stack, cloud-native architecture
  • Agentic AI workflows
  • Prompt-engineering frameworks
  • Data pipelines & automation
  • Technical SEO
  • Security & secure API design
