Perguntas frequentes
What is your hourly rate?
My standard rate is $150/hr (direct hire, no middleman). Project minimums typically run $5-10k for prototypes, $15k for MVPs/production builds. Contact me for a quote.
Do you work on fixed-price projects or only hourly?
Hourly. Hourly is best for ongoing work, audits, or undefined scope.
What kind of apps do you build?
iOS (SwiftUI), Android (Kotlin), cross-platform (React Native), web (React/Next.js), backend (Firebase, Azure, AWS), AR/VR (Unity), and integrations (Stripe, auth, real-time sync).
How long does a typical MVP take?
12–24 weeks for a production-grade MVP (depending on scope). I focus on clean, scalable code so you avoid expensive rewrites later.
Can you help with existing code (tech debt, refactoring)?
Yes - I specialize in vibe-code cleanup, performance optimization, and production hardening for apps built by junior teams or AI tools.
What’s your availability?
I typically take on 1–2 new clients per quarter. Message me on Fiverr to check current slots.
