Hi! I'm starting a fintech mvp, can we close it in 8 weeks?
Hello! 8 weeks is viable for a focused mvp: onboarding, basic KYC, wallet and simple payments. Want to see a roadmap example?
Yes, and how much does it cost?
Every project is different — I'd rather talk before quoting a number. Send me an email at contato@ryutac.com.

04 · Manifesto

Well-built software is, above all, a decision.

  1. 01Seniority isn't expensive — it's what makes everything else cheap.
  2. 02Good code is what the next Dev understands without calling you.
  3. 03No empty presentations. No junior billed as a senior.
  4. 04The code is yours. Always. No lock-in, no hostages.
  5. 05A realistic deadline is a kept deadline — not a broken promise.
