What does “from $10,000” actually mean?Every engagement starts with a scoping call. “From” is the floor for a fully-instrumented, production-ready build — not a stripped-down prototype. Scope, integrations, and ongoing care determine the final number. We quote fixed-price, not hourly, so you are never watching a clock. What stack do you build on?Headless Next.js + TypeScript for web; Kotlin Multiplatform + Compose Multiplatform for mobile. All builds are AI-native — models integrated where they create real leverage, not bolted on as a talking point. Full GraphQL or REST APIs, deployed to Vercel or your own infrastructure. Can you build a mobile app or a multi-tenant SaaS?Yes — that is the Platform tier. Kotlin Multiplatform gives you a single shared business-logic codebase with native iOS and Android UIs. Multi-tenant SaaS architecture is a specialty, not an afterthought. Reach out for a scoping conversation. Who will I work with?Kevin Champlin leads every engagement directly — 28 years of hands-on engineering, no offshore hand-offs, no junior bait-and-switch. For larger builds, senior contractors are brought in under the same engineering standards.
