Built a fintech app with Augment Code?
We'll make it production-ready.
Financial apps handle the most sensitive data there is — bank accounts, transactions, and personal financial information. A single security flaw can mean stolen funds, regulatory penalties, or permanent loss of user trust. AI tools can prototype a budgeting dashboard or invoicing system quickly, but the compliance, encryption, and audit requirements for financial software are far beyond what any AI tool generates out of the box.
Fintech App challenges in Augment Code apps
Building a fintech app with Augment Code is a great start — but these challenges need attention before launch.
Data encryption and storage
Financial data must be encrypted at rest and in transit. Account numbers, transaction histories, and personally identifiable financial information need field-level encryption, not just HTTPS. AI tools store financial data in plain text in the database, which is a compliance violation waiting to happen.
Transaction integrity
Financial transactions must be atomic — money debited from one account must be credited to another, with no in-between state where it disappears. AI-generated code doesn't use database transactions, meaning a server crash mid-operation can leave accounts in an inconsistent state.
Audit trail and compliance
Every financial action needs an immutable log — who initiated it, when, what changed, and what the balances were before and after. Regulators require this. AI tools don't generate audit logging, and retrofitting it into an existing codebase is tedious but essential.
Third-party financial API integration
Connecting to Plaid, Stripe, or banking APIs requires handling OAuth flows, webhook verification, idempotency keys, and retry logic for failed calls. AI tools generate the initial API call but miss the error handling and reliability patterns these services require.
Authentication and fraud prevention
Financial apps need multi-factor authentication, session timeout policies, device fingerprinting, and suspicious activity detection. Basic email/password auth from AI tools is nowhere near sufficient for an app that touches people's money.
Number precision and currency handling
JavaScript floating-point math causes rounding errors with money — $0.1 + $0.2 !== $0.3. AI tools use standard floats for currency calculations, which leads to penny discrepancies that compound over time and break reconciliation.
Regulatory awareness
Depending on what your app does, you may need to comply with PCI DSS, SOC 2, KYC/AML requirements, or state money transmitter regulations. AI tools have no awareness of these requirements, and non-compliance can result in fines or forced shutdowns.
What we check in your Augment Code fintech app
Common Augment Code issues we fix
Beyond fintech app-specific issues, these are Augment Code patterns we commonly fix.
Cross-module dependency suggestions that violate architectural boundaries
Augment Code's broad codebase awareness can lead it to suggest importing modules or calling functions across architectural layers that should be decoupled — for example, suggesting a UI component directly call a database utility instead of going through a service layer.
Security patterns from older parts of the codebase propagated to new code
When the codebase contains legacy code with deprecated or insecure patterns, Augment Code learns from those patterns and may suggest them in new code, spreading outdated authentication, validation, or encryption approaches.
Suggestions mirror existing buggy patterns rather than fixing the root cause
If the codebase has a consistent bug pattern — such as a missing null check in multiple similar functions — Augment Code will replicate that bug in new suggestions because it learns from existing code rather than reasoning about correctness.
Monorepo package boundary confusion leads to circular import suggestions
In large monorepos with shared packages, Augment Code sometimes suggests imports that create circular dependencies between packages, which can cause build failures or subtle runtime initialization order bugs.

Frequently asked questions
Can I build a fintech app with Augment Code?
Augment Code is a great starting point for a fintech app. It handles the initial scaffolding well, but fintech apps have specific requirements — data encryption and storage and transaction integrity — that need professional attention before launch.
What issues does Augment Code leave in fintech apps?
Common issues include: cross-module dependency suggestions that violate architectural boundaries, security patterns from older parts of the codebase propagated to new code, suggestions mirror existing buggy patterns rather than fixing the root cause. For a fintech app specifically, these issues are compounded by the need for data encryption and storage.
How do I make my Augment Code fintech app production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Augment Code-built fintech apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Augment Code-built fintech app?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger fintech app projects, we provide a custom fixed quote after the audit — no hourly billing.
