Independent engineering judgement for complex web platforms
Digital transformations and web-platform programmes are complex. Kavanagh Digital provides independent programme assurance, recovery, and platform due diligence to help you assess major commitments, stabilise delivery, and recover lost momentum.
Led by John Kavanagh, with more than two decades of engineering and technical leadership, including work with HSBC, Virgin Atlantic & Holidays, and John Lewis.
How we can help
Support for your next tech decision.
We help before a major digital commitment, at the first signs of delivery difficulties, or when a platform’s claims need checking.
About Kavanagh Digital
Deep engineering experience. Personal responsibility.
A trusted partner for difficult web-platform decisions and programmes in distress, combining senior hands-on engineering experience with independent judgement.
Kavanagh Digital Ltd. was founded by John Kavanagh. He leads every review, conducts our core investigations, and takes responsibility for the conclusions.
Kavanagh Digital is based in London and works with clients worldwide. John is based in Brighton.
For more than two decades, John has built and maintained complex web platforms and helped teams deliver digital transformations. His background spans hands-on development, front-end architecture, and senior engineering leadership.
His work covers React, Next.js, TypeScript, content platforms, and migrations, alongside performance, accessibility, and technical SEO. He follows technical decisions through the architecture, code, and working software, and explains their implications to engineers, stakeholders, and senior leadership.
Relevant experience
Engineering judgement grounded in delivery.
Selected experience from John’s engineering career, spanning complex replatforms, inherited codebases, and technical delivery.
A phased replatform
John helped lead the replatform of twelve disparate applications, consolidating the airline and holidays platforms around shared architecture, with load testing of the rebuilt flight-results application.

As lead developer, John helped the team improve upon three fragmented codebases, testing a React component across them in turn before progressively introducing a new design system and shared components.

During an agency transition, John led front-end delivery for three brands, preserving usable inherited work, introducing reusable components on a new multi-tenant app, and establishing a shared delivery workflow.

John investigated third-party scripts, their performance impact, and ownership, helping the team remove redundant code and improve the performance of a complex live platform.

How we work
From investigation to your next step.
Talk through what you need
We start with your programme, the decisions you face, the decisions that have already been made, and your deadline. Together, we establish where a review would help and agree the scope, fees, and access before work begins.
Understand the work
We speak with the people funding, leading, and delivering the programme and examine the software itself. Understanding their expectations and constraints alongside the engineering evidence helps us see what is working and what needs attention.
Work through the findings
John talks you through the written report and recommended next steps in a sponsor briefing. You have time to question the findings, discuss the options, and consider what each would mean for your programme.
We can also brief your wider teams, suppliers, agencies, and other stakeholders. We regularly work with everyone from junior engineers to the C-suite. If you need hands-on technical leadership to help stabilise or recover your delivery, we can discuss that too.
