They need a system that holds up with real users, real data, and real revenue from day one. We work architecture-first: full system design before a line of code ships. We move fast using AI-assisted development (Cursor, Claude), without cutting corners on what happens after launch. Real-World Examples We also built a multi-tenant booking and invoicing platform for a home-services client, handling scheduling, multi-tenant data isolation, and automated billing in active production. ➤ Best Fit For → Founders who need a working MVP, not a spec doc → Startups building AI-powered products who need a technical partner that moves fast → Businesses needing custom internal software — booking, invoicing, multi-tenant client systems → Teams that've been burned by slow agencies or all-talk dev shops → Anyone needing an AI sales agent that books appointments and closes ➤ Tech Stack → Next.js • React • Node.js • TypeScript • PostgreSQL • Prisma • Supabase • Stripe • OpenAI API • Claude API • LiveKit • Restack • Vercel ➤ 𝐁𝐮𝐢𝐥𝐝 𝐀𝐮𝐝𝐢𝐭 Send us your idea, unfinished MVP, or existing system.
