How we engage

From a single discovery sprint to a multi-year platform programme — with the same standards of engineering either way.

  • Custom Software Development

    Bespoke platforms built around how your organisation actually works, not around a vendor's roadmap.

  • Web Development

    Fast, accessible, SEO-ready web applications and corporate platforms built on modern React.

  • Mobile Apps

    Native-quality Android and iOS applications, including offline-first field tools for low-connectivity environments.

  • Cloud & DevOps

    Cloud architecture, containerisation, CI/CD and observability — with the cost model designed in.

  • Cyber Security

    Security assessment, hardening, secure development and incident readiness for business-critical systems.

  • Security & Compliance Auditing

    Independent audit of systems, data and processes, with a compliance report, remediation plan and retest.

  • API Integration

    Connecting the systems you already run — payment providers, mobile money, ERPs, government platforms.

  • UI/UX Design

    Research-led product design and design systems that survive contact with real users and real data.

  • AI Consulting

    Identifying where AI creates measurable value in your operation — and where it does not.

  • System Integration

    Making independently-built systems behave as one, with clear ownership of data and process.

  • Legacy Modernization

    Moving off systems that still work but can no longer change — without stopping the business.

Why WZ Solutions

Engineering discipline, not just delivery

Anyone can produce a demo. What separates a system that survives its second year is the discipline applied while building it.

  • Engineering, not assembly

    We design the data model and architecture around your operation. No template stretched to fit a business it was never built for.

  • Built for our conditions

    Offline-first field capture, low-bandwidth interfaces and mobile money integration — designed for how work actually happens here.

  • Measurable non-functionals

    Uptime, latency, accessibility and performance budgets are written into the contract and enforced in the pipeline.

  • You own what we build

    Source code, infrastructure definitions and documentation are yours. No lock-in to us as a vendor.

  • Security from sprint one

    Threat modelling, least-privilege access and encryption designed in — not retrofitted after a penetration test.

  • Support that knows your system

    A named engineer, defined response times, and written root cause analysis after every incident.

How we work

Seven steps from idea to scale

The same delivery process on every engagement — so you always know what happens next, what you receive, and who is accountable.

  • 01

    Discover

    Workshops with the people who do the work. We map the current process, quantify the problem and agree what success will be measured against before anyone writes code.

    • Process map
    • Scope and risk register
    • Success metrics
  • 02

    Design

    Architecture decisions recorded with their trade-offs, interface prototypes tested against real data volumes, and a design system implemented in code.

    • Architecture decision records
    • Interactive prototype
    • Design system
  • 03

    Develop

    Two-week increments, every one deployed to a shared environment. Code review and automated tests are part of the definition of done, not a later phase.

    • Working software each sprint
    • Test suite
    • Sprint demos
  • 04

    Test

    Functional, integration, performance, accessibility and security testing — with acceptance criteria agreed up front and verified by your team, not just ours.

    • Test reports
    • UAT sign-off
    • Performance and a11y results
  • 05

    Deploy

    Automated pipelines promote through environments. Migrations run with validation and reconciliation, and every release has a rollback that has been rehearsed.

    • CI/CD pipeline
    • Migration and cutover plan
    • Rollback procedure
  • 06

    Support

    Defined response times, monitored infrastructure, and a named engineer who knows your system. Incidents get a written root cause, not just a fix.

    • SLA agreement
    • Monitoring and alerting
    • Root cause reports
  • 07

    Scale

    Capacity reviewed against real usage, bottlenecks addressed before they bite, and the roadmap revisited quarterly with your team.

    • Capacity review
    • Performance tuning
    • Quarterly roadmap

Systems in production

Selected engagements, described by the problem they solved rather than the technology used.

In their words

What clients tell us

Quotes are anonymised at our clients' request until each reference is formally approved.

  • They spent the first two weeks understanding how our billing actually worked before proposing anything. That is not what we were used to from software vendors.

    Operations Director

    Regional water utility

  • Every sprint ended with something we could open and click. We knew where the project stood at all times, which made the budget conversations straightforward.

    Chief Financial Officer

    Multi-site services group

  • The handover included documentation our own engineers could work from. Six months on, they are extending the system without us calling anyone.

    Head of IT

    Distribution company

  • Innovation

    We continuously look for new ways to solve problems through technology.

  • Excellence

    We deliver solutions to high standards of quality, performance and reliability.

  • Integrity

    We act with ethics, transparency and accountability in every relationship.

  • Security

    Protecting information and privacy is built into every solution we develop.

  • Client Focus

    We understand what clients need and build solutions that produce concrete results.

  • Continuous Learning

    We invest permanently in knowledge, innovation and technological progress.

  • Impact

    We build technology that contributes to organisational growth and to economic and social development.
