Over two decades building things that matter at scale
Get senior engineering that owns the technical problem end to end. Amplify Digital is a React, Next.js, and TypeScript consultancy founded by Kymme Hayley, with a trusted network of specialists brought in when the work demands it.
The approach
We work on applications where performance is revenue and reliability is non-negotiable. It is a standard learned at scale, and we hold every engagement to it.
Our focus is performance and strong foundations: systems that let teams move faster while staying reliable and maintainable. We've led design systems, shared component platforms, and frontend standards in both greenfield and mature codebases.
We're pragmatic and collaborative. We guide technical decisions and mentor engineers, and we get hands-on. We use AI-assisted development, including Claude Code, to accelerate delivery without lowering production-grade quality.
We don't fill seats or bill hours. We own the problem end to end, bring in specialists from our network when the work demands it, and deliver outcomes.
Differentiators
End-to-end ownership
You get one team that owns the engagement, finds the problem wherever it lives, and leads the solution, not just a frontend layer handed back to you.
Revenue-critical scale
Ticketmaster Global Checkout. M&S eCommerce. Just Eat Payments. We've worked on applications where performance directly equals revenue.
AI-augmented delivery
Production experience with Claude Code, reusable skills, and MCP integrations. Hands-on, not theoretical knowledge.
Consultant model
You get a strategic partner focused on direction and outcomes, not billable hours, bringing in backend, design, or infrastructure specialists from our network when the work demands it.

Kymme Hayley
Founder, Amplify Digital
Kymme is the founder of Amplify Digital, with over two decades building high-traffic web applications at scale. Her experience spans Ticketmaster Global Checkout, M&S eCommerce, Just Eat, HDR UK, and NatWest: systems where performance is revenue and reliability is non-negotiable. She started Amplify to bring that depth to organisations that need senior technical leadership, end to end.

Driving architectural decisions, contributing to API design, and delivering scalable, resilient solutions used by millions worldwide. Using Claude Code to accelerate delivery, building reusable skills and MCP integrations for debugging and optimisation.

Built config-driven systems for dynamic forms, delivered strict TypeScript standards, Storybook, and mentored engineers across the team.
Delivered frontend consultancy for a large-scale housing platform for a London Borough Council. Built React/TypeScript micro-frontends within a modular, scalable architecture.

20 years of experience across financial services, gaming, insurance, public sector, and SaaS. Built the breadth of domain knowledge that underpins Amplify Digital's cross-sector advisory capability.
Kymme's dedication and professionalism when placed within a company is astounding. Not only does she come with capabilities and logical thinking which are second to very few in my experience, but she's also not shy to vocalise opinions — which truly helps avoid pitfalls early on. The biggest impact for us was Kymme's immediate bigger picture view of designs she wanted to put in place to ease future development, with an aim to be purely feature driven.
