    Frequently Asked Question(s)

    What types of FinTech products do you develop?

    We develop mobile banking apps, personal finance tools, investment platforms, budgeting apps, payment systems, crypto wallets, and internal tools for financial institutions. Each product is built to align with specific business and regulatory needs.

    How do you handle security and compliance in FinTech projects?

    We follow best practices in secure development, including encryption, role-based access control, and secure API architecture. We also work with clients to align with compliance requirements such as PSD2, PCI DSS, GDPR, and local banking regulations.

    Can you integrate AI or machine learning into financial products?

    Yes. We implement AI-driven features like fraud detection, expense categorization, credit scoring, investment advice, chat-based financial assistants, and real-time anomaly detection — all designed to improve automation and decision-making.

    What technologies do you use for building FinTech platforms?

    We work with a range of modern technologies depending on your product type. For mobile apps, we use Swift (iOS), Kotlin (Android), and cross-platform frameworks like Flutter or React Native. On the backend, we typically use .NET, Node.js, Python, and PostgreSQL. We also deploy to secure cloud platforms like AWS or GCP, with infrastructure optimized for compliance, scalability, and performance.

    What’s the typical engagement process for FinTech projects?

    We start with a discovery or technical scoping phase (if needed), then move into UI/UX, development, and testing. You’ll have a dedicated project manager and full transparency throughout — with support continuing post-launch.
