Software engineering studio
Systems
built to be
maintained
APPLE AND OAT LTD designs, builds and maintains software for organisations that depend on their digital systems every working day.
Our work spans custom applications, cloud platforms, integrations, data infrastructure and long-term technical support — delivered with documentation, tests and an explicit account of the decisions behind each system.
01 — Overview
An engineering
company, not
a template shop
We work with organisations that need software written specifically for their processes. That usually means understanding an existing way of working in detail, then expressing it in a system that is faster, clearer and easier to change than what came before.
Engagements vary in size. Some are a single application built from scratch; others are an integration layer, a migration off ageing technology, or continuing engineering support alongside an internal team. In every case the aim is the same: a system that behaves predictably and can be maintained without guesswork.
Core capabilities
02 — Technology
- Application engineering
- Server-side services, web clients and background processing built as one coherent system rather than a set of disconnected parts.
- Cloud and platform work
- Environments, deployment pipelines and infrastructure definitions that make releases repeatable and reversible.
- Interfaces and integration
- APIs, message flows and adapters that let existing tools exchange data without brittle manual steps.
- Data engineering
- Storage models, pipelines and reporting layers that keep operational and analytical data consistent.
- Engineering for security
- Threat-aware design, access control, secrets handling and dependency hygiene applied during development.
- Verification and support
- Automated tests, review practices, observability and ongoing maintenance after the first release.

04 — Delivery
How a project moves from question to running system
- Step 01
Discovery
We map the problem, the people involved and the systems already in place before proposing any technical direction.
- Step 02
Definition
Requirements are written down as concrete outcomes, constraints and acceptance criteria that can be checked later.
- Step 03
Architecture
We choose a structure that fits the load, the team and the maintenance window, and we document the trade-offs it carries.
- Step 04
Iterative build
Work is delivered in short increments so behaviour can be reviewed early and direction adjusted while change is cheap.
- Step 05
Verification
Automated and exploratory testing run alongside development, together with performance and security checks.
- Step 06
Release and care
Deployment is automated and monitored, and the system is supported, patched and improved after go-live.
05 — Expertise
Technology we
work with
Tools are chosen for the problem, not for novelty. We favour widely supported, well-documented technology so that a system remains hireable, patchable and understandable years after it ships.
- Languages
- TypeScript, JavaScript, Python, Java, Go, SQL
- Front end
- React, modern web standards, design systems, accessibility
- Back end
- Node.js, REST and GraphQL services, event-driven processing
- Data
- PostgreSQL, relational modelling, warehousing, pipelines, reporting
- Cloud
- Containers, infrastructure as code, CI/CD, observability
- Practice
- Automated testing, code review, documentation, version control
06 — Context
Problems
we are
asked to solve
- Operations-heavy businesses
- Manual handovers between spreadsheets, email and legacy tools that slow work down and hide errors until late.
- Digital products
- Interfaces that grew feature by feature and now need a coherent structure, faster loading and clearer navigation.
- Service organisations
- Customer records spread across separate systems, making a single reliable view of activity difficult to produce.
- Data-driven teams
- Reporting built on fragile exports, where numbers disagree between sources and nobody can trace the difference.
07 — Security & quality
Quality is a
process, not a
final review
Security considerations enter at design time. We identify what data a system handles, who should reach it, and what happens if a component is compromised. Access control, secret storage, input validation and dependency updates are part of ordinary engineering work rather than a later hardening phase.
Quality follows the same logic. Automated tests are written alongside features, changes pass review before they merge, and deployments are observable so problems surface quickly. When something does go wrong, logging and monitoring are there to explain it instead of leaving the team to guess.
We describe risks in plain terms and avoid guarantees that no engineering practice can honestly make. What we commit to is method, transparency and correction.
Working together
08 — Collaboration
Written decisions
Architecture choices, trade-offs and open questions are recorded so the reasoning survives beyond a single conversation.
Small, visible increments
Progress is shown in working software instead of status reports, which keeps feedback loops short.
One shared backlog
Client and engineering priorities live in the same place, so scope changes are explicit rather than implied.
Handover by default
Code, infrastructure definitions and documentation are structured so another team could pick the work up.
09 — Reasons
Why
organisations
choose this
approach
The reasoning is visible
Every significant decision has a written rationale. Stakeholders can see why a structure was chosen, what it costs and what it rules out.
Systems stay changeable
Tests, clear boundaries and documentation keep the cost of the next change reasonable, which matters far more than the speed of the first release.
Communication is direct
Progress, blockers and risks are reported as they are. Estimates are presented as ranges with the assumptions that produced them.
Ownership transfers cleanly
Source code, infrastructure configuration and operational notes are organised so an internal team can take over whenever that becomes the right step.
