Understand
We learn how the product needs to work: its users, workflows, data, systems and operational constraints.
Web application development services
For more than 15 years, DabApps has designed, built and supported web applications, platforms and APIs that people rely on every day: staff portals, reporting tools, integrations and products that need to keep working as they evolve.
Web applications people rely on
A web application can give staff and customers one place to complete tasks, share information and see what happens next. It can reduce repeated data entry, replace manual handovers and make it easier to run a service as more people use it.
Teams come to DabApps for web application development: to shape a first version, rebuild a legacy system, join up existing tools or support a product after launch. We turn that into a plan and take responsibility for design, engineering and what follows.
When requirements need to be worked out alongside the people using the software, our engineers can work directly with your team to investigate and implement improvements. Our guide to forward deployed engineering explains this embedded approach and when a wider delivery team helps.
WHAT WE BUILD
Web apps that fit the way teams work
Web application development brings together product design, browser interfaces, backend systems, APIs and data. We plan for the roles, permissions, reporting and existing systems that make the software dependable in day-to-day work.
- B2B SaaS products
- Workflow and case-management systems
- Customer, partner and staff portals
- Dashboards and reporting tools
- API and integration layers
- Internal operational platforms
COMMON STARTING POINTS
New web apps, takeovers and ongoing support
Custom web application development makes sense when existing tools cannot support the way your business works. You may also have an application that needs a new team to maintain it. We review what is in place and agree responsibility for fixes, dependencies, hosting and continued development. For specialist support with a Django codebase, see our Django support and maintenance service.
- Building a new product or platform from scratch
- Rebuilding or modernising a legacy system
- Creating APIs and integrations between existing systems
- Evolving a product beyond its original architecture
- Adding AI-enabled features to products already in use
- Moving core workflows out of spreadsheets
- Taking over an existing application from another supplier
- Ongoing application maintenance and development
How a web application project moves forward
Define
We shape the scope, architecture and delivery plan, addressing permissions, integrations, migration and risk early.
Build
Product design and engineering move together through implementation, testing, migration and a controlled release.
Support
After launch, we monitor the product and keep improving it as needs and systems change.
WHY DABAPPS
A partner for the life of the product
DabApps has worked with Agilio since 2015, helping rebuild and evolve iComply, which supports more than 18,000 dental professionals. Our work with Novo Nordisk and Firefly brings experience of clinical trial recruitment, connected equipment and the operational decisions behind those products. Our SaaS experience includes helping Futrli’s founding team develop financial forecasting software and building a subscriptions management system for Agilio.
- Planning for permissions, integrations and migration before the build
- Product design and engineering considered together
- Experience rebuilding software people already depend on
- Support and continued development after launch
Client success stories
These projects show the range of the work: replacing fragmented clinical systems, turning live operational data into useful tools and supporting a compliance platform used by thousands of professionals.
Novo Nordisk
The recruitment platform supported growth from 5,000 recorded potential trial participants in 2020 to nearly 30,000 in 2024.
Firefly Glow
Glow helps Firefly investigate equipment remotely, reducing travel, while customers can check performance, CO2 and fuel savings themselves.
Agilio iComply
More than 18,000 dental professionals rely on iComply to manage compliance across the UK. We've worked with Agilio since 2015 to help the product evolve alongside their customers' needs.
What our clients say
“Glow has changed how we manage and showcase our hybrid power systems. We can support sites remotely, and customers can clearly see the CO2 and fuel savings for themselves.”
Andy Mead, CEO at Firefly
The stack supports the product
We work with Django, Django REST Framework, Python, React, React Native, PostgreSQL, APIs, data platforms and cloud infrastructure, choosing the stack to fit the problem. The product still needs to make sense to the people using, operating and sponsoring it, so related work often spans product design, data, AI, mobile and sector constraints.
Questions about web application projects
Can you take over an existing or legacy web application?
Yes. We review the codebase, architecture, data, integrations and deployment, alongside your team's knowledge of the product. We agree access, a handover and the first maintenance or development priorities. That gives you a plan for supporting the existing application and deciding what needs to change.
Can you build the APIs and integrations the application needs?
Yes. We build APIs, connect third-party services and work with existing systems, planning data ownership, permissions, failure handling and support as part of the product.
How do you approach sensitive data and permissions?
We design roles, access rules, data visibility and audit requirements around real workflows. Security and privacy shape discovery, architecture, implementation, testing and operation.
How is a web application project scoped?
We begin with the users, business goal, systems, data and constraints. From there we define a useful first release, the main risks and a delivery approach that leaves room to evolve.
Can you host and support the product after launch?
Yes. We can take responsibility for hosting, monitoring, maintenance, support and continued development, keeping the application dependable as it evolves.
