Overview
Off-the-shelf software forces standardised processes, which means your enterprise ends up operating much like its competitors. FA3 builds proprietary, business-critical applications that make the most of your specific operational strengths and open up new revenue opportunities.
At the same time, we tackle the technical debt that holds established enterprises back. We modernise decades-old monolithic applications, refactoring them into resilient, cloud-native microservices that integrate cleanly with AI capabilities and external data systems.
What we do
- Custom enterprise software engineering: We use modern tech stacks (React, Node, Go, Rust) to build secure, low-latency applications that handle complex business logic and process millions of transactions per second.
- Legacy modernisation: We safely decouple tightly integrated legacy systems, whether mainframe or early-web architectures, and rebuild them as independent microservices without disrupting your ongoing operations.
- API strategy and development: We design and expose secure APIs so your applications can integrate with third-party partners, IoT systems and newly acquired subsidiaries.
- Mobile and front-end engineering: We build cross-platform and native mobile experiences that are well-designed, accessible and optimised for conversion and engagement.
How we work
We hold ourselves to high engineering standards. We use strict test-driven development (TDD), continuous integration (CI/CD) and thorough code reviews to produce software you can depend on.
We build for the long term. Our architectures are modular and decoupled, so that when new technologies appear, such as generative AI or advanced edge computing, your applications can adopt them quickly rather than requiring another multi-year rebuild.
