What is the difference between FinTech product engineering and software development?
Software development focuses on implementing applications and system functionality. Product engineering covers a broader lifecycle, including product discovery, architecture, development, testing, deployment, performance improvement and continued product evolution.
Can Azilen modernise existing banking or financial software?
Azilen supports legacy application modernisation through architecture assessment, code refactoring, application reengineering, cloud migration and integration development. The approach depends on the existing system, business dependencies and modernisation objectives.
Can custom FinTech software integrate with existing banking systems?
Yes. Custom financial applications can be designed to integrate with core banking platforms, payment services, CRMs, credit bureaus, identity verification providers and other systems through APIs, middleware and appropriate integration patterns.
Does Azilen provide KYC and AML software development?
Azilen can support the engineering of KYC and AML capabilities, including onboarding workflows, screening integrations, transaction monitoring, risk assessment and case management. The project scope depends on the required functions and existing compliance technology.
How is security addressed during financial software development?
