Client's Testimonial

"Speed and security were our top priorities, and they seemed mutually exclusive until we found Developers.dev. Their CakePHP POD built our MVP faster than we thought possible, and their expertise in FinTech security was evident from day one. They weren't just developers; they were partners in our launch. We closed our funding round thanks in large part to the functional, secure product they delivered."

Client Introduction

A well-funded US-based startup aimed to disrupt the small business lending space. They needed to build a Minimum Viable Product (MVP) for their loan origination platform quickly to secure a Series A funding round and onboard their first pilot customers. The platform required bank-level security, complex business logic, and integration with third-party credit scoring APIs.

Problem and challenges in FinTech

Problem

The startup had a brilliant idea and a short runway. They needed to build a functional, secure, and scalable MVP to prove their concept to investors and early customers. They couldn't afford the time to hire a local team or the risk of working with unvetted freelancers on a project with such high-security requirements.

Key Challenges

Migrating a massive, complex system with zero downtime

Aggressive Timeline

The MVP needed to be ready for investor demos in just 12 weeks.

Ensuring compliance with strict financial regulations

Bank-Level Security

The application had to handle sensitive financial data, requiring robust security measures from the start.

Integrating with dozens of third-party financial institutions

Complex Business Logic

The loan approval workflow involved multiple stages, user roles, and complex calculations.

Retraining their internal team to manage the new cloud-native environment

Third-Party Integrations

The platform needed to integrate seamlessly with APIs for credit scoring and identity verification.

Our Solution for FinTech

Our Solution

We deployed a complete Cross-Functional POD tailored for rapid, secure development. The team included one Senior CakePHP Developer, one Mid-Level CakePHP Developer, a QA Engineer, and a part-time Project Manager.

🚀 Rapid Application Development (RAD)

We chose CakePHP for its convention-over-configuration approach and built-in security features, which are ideal for accelerating MVP development.

🔒 Security-First Approach

From the outset, we implemented security best practices, including data encryption at rest and in transit, strict access controls, and input validation to prevent common vulnerabilities.

🔄 Agile Sprints

The project was broken down into six two-week sprints, allowing the founder to provide regular feedback and adjust priorities.

🔗 API-Driven Architecture

We built the core business logic as a set of secure REST APIs, allowing for a future mobile app or other integrations.

Implementation and Execution

Established a secure site-to-site VPN

Phase 1 (Sprint 1-2: Foundation & Core Models)

We set up the secure database schema, implemented user authentication/authorization, and built the core models for loans and applicants using the CakePHP ORM.

Parallel Environments Setup

Phase 2 (Sprint 3: Business Logic)

We developed the multi-step loan application workflow and the complex logic for the underwriting dashboard.

Kafka for event-driven communication

Phase 3 (Sprint 4: API Integrations)

We successfully integrated the Experian API for credit scoring and the Veriff API for identity verification.

Monitoring and observability stack

Phase 4 (Sprint 5: Frontend & UI)

We built a clean, functional user interface for both borrowers and internal underwriters using Bootstrap.

Automated performance and penetration testing

Phase 5 (Sprint 6: Testing & Deployment)

The QA engineer performed rigorous testing, including security penetration testing, before deploying the application to a secure AWS environment.

Final cut-over during low-traffic windows

Phase 6 (Continuous Communication)

Daily stand-ups and a shared Slack channel ensured the founder was always aware of the project's status.

Positive Outcome

⏱️ On-Time Delivery

The MVP was delivered in exactly 12 weeks, ready for investor demonstrations.

💰 Successful Funding

The startup successfully closed its $10M Series A funding round, with investors citing the quality and security of the MVP as a key factor.

🚀 Pilot Program Launch

The platform was stable and secure enough to onboard its first 10 pilot customers immediately after launch.

🏗️ Scalable Foundation

The well-architected codebase provided a solid foundation for future development post-funding.
