Client's Testimonial

"As a startup, speed and trust are everything. Developers.dev delivered on both. They built our entire platform from scratch in just six months, navigating the complexities of FinTech regulations and multi-tenancy with ease.

Client Overview

A well-funded FinTech startup based in Berlin, Germany, aimed to disrupt the small business lending market. Their vision was a SaaS platform that used AI to provide instant credit risk analysis and loan approvals. They had the AI models and the business plan but needed a technology partner to build the secure, scalable, and compliant web application to deliver their service across Europe.

Problem

The client needed to go from concept to a market-ready product quickly to secure a first-mover advantage. The platform had to be highly secure to handle sensitive financial data, scalable to support rapid user growth, and architected for multi-tenancy to serve thousands of individual business customers. They lacked the in-house development capacity to build such a complex application on their aggressive timeline.

Key Challenges

Zero Downtime Migration

A fully functional, secure MVP needed to be ready for launch in 6 months.

Sub-2-Second Load Times

The platform had to comply with GDPR and financial industry security standards.

Complex Multi-Tenant Architecture Challenge

Unique UX Creation

Each customer's data had to be securely isolated while using a shared infrastructure.

High Concurrency Handling

The platform required integration with financial data providers, identity verification services, and payment processors.

Our Solution

We deployed a cross-functional "SaaS Launch" POD, leveraging Yii for its robust security features and rapid development capabilities. Our approach was centered on an Agile methodology with two-week sprints to ensure continuous progress and feedback.

🔒 Secure-by-Design Architecture

We designed the platform architecture with security as the primary consideration, implementing database-level data segregation for multi-tenancy, end-to-end encryption, and strict access controls.

🔗 API-First Development

We built the core logic as a set of secure RESTful APIs using Yii. This allowed the frontend team to work in parallel and ensured the platform would be ready for future mobile or partner integrations.

🏃 Agile Sprint Execution

We worked in tight, two-week sprints, delivering testable increments of the product. This allowed the client to provide regular feedback and make adjustments, ensuring the final product perfectly matched their vision.

🛡️ DevSecOps Pipeline

We implemented a CI/CD pipeline with integrated security scanning (SAST/DAST) to catch vulnerabilities early in the development process, ensuring continuous compliance and security.

Implementation and Execution

Migration Strategy

A POD of 6 experts was assigned: 1 Tech Lead, 2 Yii Backend Devs, 1 Vue.js Frontend Dev, 1 DevSecOps Engineer, 1 QA Automation Engineer.

Headless Architecture Design

The infrastructure was built on AWS using a serverless architecture where possible to manage costs and scale automatically.

Frontend Development

Yii's Role-Based Access Control (RBAC) was heavily utilized to manage complex user permissions.

Data Migration & QA

We integrated with Stripe for subscription billing and Plaid for connecting to users' bank accounts.

Performance & Load Testing

A comprehensive test suite was created, including security-focused tests, to ensure the platform's integrity.

Go-Live

The platform was delivered on time, passing a third-party penetration test with flying colors before launch.
