Who We Are
We are a technology team focused on app interface integration and authorized API integration, with long-term service in finance, payments, accounting, and investment apps. We provide protocol analysis, interface refactoring, Open Data / third-party API integration, and automation scripting with complete API documentation delivery.
Compliance Commitment: All projects are based on client authorization or on publicly available/licensed APIs (Open Data / Authorized interfaces). We comply with local laws and privacy protections. We avoid improper terms and use compliant phrasing such as “protocol analysis / reverse engineering (within authorized scope).”

- OpenAPI/Swagger docs + Postman collections (including Authorization/Headers examples)
- Data model documentation, field mapping tables, and reconciliation policy documents
- Test cases and automated tests (unit + integration)
- NDA and compliance notes (as needed), plus deployment support and bug-fix windows
Technology & Security
- Transport security: TLS 1.2+/HTTPS, certificate validation, HSTS recommendations
- Authentication & authorization: OAuth2, OpenID Connect, JWT, short-lived tokens with refresh
- Data protection: encrypted storage of sensitive data (AES), field-level masking, principle of least privilege
- Logging & auditing: structured logs, request tracing, compliance retention policies
Pricing & Service Process
- Starting at $300, with a pay-after-delivery model upon customer satisfaction
- Process: requirements confirmation → contract analysis → prototype implementation → documentation delivery → testing and go-live support
- Delivery timeline depends on complexity; typical first version for standard interfaces is 5–10 business days
FAQ
What information does the client need to provide?
Target app name and concrete requirements/scenarios, authorization credentials or API access rights (where applicable), and whether localization (language/regulatory) support is needed.
Do you support multilingual and local regulatory compliance?
Yes. We can provide localized docs and field mappings in Chinese/English/Russian, and adjust data retention and encryption policies within compliance.
How is deployment handled after delivery?
We deliver runnable code and documentation and can assist with deploying to the client’s backend/cloud environment, with validation and go-live support.
