What types of fintech software can you develop?

We have extensive experience in building all kinds of fintech products, from lightweight payroll software or wealth management tools development all the way up to ERP software with in-depth Big Data analytics.

Here is the list of other fintech solutions we can develop for you:

What does a financial software developer do?

Fintech software development engineers design, deliver, maintain, and update fintech software for financial institutions and products with a financial element. Fintech developers are skilled in full-scale mobile and web development, as well as technologies like DevOps, cloud computing, AI, IoT, and blockchain.

Is fintech software development outsourcing a good idea?

Fintech product development outsourcing is an excellent idea if you need expert, cost-efficient, and reliable development and don't have the time or means to hire in-house. At Relevant, we offer extensive cybersecurity and NDA/SLA agreements to cover dealing with sensitive data.

How do you make a highly secure and compliant financial platform?

Fintech app security solutions are required to meet a wide range of security requirements, including identity management, built-in cybersecurity measures, and compliance with global and regional security legislations. This means fintech software development requires expertise in data encryption, role-based access control, DevSecOps, secure application logic with ephemeral passwords, and rigorous penetration testing.

How can I test your expertise?

Before you hire fintech developers from Relevant, you can check their skills and expertise with test tasks, talk the project over in a technical call, or contact one of the companies featured in our case studies.
