Your fintech deserves
a CTO review.
9 expert lenses. Severity-rated findings. File-level citations. Built by a CTO who's led regulated financial groups and served as Distinguished Engineer at tier-1 banks.
Your code review isn't enough.
Standard tools and processes leave critical gaps in fintech codebases.
Generic tools miss fintech risks
SonarQube catches bugs. It doesn't catch regulatory gaps, compliance drift, or that your "buyback" button has no buyback code behind it.
Fractional CTOs cost £10K+/month
And they still can't review every commit. You need expert-grade assessment without the full-time cost.
Your investors will ask
Due diligence, security audits, regulatory readiness. Better to find the gaps yourself than have them found for you.
9 lenses. Zero blind spots.
Every review applies all 9 analytical lenses systematically. Each finding is severity-rated and cited to the exact file and line.
Security Posture
Vulnerabilities, secrets, auth, data protection, supply chain
Architecture
Layering, coupling, separation of concerns, patterns
Scalability
Bottlenecks, statelessness, caching, queuing
Cloud Independence
Vendor lock-in, abstraction layers, multi-cloud readiness
Regulatory & Compliance
KYC/AML, data protection, jurisdiction-specific gaps
Test Coverage
Unit, integration, E2E, BDD, quality gaps
Operating Costs
Infrastructure, dependencies, scaling cost curves
Speed to Market
What ships now vs what blocks launch
Trust Gaps
Where promises diverge from technical reality
From repo to report in minutes.
Three steps. No procurement cycle. No 6-week engagement.

# Executive Summary
This codebase presents 3 critical and 7 high-severity findings across security, compliance, and architecture. The payment processing flow lacks idempotency keys, creating a double-charge risk. No KYC/AML verification exists despite the app accepting payments in 4 jurisdictions. The "instant settlement" claim in the UI has no corresponding implementation in the backend.
# Security Findings
| Severity | Finding | Location | Impact |
|---|---|---|---|
| Critical | API keys hardcoded in source | src/config/stripe.ts:14 | Full payment system compromise |
| Critical | No rate limiting on auth endpoints | src/api/auth.ts:42 | Credential stuffing vulnerability |
| High | JWT tokens never expire | src/middleware/auth.ts:8 | Persistent session hijacking |
# Architecture Assessment
The monolithic Express.js backend handles payment processing, user management, and notification dispatch in a single process. Database queries use raw SQL strings without parameterisation, creating injection vectors at 14 locations...

Built by a CTO who's been in the hot seat.
I'm Fuzz (Farzad Pezeshkpour). I've spent 25+ years building and reviewing systems across financial services, crypto custody, defence, and real-time systems. I've sat in the regulator meetings. I've done the due diligence reviews. I've been the CTO who had to explain the security incident to the board.
FuzzCTO captures that experience in an AI-powered tool that delivers the same rigorous assessment I'd do myself, at a fraction of the time and cost. And when the findings need a human conversation, I'm here.
Standards fluency
Every review is informed by deep knowledge of the regulatory landscape.
"I've reviewed hundreds of fintech codebases. The same patterns keep appearing => hardcoded secrets, missing idempotency, compliance gaps nobody noticed until the regulator did. FuzzCTO catches these before they become expensive."
