Building a fintech app with Tailwind CSS? Let us review it.
Expert code review for fintech apps built with Tailwind CSS. We fix Tailwind CSS-specific security gaps, optimize performance, and handle deployment. From $19.
Common Tailwind CSS issues we find
Real problems from Tailwind CSS codebases we've reviewed.
Inconsistent spacing and sizing
AI tools use arbitrary values (px-[17px]) instead of Tailwind's spacing scale, creating visual inconsistency across the app.
Missing responsive breakpoints
Components designed for desktop only. Mobile layouts break or are unusable because responsive classes weren't added.
Oversized CSS bundle
Unused classes not purged, custom CSS duplicating Tailwind utilities, and unnecessary safelist entries bloating the stylesheet.
No design tokens in config
Colors, fonts, and spacing hardcoded in classes instead of defined in tailwind.config. Changes require find-and-replace across the entire codebase.
Fintech App challenges to solve
Key fintech app concerns that AI-generated code often misses.
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.
What we check
Key areas we review for Tailwind CSS fintech app projects.
Data encryption — field-level encryption for sensitive financial data
Transaction integrity — atomic operations, no partial state changes
Audit logging — immutable records of every financial action
Authentication — MFA, session management, account lockout policies
