During development we split tasks across Claude Code, Codex and Gemini, while design and final review stay with a human. That is how a small team ships fast.
How a project runs
One person from the first call to handover.
No handoffs between account managers and developers. The developer you talk to designs, builds, deploys and hands over the product.
- 01
Consultation and scope
We learn who uses the product and which features are essential, then define the first release and the quote. A written spec is not required.
- 02
Design and development
Screens, data, servers, payment and deployment are designed and built together. Progress is shared as links in one chat room.
- 03
Checkpoint
You see a working intermediate build and confirm the direction. We note what to change and continue to completion.
- 04
Completion and deployment
Deployed to your own domain, servers and payment accounts, with the settings needed for operation.
- 05
Handover and source delivery
The source repository, accounts and operations documents become yours. We also explain how to edit and run it yourself.
Payment terms
50% deposit · 30% at checkpoint · 20% at handover.
Three installments. Each one is paid after you have checked the result of that stage.
- 50%DepositOn contract · work begins
- 30%CheckpointAfter reviewing a working intermediate build
- 20%Handover · source deliveryBefore source code and accounts are delivered
- Quotes depend on product scope and situation. VAT is excluded.
- Third-party fees — domains, servers, payment providers, paid AI — are billed to your own accounts.
- Changes, additional development and maintenance after completion are agreed separately.
Handover
You get more than code.
A product lasts when the client can run it alone. So the handover includes:
Source code and accounts
Repository, domain, servers and payment accounts are transferred to you. No lock-in to kinoflare.
Security baseline
Authentication and permissions, secret separation, HTTPS and security headers applied, plus a checklist.
Deployment and operations docs
How to deploy, how the servers are set up, expected monthly cost and how it changes as usage grows.
Operating-cost optimization
Designed to use free and low-cost tiers first. This site and most of our references run that way.
Editing it yourself with AI
A guide and hands-on session for changing copy, screens and features with AI tools, so small edits never need a contractor.
FAQ
Before you hire us.
Can we talk without a written spec?
Yes. Knowing what you want to build is enough. Tell us who uses it and what it must do, and we define the core features and the first release together.
How is the quote decided?
By product scope — number of screens, members, payment, admin, AI and third-party integrations — and schedule. We send a quote after the scope is settled. VAT is excluded.
How is payment split?
50% deposit → 30% at checkpoint → 20% at handover and source delivery. Each installment follows your review of that stage.
What technology do you use?
Mostly SvelteKit, TypeScript, Cloudflare and PostgreSQL for web; Flutter or native for apps; Python and model APIs for AI. Other stacks are possible when your situation calls for it.
Can you build multilingual or overseas services?
Yes. Try Failing runs in seven languages and SIDF in five, with overseas payment such as PayPal. We have also delivered projects for companies in Australia and China.
Who owns the source code?
You do. At handover we transfer the repository and every account.
What if something breaks after completion?
You can still reach us on KakaoTalk after handover, and changes, additional development and maintenance can be arranged separately.
Can you do fields not in the references?
Beyond the public cases we have built several games, fortune-telling and dating services, crypto exchanges and an air-quality analysis system. We explain the range of experience in consultation.
