Bespoke Web App Development for SMEs

I design and build bespoke web applications for SMEs in London, Hertfordshire and Essex who have outgrown spreadsheets, generic SaaS tools or ageing internal systems. The focus is always on making your day-to-day operations easier, faster and more reliable – not on chasing the latest framework trend.

Whether you need a completely new system or a modern replacement for an existing one, I work closely with you to design a web app that fits how your business actually works.

Typical web apps I build

Examples of the kinds of bespoke web systems I deliver for SMEs:

  • Job, project and task management systems for contractors and service businesses
  • Scheduling and resource planning tools for vehicles, teams and equipment
  • Customer self-service portals for bookings, requests and document access
  • Online admissions, registration and onboarding portals for education providers
  • Internal CRMs and workflow tools tailored to your processes
  • Quote-to-invoice pipelines for specialist trades and subcontractors
  • Dashboards and reporting for management visibility
  • Web back-ends that support mobile apps used by field staff
  • AI-assisted tools for searching documents, legislation or internal knowledge
  • Modern front-ends for older databases that still do the job well

Built on solid, modern technologies

Most of my work is based on the Microsoft stack, which is well suited to SMEs that need robust, long-lived systems:

Most bespoke web apps I build use SQL Server, REST APIs and an offline-first Android app for engineers on site.

  • .NET / ASP.NET Core Razor Pages for maintainable, server-side web apps
  • SQL Server for reliable data storage, reporting and performance tuning
  • Bootstrap 5 for responsive, mobile-friendly interfaces
  • Authentication and access control appropriate to your environment (e.g. email/password, Azure AD, role-based access)
  • Clean APIs for integration with other systems, mobile apps or third-party services

Replacing ageing or fragile systems

Many SMEs I work with already have a “system” of some kind – often an old ASP.NET WebForms app, an access database, or a collection of spreadsheets and shared folders. These can be risky to maintain, slow for staff and difficult to modify.

I specialise in gently replacing or modernising these systems, so staff can continue working with minimal disruption while the new system is introduced in a controlled, low-risk way.

Designed around your workflow, not the other way round

Off-the-shelf products often force you to work the way the software expects. With a bespoke web app, we start with how your business already works – and then improve from there:

  • Workflows and screens that match the language your team uses day to day
  • Validation and business rules that reflect how you actually price, schedule and deliver work
  • Dashboards that show the information managers genuinely need to see each morning
  • Performance tuned around the most common tasks, not artificial demo scenarios

Who this is for

This service is a good fit if you are an SME in London, Hertfordshire or Essex and:

  • You are held back by spreadsheets, dated web apps or manual processes
  • You need a system that matches your business, not the other way round
  • You want to work directly with an experienced developer, not a rotating agency team
  • You value long-term support, performance and stability over short-lived experiments

Thinking about a bespoke web app?

If you have an idea for a new system or you’re worried about the fragility of an existing one, I’m happy to have a short, no-obligation conversation about what might be involved.
