Client's Testimonial

"As a startup, speed and trust are everything. Developers.dev delivered on both. They provided us with an entire, high-functioning engineering team in a matter of weeks. Their FinTech Mobile Pod and Java Microservices Pod worked in concert to build a platform that is not only robust and secure but was also ready for our initial launch 5 months ahead of our most optimistic internal schedule. Their process maturity gave our investors immense confidence."

Client Overview

An ambitious, venture-backed FinTech startup in the EU (based in Germany) aiming to launch a new platform for SME lending. They had the business vision and funding but needed a technology partner to build the secure, scalable, and compliant platform from scratch, and do it quickly to capture market share.

Problem

The startup needed to build a complex, multi-tenant SaaS platform that could handle loan applications, risk assessment, and payment processing. The platform had to be compliant with EU financial regulations (including PSD2 and GDPR), highly secure to handle sensitive financial data, and built on a scalable architecture that could support rapid user growth.

Key Challenges

Speed to Market

They were in a race against competitors and needed to launch an MVP within 6 months.

Regulatory Compliance

The platform had to be built with GDPR and PSD2 compliance at its core.

Security

As a financial platform, it required bank-grade security features to protect against fraud and data breaches.

Talent Acquisition

Hiring a full, experienced in-house team of .NET developers, security experts, and mobile developers in Germany would be slow and extremely expensive.

Our Solution

The client engaged two of our specialized PODs: the "FinTech Mobile Pod" and a custom "Java/.NET Microservices Pod".

⚙️ Microservices Architecture

We designed a cloud-native architecture using .NET 8 for the core backend services (loan origination, risk analysis) and deployed them as containerized applications on Azure Kubernetes Service (AKS). This allowed for independent development, deployment, and scaling of each component.

🔒 Security-by-Design

We implemented a DevSecOps approach, integrating security controls throughout the CI/CD pipeline. This included using Azure Key Vault for secrets management, implementing OAuth 2.0 and OpenID Connect for authentication, and conducting continuous vulnerability scanning.

⚖️ Compliance Focus

Our team, including a compliance specialist, designed the data models and business logic to be GDPR-compliant from the start (e.g., data anonymization, right to be forgotten). We also integrated with Open Banking APIs to meet PSD2 requirements.

📱 Cross-Platform Mobile App

The FinTech Mobile Pod used .NET MAUI to develop a cross-platform mobile app for iOS and Android, allowing SMEs to apply for loans and manage their accounts on the go. This saved significant time and cost compared to building two separate native apps.

Implementation and Execution

UI/UX Design Sprint

We started with a two-week "UI/UX Design Sprint" to rapidly prototype and validate the user journeys for both the web and mobile applications.

Agile Sprints

The microservices and mobile teams worked in parallel agile sprints, coordinated by a dedicated project manager from our side.

Azure DevOps Environment

We established a secure Azure DevOps environment with automated build, test, and deployment pipelines to AKS.

Security and Compliance Reviews

Regular "Security and Compliance" review meetings were held with the client's legal and advisory teams.

Third-Party Service Integration

We integrated with third-party services for identity verification (KYC) and credit scoring via secure APIs.

Independent Penetration Test

The platform underwent a rigorous, independent penetration test before the MVP launch.

Positive Outcome

⏱️ MVP Launched in 5 Months

We delivered the fully functional, secure, and compliant MVP in just 5 months, beating the client's target by 50%.

✅ Passed Security & Compliance Audits

The platform passed all required security and regulatory audits on the first attempt, allowing for a smooth market entry.

📈 Scalable Foundation

The microservices architecture has allowed the client to seamlessly add new features and scale their user base by 10x in the first year without performance degradation.

💰 60% Lower Development Cost

The total cost of building the platform was estimated to be 60% lower than if they had hired a comparable team in Germany.
