Focus on back-end in app development

TypeScript Developers For Hire

Back-end does to apps what back office does to businesses: it ensures dynamic data flow and smooth operation of all customer-facing elements. Without a solid base of server-side code and database management, the user interface cannot process any incoming requests.

Although invisible to users, back-end development has direct impact on app performance, security, and the overall user experience. Most of system architecture and app logic is also rooted in the back-end and, as such, it forms the foundation of a solid development process.

Understanding the role of back-end in FinTech software development requires in-depth knowledge of financial processes and technological mastery to digitalize them.

Joining forces with a seasoned back-end development company gives you a unique competitive advantage

From designing and building MVPs to refining and optimising existing systems, Code & Pepper can become your strategic back up. Additional benefits include product development agility and best software engineering practices, such as Continuous Integration, Continuous Deployment, and Infrastructure as Code (including Terraform or CloudFormation).

Technology stack for back-end development

Back-end security in FinTech products

Speaking of code, software back-end is where the magic happens, but it’s also the first line of defence against cyber attacks. Security breaches and data leaks are among the biggest threats affecting both business owners and end users. That’s why back-end system development is at the centre of an effective security policy and risk management.

Implementing authentication protocols, access control and tools for safeguarding sensitive data are just the first steps towards regulatory compliance. Once your FinTech reaches that point, there is nothing stopping you from leveraging back-end software development to win customers’ trust and deliver supreme User Experience.

Custom back-end system development

Requirements

Before the team can roll up their sleeves to start coding, we need to define both functional and non-functional product requirements. To understand the product inside out, we define the scope of work, establish acceptance criteria, and prepare UI/UX design in the form of mockups and visuals.

Management

Scrum is our go-to method for effective collaboration, but for small projects (up to 3 months) we may also switch to Kanban. Whatever the scope, the team uses proven measurement techniques, such as scoping by story points or story points burndown per sprint, to determine development velocity and plan reliably.

Development process

Features of your application are thoroughly checked and analysed from all angles using top industry practices. These include: multiple types of tests, code reviews, Continuous Integration, and Continuous Deployment. Thanks to smart resource reallocation, you can scale your team size according to the current needs.

Technology

Code & Pepper developers are skilled in a number of technologies best suited for back-end software development. Flexible development plans enable us to support you with different technologies in optimal proportions: we can engage a team member part-time or full-time, depending on the demand.

One team policy

From day one, you can expect full transparency. Every resource produced by Code & Pepper in connection with the project will be shared with you, including code repository, team members’ timesheets, budget flow, risk logs, and source graphic files. Open communication is key: both on the client and team side.

NoMo

Mobile app development with extra focus on back-end code structure

NoMo app is a slick mobile solution for personal finance management created by DirectID (formerly The ID Co.): a UK-based leader in open banking and a long-term client of Code & Pepper. With NoMo, users receive custom recommendations for daily spending limits and can closely monitor their financial performance. Banking jargon is replaced by personalised in-app communication, helping users adopt healthier spending habits in a motivating and playful manner.

Code & Pepper was tasked with a complex refactoring of the PFM application.

Hexagonal architecture was implemented to achieve better support for cloud infrastructure, while rewriting back-end code using .Net enabled seamless integration with Open Banking API and easier maintenance. A dedicated iOS developer gave NoMo an extra performance boost by fixing issues with Objective-C.
