Bespoke Android App Development

I develop bespoke Android apps for SMEs whose staff work on-site, on the road or in the field. The apps are usually paired with a web-based back office system, so your office team and field team stay in sync.

Typical clients include contractors, service engineers, inspection teams and other businesses in London, Hertfordshire and Essex who need something more tailored than a generic off-the-shelf app.

Typical Android apps I build

Common patterns I work on for clients:

  • Engineer job apps for capturing photos, notes and signatures on-site
  • Inspection and checklist apps for safety, compliance and quality audits
  • Apps for recording time on site, materials used and job status
  • Delivery and collection apps for tracking items, assets or equipment
  • Customer sign-off and proof-of-completion apps
  • Offline-first apps that still work with poor or intermittent signal
  • Apps that integrate tightly with your existing web system or database
  • Specialist tools tailored to niche workflows that generic apps don’t handle well

Designed to work in the real world

Field staff often work in environments where connectivity is patchy and time is limited. I design apps with that in mind:

  • Offline-first: capture data even with no signal, sync when back online
  • Simple, clear screens: minimal clutter so engineers can use the app quickly under pressure
  • Optimised photo handling: resize/compress images sensibly to balance quality and upload speed
  • Robust sync: APIs and background tasks that handle retries and conflicts gracefully

Tightly integrated with your back-office systems

A mobile app is only as useful as the data behind it. Most Android projects I work on are closely integrated with a bespoke web system or an existing SQL Server database:

  • Jobs, customers and sites pushed to devices automatically
  • Photos, notes and job outcomes synced back to the office in real time
  • Automatic updating of job statuses, timesheets and reports
  • Web-based dashboards so office staff can see what’s happening in the field

Technology stack

The exact tooling depends on your requirements, but typical approaches include:

  • Native Android development (e.g. Kotlin/Java) or .NET-based approaches where appropriate
  • RESTful APIs built with ASP.NET Core and secured appropriately
  • SQL Server back-end with performance-tuned queries and indexes
  • Background services for syncing data and processing photos
  • Optional use of AI for tasks like describing photos, extracting key details or suggesting next actions

Who this is for

This service is aimed at SMEs that:

  • Have staff working on-site or on the road who still rely on paper, WhatsApp or email
  • Need better visibility of what’s happening day to day in the field
  • Want to reduce manual re-keying of job data into office systems
  • Prefer to work with a developer who understands both web and mobile, not just one or the other

Considering an Android app for your field team?

If you think a mobile app could streamline how your engineers or site staff work, I can help you explore what’s realistic, what to avoid, and how it could integrate with systems you already rely on.
