00Technology practice

Software built
to be maintained.

JER Legal is a technology practice. We design, build, integrate and maintain software systems for organisations that want engineering work handled with structure, documentation and a clear scope.

01IT capabilities

Four practices,
one delivery model

Engineering
Application code, services, data models and automated checks written to be read by the next engineer.
Design
Interface structure, interaction detail and design systems that hold together as a product grows.
Architecture
Boundaries, contracts and data flow decided deliberately and written down before implementation.
Operations
Environments, deployment paths, observability and the routine work that keeps software running.

02Core service categories

  1. 01

    Custom software development

    Applications, internal tools and back-office systems built to a defined scope.

  2. 02

    Web application development

    Browser-based products with considered state handling, performance and accessibility.

  3. 03

    Product design and UX

    Flows, information structure and interface systems documented for engineering.

  4. 04

    System architecture

    Service boundaries, data ownership and integration contracts.

  5. 05

    API and platform integrations

    Connecting internal systems and third-party platforms with predictable contracts.

  6. 06

    Cloud solutions

    Environments, deployment pipelines, scaling behaviour and cost visibility.

  7. 07

    Software modernization

    Incremental replacement of legacy components without stopping the business.

  8. 08

    Quality assurance

    Test strategy across unit, integration and end-to-end levels.

  9. 09

    Technical consulting

    Review, options and written recommendations for a specific technical question.

  10. 10

    Maintenance and support

    Dependency upkeep, fixes and small changes after release.

03Company approach

Decide first, build second

Most software problems are decision problems that were never written down. Before implementation begins we agree what the system must do, where its boundaries sit, what data it owns and how it behaves when something fails.

That record travels with the work. It shapes the estimates, the tests and the handover, and it means a change requested six months later can be assessed against something concrete rather than reconstructed from memory.

04Technology expertise

Languages

TypeScript, JavaScript, Python, Go, SQL

Frontend

React, component systems, design tokens, accessibility patterns

Backend

REST and event-driven services, background processing, caching

Data

Relational modelling, migrations, analytics pipelines, search

Platform

Containers, CI/CD, infrastructure as code, observability

Integration

Webhooks, message queues, third-party APIs, identity providers

05Development process

Eight stages

  1. Stage 01

    Discovery

    Read the existing system, collect constraints, agree the problem being solved.

  2. Stage 02

    Definition

    Scope, sequencing and acceptance criteria written down and reviewed.

  3. Stage 03

    Architecture

    Interfaces, data ownership and failure behaviour decided before code.

  4. Stage 04

    Design

    Flows and interface structure prepared as engineering-ready specifications.

  5. Stage 05

    Build

    Short iterations, reviewed changes, automated checks on every merge.

  6. Stage 06

    Verification

    Functional, integration and regression testing against the agreed criteria.

  7. Stage 07

    Release

    Repeatable deployment, rollback path, monitoring in place before launch.

  8. Stage 08

    Care

    Maintenance, dependency updates and planned change after handover.

06Situations we support

Where this work
usually starts

A product that outgrew its first build
Early code that worked at small scale now blocks changes and needs restructuring.
Systems that do not talk to each other
Data re-entered by hand between tools that were never integrated.
Manual internal processes
Repeated spreadsheet work that can be modelled as software.
Legacy platforms
Software still in service but expensive to change or unsupported.
Teams without in-house engineering
Organisations that need a structured technical counterpart.
Products approaching a scale change
Growth that exposes architectural limits before it breaks them.

07Operating principles

Security, reliability, maintainability

Security
Least-privilege access, validated input, encrypted transport, secrets kept out of source control and dependency review as routine work.
Reliability
Explicit failure behaviour, health checks, structured logging and rollback paths defined before a release, not after an incident.
Maintainability
Readable code, small modules, typed interfaces, automated tests and written decisions so the next change is cheaper than the last.

09Why a structured partner

Four reasons

Written decisions
Architecture and scope choices are recorded, so nothing depends on recollection.
One process
The same delivery sequence applies to a small change and a full build.
Handover by default
Code, environments and documentation are prepared to be taken over.
Scope discipline
Work is agreed before it starts and changes are re-agreed, not absorbed silently.

Written enquiries are the fastest route. A short description of the system, the outcome you need and any deadline is enough for a first reply.
