Every organisation has them. Applications built years ago that still run critical business processes, but that no one wants to touch. The original developers have moved on. The technology stack is out of support or approaching end of life. And every change request takes longer, costs more, and carries more risk than it should.
At JFDI, we combine deep technical experience across multiple technology stacks with proprietary analysis and conversion tooling that lets us understand what your application actually does before we begin rebuilding it.
Why Legacy Applications Become a Problem
Technology Falls Behind
The underlying framework or platform approaches end of life, and security or compliance exposure grows.
Key Knowledge Leaves
The people who built and understood the application have moved on. No one is entirely sure how it all works.
Integration Becomes Fragile
Connecting to newer cloud services was never part of the original design, making every integration a risk.
Costs Accumulate
The cost of keeping legacy applications running starts to outweigh the cost of replacing them.
The business logic inside these applications still has real value. The goal is to preserve it while moving to a platform that gives you a sustainable path forward.
Four Modernisation Routes
We support four proven modernisation routes, each suited to a different strategic outcome.
Bespoke Cloud Development
For applications with complex domain logic, deep integration requirements, or demanding non-functional needs. We rebuild on Azure or AWS with complete architectural freedom.
Locodium
JFDI’s own application platform. Bridges the gap between low-code speed and properly engineered software — ideal for replacing legacy form-driven interfaces with complex workflow logic.
Microsoft Power Platform
For organisations on Microsoft 365 where legacy workflows, forms and approvals fit naturally within the Microsoft ecosystem. We know when Power Platform is a genuine fit.
Appian
For regulated environments with complex case management, compliance-driven workflows, and strong auditability requirements where an enterprise process platform is the right answer.
Why JFDI Is Different
The hardest part of any modernisation project is not the rebuild. It is understanding what you already have. Legacy applications are often undocumented, built on varied technology stacks, and understood in full by nobody still in the organisation.
Our proprietary tooling and AI-driven agentic engineering techniques analyse existing applications directly, regardless of the underlying technology. We extract the actual business logic, data structures, and integration points from the application itself rather than relying on incomplete documentation or institutional memory.
Faster, More Accurate Discovery
Our tooling does the heavy lifting, not months of requirements workshops.
Lower Risk of Losing Logic
We work from what the application actually does, not what someone remembers.
Genuinely Platform-Agnostic
We recommend the route that fits your needs, not our capabilities.
Cross-Platform Tooling
Our analysis works across all four modernisation routes.
Knowledge Transfer
Every engagement leaves your team able to maintain what we build.
What Clients Are Looking to Achieve
Reduced Operational Risk
Move off unsupported or fragile technology before it fails.
Lower Maintenance Costs
Cut long-term support costs with modern, maintainable platforms.
Greater Flexibility
Evolve workflows and integrations without fighting the platform.
Stronger Compliance
Improved security and compliance posture across your application estate.
Attract Talent
A modern platform that developers actually want to work on.
Safe Migration Path
Preserve critical business logic and reduce delivery risk.
For organisations evaluating a specific platform move, we provide focused migration assessments for Appian and Power Platform. We also help organisations tackle shadow IT debt and SharePoint-based systems that have outgrown the platform.
