It is possible, though it is not recommended. Every fintech project is complicated, so you need software architecture to complete it effectively. Software architecture provides the foundation for designing and developing a software system, defining its structure, components, interactions, and overall behavior. The product may lack scalability, performance, maintainability, and other essential qualities without proper architecture.

If you want to achieve maximum efficiency and ensure your startup’s scalability, then yes. Startups often have limited resources and tight timelines, making it even more important to have a well-defined architecture. A straightforward software architecture helps align development efforts, facilitates future scalability, and enables efficient development in further stages. If you launch a project without software architecture, you will face risks connected to scalability, user base growth, and modernization.

Fintech systems deal with sensitive financial information, such as user accounts, transactions, and personal data. Therefore, a robust security framework is essential to protect against unauthorized access, data breaches, and fraudulent activities. So, a key feature of fintech architecture is security.

Having a business analyst can be beneficial for software architecture development since they will actively participate in collecting product requirements. They will focus on understanding the business needs and requirements and facilitate communication between business stakeholders and the development team. Business analysts can also help you find the most appropriate vendor integrations for your business, such as KYC, KYB, AML, and others, as this specialist can analyze your business needs and find the third-party services crucial for your company. Essentially, they will fuel your product vision as they can align the proposed solution with your plans and long- and short-term goals.
