I will review and design your modern web app architecture
Fumiaki T
Über diesen Service
Design a modern web app architecture that is practical, secure, and ready to ship.
I will review your current stack or turn your product idea into a clear technical blueprint using Next.js, Cloudflare, Supabase or Turso, Resend, and other fit-for-purpose services.
You can receive a current architecture review, prioritized risk analysis, recommended frontend and backend services, database and authentication guidance, data-flow planning, security and reliability considerations, free-tier and operating-cost guidance, deployment strategy, and a phased implementation roadmap.
This is ideal for founders, SaaS teams, and vibe-coded app owners who want to avoid expensive rewrites and choose the right services before building further.
I am a Japan-based engineer with 20+ years in production web development. You get practical recommendations instead of unnecessary complexity, clear tradeoffs around cost, speed, security, and scale, and a personally reviewed written handoff your developer can act on.
Send your product summary, current stack, expected users, integrations, and biggest concerns before ordering. I will recommend the smallest useful package.

FAQ
Do you need access to my Stripe account?
I need test-mode access or a safe collaboration method plus the relevant repository. Keep secret keys in environment variables and never paste them into a public message.
Are Stripe fees included?
No. Stripe processing fees and any account charges are paid directly by you. This Gig covers development, configuration, testing, and handoff.
Can you add subscriptions and Customer Portal?
Yes. The Standard package is designed for subscriptions, Customer Portal, and secure webhook handling for one product or pricing structure.
Can you work with Supabase authentication?
Yes. I can connect Stripe customers and subscriptions to Supabase users and update roles or entitlements from verified webhook events.
What should I send before ordering?
Send your stack, repository or preview, authentication provider, Stripe products or pricing plan, and the exact payment flow. I will confirm the scope first.
