Bespoke web & Android app development for SMEs

I build and modernise business-critical systems for small and medium-sized organisations — from internal job management platforms and customer portals to Android field apps that integrate cleanly with your back-office data.

Based in Hertfordshire, I work with clients across London and the UK, focusing on performance, maintainability and the real-world workflows your team relies on every day.

Fast & reliable

Performance-first .NET & SQL Server systems built to last.

Secure by design

OWASP-aware development, sensible access control and auditability.

Modernise legacy

WebForms to modern .NET, showing measurable gains.

Long-term support

Below are my core development services, followed by assurance & support options to keep your systems secure, resilient and well-managed once they’re live.

Core development services

Bespoke web app development

Custom-built web applications for SME workflows — operations, scheduling, CRMs, customer portals, job management and internal platforms. Built using robust modern technologies (.NET, SQL Server, Razor Pages).

  • Clean, maintainable architecture with long-term ownership in mind
  • Performance tuning and query optimisation where it matters
  • Secure authentication, role-based access and audit trails

Bespoke Android app development

Android apps for engineers, field staff and contractors — job reporting, photos, signatures, offline-first data capture and integration with your back-office system or SQL database.

  • Offline-first workflows with reliable sync
  • Device features: camera, GPS, barcode/QR, signatures
  • API integration designed for stability and versioning

Who this is for

  • SMEs that have outgrown spreadsheets and manual processes
  • Teams relying on a legacy WebForms/SQL Server system that’s slowing down
  • Organisations needing field apps that integrate properly with back-office data
  • Directors who want continuity and clear ownership of code and data

Typical outcomes

  • Fewer operational bottlenecks and less admin overhead
  • Faster systems (often by fixing SQL queries and data shape)
  • Better reporting and clearer “source of truth” data
  • Safer releases, documented handover, and support that doesn’t vanish

Not sure where to start?

If you have a legacy system, a manual process that’s slowing you down, or an idea for a new internal platform, we can scope it properly and decide the best route — modernise, rebuild, or iterate safely.

Common questions

Yes — I’m UK-based and work remotely with organisations across the UK. The London/Herts/Essex focus is simply where many of my clients are located.

Often, yes. A staged approach can reduce risk: performance fixes first, then incremental modernisation, then selective rebuild of the high-value areas.

I can offer secure managed hosting for systems I build and maintain — or I can advise you on the best alternative setup using your preferred provider.

Yes — offline-first workflows are common for field teams. The key is designing sync and conflict handling properly, and keeping the API stable.
