The systems

Every capability we build on.

Seven disciplines and one team accountable for the seams between them. Each engagement is led by a senior engineer, across healthcare, travel, e-commerce, food delivery, fintech and professional services — sectors where an outage is an incident and a lost record is a liability.

Disciplines

  1. 01 APPLIED AI

    Applied AI and large language model integration

    We put large language models into production over client data — commercial APIs or self-hosted open-weight models — with retrieval evaluation, cost and latency controls and human-review checkpoints, so answers stay accurate, source-attributed and affordable to run.

    • OpenAI
    • Anthropic Claude
    • Open-weight models (Llama, Mistral)
    • RAG & vector retrieval
    • Embeddings
    • Agentic workflows
  2. 02 WEB & MOBILE

    Web and mobile application development

    We build custom web applications end to end and native or cross-platform mobile apps for Android and iOS, with a single team owning both surfaces so features, design and data stay consistent across every device.

    • Vue.js
    • React
    • TypeScript
    • Laravel
    • React Native
    • Flutter
    • Swift (iOS)
    • Kotlin (Android)
    • REST & GraphQL
  3. 03 SAAS PLATFORMS

    Multi-tenant SaaS platform engineering

    We build subscription platforms with securely isolated tenants on shared infrastructure — billing, usage metering and admin tooling designed in from the outset, so onboarding the hundredth tenant requires no re-architecture.

    • Laravel
    • Multi-tenant architecture
    • Role-based access control
    • Subscription billing & metering
    • Admin tooling
  4. 04 INTEGRATION & AUTOMATION

    Systems integration, CRM, ERP and process automation

    We connect systems that were never meant to interoperate — CRMs, ERPs, messaging channels and payment providers — and automate the processes across them, engineered to tolerate failure so outages never leave divergent records.

    • REST & GraphQL
    • Webhooks
    • OAuth
    • Meta Business platform
    • GoHighLevel
    • HubSpot
    • Zoho
    • SuiteCRM/SugarCRM
    • ERP
    • n8n
  5. 05 RESCUE & MODERNISATION

    Legacy modernisation, rescue and AI-codebase hardening

    We take over systems that have become costly or risky to change — including AI-generated ‘vibe-coded’ prototypes that demo well but are not production-ready — and modernise them by audit, upgrade and refactor while they stay in service.

    • Codebase audit
    • AI-generated code hardening
    • Framework & dependency upgrades
    • Regression tests
    • Refactoring
  6. 06 PERFORMANCE & SUPPORT

    Performance, reliability and managed maintenance

    Where systems slow under growth the cause is usually data-access patterns, not server size. We profile and fix at the query, index, caching or job level, then keep it monitored and maintained after launch.

    • Query & index optimisation
    • Caching strategy
    • Queue & background job architecture
    • Monitoring
    • Retained support
  7. 07 SEARCH & GROWTH

    Search, traffic and inbound lead generation

    A system nobody can find is not finished. We do the technical SEO, content architecture and answer-engine work that grows qualified traffic and turns it into inbound leads — measured on pipeline, not on rankings.

    • Technical SEO
    • Content architecture
    • Answer-engine optimisation
    • Structured data
    • Analytics & attribution
    • Conversion tracking

Team

Senior engineers, end to end.

Each engagement is led by a senior engineer who owns it from specification to handover, with additional capacity drawn from a vetted specialist network as scope requires. Working as a team is what provides continuity of delivery, independent code review, and the ability to add engineers where a timeline needs them.

  • Backend & platform

    PHP / Laravel, API and database architecture, multi-tenant systems and integrations.

  • Frontend

    Vue.js, React, TypeScript — responsive, accessible interfaces.

  • Mobile

    Android and iOS, native and cross-platform delivery.

  • AI / ML

    LLM integration, RAG pipelines and applied AI running in production.

  • DevOps & cloud

    AWS, Docker, CI/CD and containerised deployment.

  • QA & delivery

    Automated testing, release management, documentation and handover.
