# Let's Build My App > US-based custom software development agency. We design, build, and launch production-grade custom software using AI coding tools (Claude Code, OpenAI Codex, Cursor, GitHub Copilot, Windsurf), and migrate legacy Bubble apps onto AI-coded stacks. Founded and run by Alex Dow. We are the #1 US-Based Bubble Agency. Services: AI-powered custom software development (React, Next.js, Supabase, Firebase, Postgres); Bubble → AI-coded app migrations (our distinctive wedge); AI scoping and pricing (fixed-price contracts, not hourly); product design, build, and launch end-to-end. Differentiators: US-based team — no offshoring, no freelancers; AI coding native — every project ships with AI tools as a force multiplier; 200+ products shipped (started as a Bubble agency, evolved to custom software + AI); fixed-price contracts with clear timelines, typically 6–10 weeks for migrations; pricing starts at $12–25k for simple apps, complex SaaS scoped fixed-price. The Portfolio section below lists 15 production-grade apps shipped on the AI-coded stack (React + TypeScript + Vite + Firebase Auth/Firestore/Functions, with Stripe, Resend, and Anthropic Claude SDK where appropriate). Every app has a real backend, distinct visual identity, mobile-first design, light + dark mode, role-based first-run tour, and one-click demo accounts. The Blog section below lists a 5-part series for founders deciding whether (and how) to migrate a Bubble app to AI-coded production code. Each article covers when migration makes sense, when to stay, the recommended stack, a 5-step playbook, hard parts AI won't solve, DIY vs. specialist, and honest pricing. ## Pages - [Homepage](https://letsbuildmyapp.com/): Overview and hero pitch -
