Experience

Giveaway campaigns for a WordPress shop

A shop wanted interactive giveaways to engage customers and grow its audience — without heavy plugins that slow the site down.

  • Approach. A standalone app around the shop: a WordPress plugin to configure campaigns from the shop's admin, and a fast frontend with public entry pages and a private, logged-in area using the shop's own customer accounts.
  • Result. Campaigns entered in seconds with the accounts customers already had — fast, independent of the shop's theme and plugins, managed from the shop's admin.

Experience

Online shops built on WordPress & WooCommerce

Online shops that sell — catalogue, checkout and payments working as one, without a developer on call for every change.

  • Approach. WordPress & WooCommerce builds: catalogue structure, payment integration and shop customisation — plus the upkeep that keeps a shop running after launch.
  • Result. Shops with integrated payments and manageable catalogues — knowledge that also makes migrations off WordPress cost-effective.

Experience

Server maintenance & modernisation

Ageing servers and platforms — outdated stacks, unpatched software, rising costs, and updates nobody dared to touch.

  • Approach. Step-by-step migrations, legacy refactoring where migration does not pay, architectures chosen for lower running costs — security hardened along the way.
  • Result. Overdue systems modernised without losing what worked — on simpler, hardened foundations with smaller, more predictable bills.

Experience

Training business operations platform

Courses, quoting, payments and learner communication lived across scattered tools and spreadsheets — no single operational view.

  • Approach. One modular system: bookings, Stripe & GoCardless payments, email notifications, and an interactive flow that unlocks course parts as learners progress.
  • Result. The full operational lifecycle — bookings, payments, content and learner progress — in one platform.
