Legacy Projects

Legacy code isn’t a red flag. It’s our specialty.

From modernizing legacy Delphi ERPs to dismantling aging monoliths, we recover and refine the business logic others have left behind. As embedded experts or a managed delivery team, we take ownership where others hesitate and ensure every system emerges more stable, scalable, and maintainable.

Hospitality Tech

Mid-Size Enterprise

United Kingdom

The client's mobile app was bogged down by unmaintainable code that caused constant bugs and delays. We refactored the system and created a clean, modular architecture that solved recurring issues and streamlined development.

The Problem

A critical Delphi 6.0 platform still in daily use by thousands of clients

Loss of key staff with deep domain expertise

Shortage of developers with Delphi knowledge

Escalating costs for UK-based contractors

Growing risk of system downtime and lack of support continuity

Our Solution

Vetted and presented 8 skilled Delphi 6.0 engineers

Facilitated interviews that led to
hiring 5 engineers for immediate
team augmentation

Set up structured, ongoing knowledge-sharing sessions to prevent expertise silos

Built redundancy into the engineering team to ensure continuous system support

The Outcome

42% annual cost reduction in the product department

Eliminated dependency risk through redundancy and team scaling

Sustained platform reliability for the Delphi-based application

Hospitality Tech

Enterprise Company

United Kingdom

The client's React Native mobile app was bogged down by unmaintainable code that caused constant bugs and delays. We refactored the system and created a clean, modular architecture that solved recurring issues and streamlined development.

The Problem

Any change introduced new bugs elsewhere

Fixes that should take an hour stretched into days or weeks

Logic for core features was scattered across multiple files

Developers struggled to understand and maintain the code

Unnecessary abstractions made the system overly complex

Our Solution

Rebuilt key modules to improve structure and maintainability

Introduced clear boundaries between pricing, selection, and rendering logic

Removed overengineered “Node” abstractions and replaced them with clean MVVM-inspired patterns

Eliminated redundant and copy-pasted logic, reducing file sizes by up to 80%

Renamed variables, functions, and files for readability and reliability

The Outcome

Fixes that previously took a week now take hours

Refactored modules were reduced from 1500+ lines to around 300 lines

Eliminated recurring bugs tied to tightly coupled logic

LegalTech

Large Enterprise

United kingdom

A leading UK intellectual property firm depended on an aging HCL Notes environment with few experts left to support it. Its continued use across hundreds of staff introduced serious operational risk as the platform became harder to maintain.

The Problem

Frequent integration issues with tools like Outlook and SharePoint

Business-critical workflows and documents relied entirely on the platform

Very few experts still understand HCL

Manual handling required for user management, replication conflicts, and compliance tasks

Our Solution

Provided a rare HCL Notes specialist on a flexible retainer

Maintained and enhanced workflows, forms, and document processes

Improved interoperability through exports and secure email automation

Documented key legacy knowledge to reduce operational risk

Delivered seamless remote support as part of the client’s IT team

The Outcome

Achieved zero downtime throughout the engagement

Reduced internal IT workload by 20+ hours per month

Delivered fast feature updates and smoother external integrations

Sustained the legacy system without requiring an immediate migration

“I selected Expert Allies over other vendors because of their exceptional breadth of technology stacks and proven problem-solving capabilities. Their team of experts are exceptional at analysing complex problems, developing effective strategies, and implementing solutions that drive tangible results. Their commitment to excellence and their ability to deliver high-quality outcomes make them a valuable partner for any organisation. My partnership with EA has been a valuable resource to me over many tears, simply put, they have never let me down.”
