Who We Are
We are a technology team focused on app interfaces and authorization API integration, with years of hands-on experience in mobile apps and fintech. We offer a one-stop delivery—from protocol analysis and API refactoring to Open Data integration and third-party service connections—and provide ongoing maintenance and upgrades after project delivery.
Compliance Commitment: All work is conducted based on client authorization or publicly available/licensed APIs (Open Data / Authorized APIs), in accordance with local laws and privacy protections. When necessary, we may use reverse engineering (as permitted by law) to achieve compatibility, but we do not engage in illegal or unauthorized data collection activities.
Core Capabilities
- Multi-domain coverage: crypto wallets, stock analysis tools, traditional banking and digital wallets
- Authentication & security: OAuth2, JWT, HTTPS/TLS, two-factor authentication, KYC/AML considerations
- Deliverables: runnable samples (Node.js / Python / Java), Postman collections, OpenAPI/Swagger docs
- Automation: periodic data harvesting, FX/market data synchronization, webhook/event-driven processing
- Compliance & privacy: NDA support, data minimization, and legitimate authorization workflows
Target App Examples and Implementation Highlights
The following are representative features and implementation highlights based on the target apps you provided, all assuming compliant authorization.
- Simply Wall St: Stock Analysis [com.simplywallst.app]: Aggregates global financial and valuation data, offering portfolio sync, watchlist import, historical price backtesting, and chart data APIs. Possibilities include stock screening API, financial metric extraction, and webhook-based push notification integration.
- MS Comptes Bancaires Mobile 12: Multi-account aggregation and transaction detail scraping, supporting semantic categorization, bill exports (CSV/OFX), and periodic reconciliation scripts. Implements secure login (OAuth/Token rotation) and session management strategies.

FAQ
How do you ensure compliance?
We work only within client authorization, publicly available APIs, or interfaces with authorized scope; for reverse-engineering scenarios we assess legality and risk and propose alternatives to ensure compliance.
Is localization supported (languages/currencies/regulatory rules)?
Yes. We can tailor for multi-language interfaces, different currencies, and regional regulatory requirements (e.g., KYC/AML).
Do you provide maintenance after delivery?
Yes, paid maintenance and version upgrades including adapting to API changes, monitoring alerts, and long-term support.
