BankSmyth
Case Study Summary
Client Problem
Non-technical founders had built a fintech platform through vibe-coding (AI-assisted development) but had no way to evaluate whether the architecture was sound, secure, or ready for launch.
My Role
Fractional CTO (hands-on) — full architecture review, critical fixes, long-term strategy, tech stack improvements, release preparation
Result
Transformed a fragile vibe-coded prototype into a production-ready fintech platform. Fixed critical issues, built a long-term strategy, and delivered a team fully ready for marketing and sales.
Relevant For
Fintech startups, post-vibe-coding rescue, pre-launch technical readiness, non-technical founders
BankSmyth is a fintech platform that I joined as a fractional CTO after the non-technical founders had built an initial version through vibe-coding (AI-assisted development without deep technical oversight).
Role: Fractional CTO (hands-on)
Stage: Post-vibe-coding rescue → Production-ready release
What I Found
- Critical architectural issues that would have caused failures at scale
- Security vulnerabilities in the financial data handling layer
- Technical debt from AI-generated code that lacked proper error handling, testing, and production patterns
- No CI/CD pipeline, no staging environment, and manual deployment processes
What I Did
- Full Architecture Review: Conducted a comprehensive audit of the entire codebase, infrastructure, and deployment pipeline. Documented every critical, high, and medium-priority issue with a prioritized remediation plan.
- Critical Fixes: Identified and resolved security vulnerabilities, data integrity issues, and performance bottlenecks that would have blocked the launch.
- Long-Term Technical Strategy: Built a technical roadmap aligned with the business goals, covering architecture evolution, scaling plan, and technology choices for the next 12-18 months.
- Tech Stack Improvements: Updated and improved the technology stack to production-grade standards, replacing vibe-coded patterns with battle-tested approaches.
- Release Readiness: Prepared the platform for its first public release, ensuring the team had a fully functional, tested, and deployable product ready for marketing and sales.
- Team Enablement: Left the development team with clear documentation, coding standards, and a roadmap they could execute independently.
Key Outcome
Transformed a fragile vibe-coded prototype into a production-ready fintech platform, giving the founders confidence to launch and the development team a clear path forward.
