Overview
Web Development, explained
Web applications are where most business workflows now live: customer portals, marketplaces, booking systems, internal tools and SaaS products. A good web application is fast, secure, easy to use and straightforward for your team to extend after launch.
We design and build web applications end to end, from user flows and architecture to frontend, backend, integrations, testing and deployment. Our portfolio includes a UK food marketplace, an aircraft marketplace, an invoice processing system and a cloud payment gateway, each with different scale and integration needs.

Engineers who build
Recommendations come from the people who design, code and support the software, so they reflect real implementation effort.
Visible progress
A shared backlog, regular demos and recorded decisions keep you informed without chasing updates.
Practical AI
Evaluation sets, review steps, cost limits and monitoring are part of every AI feature we ship.

Cost
What shapes the cost of your project?
There is no useful price without scope. These are the factors we review when preparing an estimate, and the estimate lists every assumption so you can see what would change it.
01
Platforms
Web, iOS, Android or all three, and whether apps are native or cross-platform.
02
Features and roles
The number of user journeys, roles and business rules in the first release.
03
Integrations
Payments, maps, CRMs, ERPs and third-party APIs each add scope.
04
Design depth
From using a component library to a fully custom design system.
05
Data migration
Moving and validating data from existing systems.
06
Non-functional needs
Performance, security, availability and compliance requirements.
Engagement models
Choose the engagement that fits your next step.
Dedicated Team
For a changing roadmap or ongoing development. Agree roles and working process, then manage priorities through a shared backlog.
Best for team extension and long-term product work.
Scoped Project
For a defined product or milestone. Align on requirements, deliverables and acceptance criteria, with changes reviewed before they affect the plan.
Best for MVPs, integrations and focused releases.
Maintenance and Improvement
For software that already exists. Start with a technical review, then agree support routines and planned improvements.
Best for live applications and modernisation.
FAQ
Questions about web development
Which technologies do you use?
We commonly use React, Angular, Vue and Next.js on the frontend and Node.js, .NET, Python, PHP or Ruby on Rails on the backend, chosen to fit your requirements and team.
Can you work on an existing application?
Yes. We start with a code and architecture review, then improve or extend the application in planned steps.
Do you design the user interface as well?
Yes. Product design is part of our service, or we can work from your designs.
How do you ensure security?
Through secure coding practices, access control, dependency checks, encrypted data and testing of sensitive workflows.
How long does a web application take?
It depends on scope. A focused first release is often planned in months rather than weeks; we estimate after discovery.
Who hosts the application?
Usually your own cloud account on AWS, Azure or Google Cloud so you keep ownership.
Do you provide support after launch?
Yes, through maintenance and improvement engagements.
Can you work on only the frontend or backend?
Yes. We can focus on a defined component or collaborate with your team across the application.
Can you modernize an existing web platform?
Yes. A technical review helps identify what to retain, improve or replace before planning the work.
How are pricing and timelines determined?
We review requirements, technical complexity, team needs and delivery constraints before proposing an engagement. Estimates list assumptions and what may change the plan.
Can we discuss a project under an NDA?
Yes. Let us know before sharing confidential materials so we can agree confidentiality terms first.
