Engineering software and infrastructure that keeps working, rain or shine

RAIN OR SHINE LTD builds, modernises and maintains digital systems. We work across application development, cloud infrastructure, data engineering, quality assurance and ongoing technical support, with engineering practices designed for long-lived production systems.

What we do

A single engineering partner across the full delivery lifecycle

Our teams cover the work required to take a system from an idea to a maintained production service: discovery and technical analysis, architecture, implementation, testing, release engineering and long-term operation.

Engineering

Custom software development

Web applications, internal business systems, APIs and integrations built with modern, maintainable stacks and documented interfaces.

Platform

Cloud infrastructure

Infrastructure design, containerised workloads, automated deployment pipelines, environment separation and cost-aware scaling.

Data

Data engineering

Data models, pipelines, reporting layers and validation rules so that reporting and analytics work from consistent sources.

Quality

Quality assurance

Test strategy, automated regression suites, performance checks and release verification integrated into delivery.

Modernisation

System modernisation

Incremental replacement of ageing components, dependency upgrades, refactoring and migration planning with rollback paths.

Operations

Technical support

Monitoring, incident handling, corrective maintenance and planned improvement work after go-live.

Engineering approach

Deliberate architecture, small increments, visible progress

  • Understand before buildingEvery engagement starts with technical discovery: current systems, constraints, data flows and the outcomes the work must support.
  • Short delivery cyclesWork is split into increments that can be reviewed, tested and released, so direction can be adjusted without large rewrites.
  • Automation by defaultBuilds, tests and deployments are automated so that releases are repeatable and reversible.
  • Documentation as a deliverableArchitecture notes, runbooks and handover material are produced alongside the code, not afterwards.

Delivery process

Six stages from first conversation to maintained system

  1. 01

    Enquiry

    You describe the goal, context and constraints by email; we clarify scope and feasibility.

  2. 02

    Discovery

    Technical analysis of existing systems, data and integrations, resulting in a proposed approach.

  3. 03

    Planning

    Scope, milestones, team composition, assumptions and acceptance criteria are agreed in writing.

  4. 04

    Implementation

    Iterative development with code review, automated testing and regular demonstrations.

  5. 05

    Release

    Environment preparation, deployment automation, verification and handover documentation.

  6. 06

    Support

    Monitoring, maintenance and further increments under an agreed support arrangement.

Technology

Tooling chosen for maintainability, not novelty

Application layer

  • TypeScript and JavaScript
  • React front-ends
  • Node.js services
  • Python services

Data layer

  • Relational databases
  • Schema migrations
  • Reporting models
  • Batch and streaming pipelines

Infrastructure

  • Containerised workloads
  • Infrastructure as code
  • CI/CD pipelines
  • Observability and logging

Quality

  • Unit and integration tests
  • End-to-end automation
  • Static analysis
  • Performance testing

Engagement models

Three ways of working together

Model 01

Fixed-scope project

A defined deliverable with agreed milestones and acceptance criteria. Suitable when requirements are stable and documented.

Model 02

Dedicated team

Engineers working continuously on your roadmap with an agreed capacity, ceremonies and reporting cadence.

Model 03

Support and maintenance

Ongoing operation of an existing system: monitoring, fixes, dependency updates and incremental improvements.

Industries

Contexts our engineering practices suit

The following areas describe the types of technical problems our services are designed for.

  • Business process automation and internal tooling
  • Operations and logistics systems
  • Professional services and B2B platforms
  • Reporting, analytics and data consolidation
  • Integration between third-party systems
  • Legacy application modernisation

Quality and reliability

Reliability is a design decision, not a late-stage fix

We treat testing, observability and operational readiness as part of the definition of done. Every increment we release is expected to be deployable, monitored and reversible.

Code is reviewed before merge, automated checks run on every change, and infrastructure changes follow the same review path as application code.

Where a system carries risk, we document failure modes and recovery steps so that operational staff can act without relying on tribal knowledge.

Security and data handling

Careful handling of access, credentials and client data

Least privilege

Access to systems and data is limited to what a task requires and revoked when it ends.

Secret management

Credentials are stored in managed secret stores and never committed to source control.

Change traceability

Every change is recorded in version control with review history.

Data minimisation

We work with the smallest realistic data set needed, using anonymised data where possible.

Working with us

What collaboration looks like in practice

Cadence

Communication

A named point of contact, written summaries of decisions, and a regular review of progress against the agreed plan.

Reporting

Transparency

Open task tracking, visible backlog priorities and honest reporting when an estimate or assumption changes.

Handover

Ownership

Source code, infrastructure definitions and documentation belong to the client and are handed over in a usable state.

Knowledge

Continuity

Work is documented and shared across the team so that delivery does not depend on a single individual.

Common questions

Questions we are usually asked first

How does an engagement begin?
By email. Describe the goal and the current situation, and we respond with clarifying questions and a proposed next step.
Can you work with an existing codebase?
Yes. We begin with a technical review of the repository, dependencies, environments and deployment process before proposing changes.
Do you provide support after delivery?
Yes, under a separate agreed support arrangement covering monitoring, corrective maintenance and further increments.
Who owns the resulting code?
Ownership terms are agreed in the contract; our standard approach hands source code and infrastructure definitions to the client.
