What I build

Custom software that
earns its keep.

Practical software for growing UK businesses tired of disconnected apps and spreadsheets passed around on email — built, hosted, and supported by one senior developer.

Service 01 · Portals

Customer & staff portals.

Secure login areas where customers, suppliers, staff, or partners can self-serve — share documents, track jobs, approve work, and see status — without another email chain.

  • Client dashboards & project areas

    Customers log in and see only what's theirs, with the right level of detail.

  • Document sharing & approvals

    Upload, version, sign off — no more attachments lost in inboxes.

  • Role-based access & audit trails

    Permissions you can explain, and a log of who did what, when.

Service 02 · Internal tools

Internal tools & workflow systems.

Replace fragile spreadsheets and inbox-shaped processes with friendly internal tools shaped around how your team actually works — and only your team.

  • Job tracking & operations dashboards

    Move jobs through stages without anyone shouting across the office.

  • Admin tools staff can trust

    Clear interfaces that don't need training each new starter.

  • Reporting that needs no cleanup

    Numbers you can hand to an accountant — or a board — without a panic.

Service 03 · Integrations

Integrations between tools you already pay for.

Connect Xero, Stripe, CRMs, and booking tools so data flows once, automatically, instead of being typed in twice. Smaller, surgical builds that quietly save hours every week.

  • Xero, Stripe, CRMs & booking tools

    The usual suspects, properly connected, with sensible error handling.

  • APIs, webhooks & one-off data imports

    Migrating off something old? I'll bring the data over cleanly.

  • Monitoring & alerting

    If something stops talking, you find out — before the customer does.

How it's priced

Three stages, no surprises.

Discovery first. Fixed price after. The bill matches the quote — every time.

slow, manual, or scary.
