MOBILE + BACKEND · FINANCIAL APIS
Financial API workflows with traceable requests.
Built Flutter interfaces and supporting NestJS functionality for verification, consent, and balance workflows. The backend separates provider credentials from the client.
Workflow at a glance
- Mobile client
- Authenticated API
- Provider
- History
The problem
A financial API tool must distinguish a transport error from a provider business response, while handling uncertain submissions without accidentally repeating them.
What I built
- Built mobile interfaces and API integrations for verification, account-consent, and balance workflows.
- Built supporting backend functionality through an authenticated NestJS service.
- Worked across mobile and backend layers to connect provider workflows and request-history views.
Platform capabilities
Described at platform level, separately from my individual contributions above.
Durable request state
Persistent request tracking and duplicate-submission safeguards support reliable handling of incomplete and repeated requests.
Credentials behind the backend
Provider credentials remain server-side rather than being distributed with the client.
Failures that can be investigated
Sanitized history and separate transport/business-status handling make failed and incomplete requests traceable.
How this is supported
Source review supports the listed backend capabilities. My confirmed contribution spans mobile interfaces, integrations, and supporting backend functionality; advanced request safeguards are described at platform level.
This is company work at Finovel Fintech Private Limited. The source code, integrations, and customer data are private, so there is no public repository or screenshot for this project.
Takeaway
Mobile usability connected to backend-mediated integrations and explicit request-state handling.
