Service · Flagship

Custom software
that runs for years.

Internal tools, B2B SaaS, customer portals, citizen-facing government platforms, operational backbones. AI integration, data tooling, and cloud architecture are part of the build where they earn their place - not separate buckets to upsell.

What you get

Built to last, not just to launch.

  • 01

    Production-grade backends and web surfaces - internal tools, B2B SaaS, customer portals, citizen-facing systems.

  • 02

    AI integration, data tooling, and ML workflows embedded where they earn their place against a deterministic alternative.

  • 03

    Deep integrations into SAP, MES, payment switches, identity stacks, and legacy systems - the real cost centre of any custom build.

  • 04

    Cloud architecture, observability, and CI/CD baked in from the foundation sprint - not bolted on at the end.

  • 05

    Performance, accessibility (WCAG 2.1 AA), and security as a default, not a phase-two concern.

  • 06

    Handover with documentation, runbooks, and an optional retainer for run support and incremental delivery.

How we deliver

Four phases, no black-box.

Each phase produces a written artefact, so you and procurement always know what's next.

  1. Phase 101

    Discovery & architecture

    2-3 weeks. UX research, technical architecture, data model, integration map. Output: written technical strategy and a phased delivery plan with milestones.

  2. Phase 202

    Foundation sprint

    First 2-3 weeks of build. Repo, CI/CD, auth, base design system, observability - the boring parts done right so subsequent sprints move fast.

  3. Phase 303

    Feature sprints

    2-week cadence, demo every Friday. End-of-sprint review with your product owner. Written change log per release. Staging environment always reflects main.

  4. Phase 404

    Launch & stabilisation

    Cut-over plan, smoke-test playbook, on-call rotation for first 30 days, then handover or retainer for ongoing delivery.
