About Us
We are a technical team focused on app interface integration and authorization API connections, skilled in protocol analysis, API refactoring, and Open Data integration for financial and payments mobile apps. We support Android and iOS platforms and deliver runnable API source code, API documentation, and automated testing scripts according to client needs.
Compliance Commitment: All work is conducted under client authorization or based on publicly available/licensed APIs (Open Data / official APIs). We strictly follow privacy and legal requirements, and use neutral terms such as reverse engineering/data extraction where applicable to avoid risk-sensitive language.

Target App Integration Examples & Implementation Highlights
The following are interface implementation recommendations and deliverables tailored to the features of different apps (each project customized based on client authorization and the actual protocols of the target platforms):
- 22nd State Bank Mobile: Implement account login (multi-factor authentication), real-time balance and transaction history synchronization, electronic statement download; provide examples for secure session renewal and mobile push notification validation.
- CREDITAS Banking: Modeling interfaces for credit products (installments, mortgages), API for repayment plan calculations, standardized adaptation of credit card statements and credit limits, including compliant customer identity verification processes.
- Vista Mobile: Connect the session layer between mobile banking frontend and backend, transfer and beneficiary management interfaces, asynchronous notifications and callbacks (webhooks); provide performance and concurrency testing scripts.
- Cartão de crédito Carrefour: Credit card transaction parsing, installment payments API, promotions and rewards points inquiries, statement export (PDF/CSV) and reconciliation automation scripts.
- CSE Mobile App: Account management, expense payments, invoicing & reconciliation APIs for corporate/education scenarios; supports multi-role permissions and report export APIs.
- Moduit Advisor: Portfolio aggregation for investment-advisor apps, risk assessment questionnaire APIs, robo-advisory order placement and investment recommendation model encapsulation, including backtesting simulations and compliant logging export.
Deliverables
- Runnable sample code (Node.js / Python / Java) with deployment instructions
- Complete API documentation (OpenAPI/Swagger), Postman collections, and environment variable guidance
- Authentication workflows and security configuration documentation (OAuth2/JWT/TLS)
- Automated test scripts, sample data sets, and go-live testing plan
Pricing & Project Process
- Clear pricing: starting at $300, with sample deliverables provided first and payment upon acceptance.
- Process: Requirements confirmation → Authorization & compliance review → Protocol analysis → Interface implementation → Testing & documentation delivery → Go-live support.
- Guarantee: Work only with client authorization or when using publicly available APIs; NDA can be signed.
