How AI is changing software development in financial services

Financial services companies are under constant pressure to keep up with customer expectations. But building software in this environment isn’t easy. With outdated systems, heavy documentation, and tight compliance rules, development teams often face significant challenges. This is where AI is making a measurable difference.

Smarter and faster software development

AI-powered platforms are enabling financial services companies to develop software faster, more accurately, and with full compliance. Unlike generic AI coding tools, enterprise-grade platforms like Wynxx by GFT are purpose-built for the financial industry.

In general, AI-powered coding assistants boost developer efficiency by automating routine tasks and suggesting accurate code, helping teams deliver faster with fewer errors as part of the code writing process.

By embedding AI directly into CI/CD pipelines, Wynxx improves developer efficiency too, but extends the gains into non-coding parts of the software development lifecycle, further accelerating modernisation, and reducing risk. The platform especially helps teams modernise legacy applications, migrate complex systems, and implement updates without disrupting compliance or operations.

Importantly, Wynxx does not compete with tools like GitHub Copilot or AWS Q. Instead, it complements them, aggregating productivity gains and creating cumulative efficiency savings across the development lifecycle.

Key benefits of AI in software development

Here are some of the ways AI, and specifically Wynxx, helps financial services teams deliver software faster whilst remaining compliant:

• Streamlined documentation and testing – Automates repetitive tasks to reduce errors and free up developer time for higher-value work.
• Accelerated legacy system upgrades – Speeds up mainframe modernisation and other legacy system updates by over 40%, reducing risks and downtime.
• Built-in compliance and governance – Automatically flags potential regulatory issues, generates audit-ready records, and embeds regulatory checks into development workflows.
• Improved onboarding and developer efficiency – New developers can ramp up faster with AI-guided assistance, integrated workflows, and automated code review/fixing.
• Higher productivity and quality – By handling repetitive or complex tasks, AI allows teams to focus on innovation, improving overall software quality and reducing time-to-market.

Built for compliance

In financial services, compliance is non-negotiable. Wynxx is designed with security and governance in mind. It integrates with monitoring tools, generates audit-ready documentation, and can enforce regulatory checks automatically, reducing delays in approvals and lowering operational risk.

Choosing the right AI platform

When evaluating AI for software development, consider:

• Will it integrate seamlessly with your existing tools and systems?
• Can it support complex, cross-departmental projects?
• Does it provide the oversight and reporting needed for compliance?
• Will it help you identify and mitigate risks early?

Platforms like Wynxx are already demonstrating value across major financial services organisations, making it easier to build, test, and deploy new products without compromising on security, compliance, or quality.

Final thoughts

AI is no longer optional for financial services companies seeking speed, compliance, and competitiveness. Platforms like Wynxx by GFT help teams modernise legacy systems, improve onboarding, and integrate AI-driven efficiency directly into development pipelines. Combined with complementary tools like GitHub Copilot and AWS Q, Wynxx empowers developers to do more, faster, and with greater accuracy, creating a measurable impact on productivity and business outcomes.
