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
- 01
Custom software development
Applications, internal tools and back-office systems built to a defined scope.
- 02
Web application development
Browser-based products with considered state handling, performance and accessibility.
- 03
Product design and UX
Flows, information structure and interface systems documented for engineering.
- 04
System architecture
Service boundaries, data ownership and integration contracts.
- 05
API and platform integrations
Connecting internal systems and third-party platforms with predictable contracts.
- 06
Cloud solutions
Environments, deployment pipelines, scaling behaviour and cost visibility.
- 07
Software modernization
Incremental replacement of legacy components without stopping the business.
- 08
Quality assurance
Test strategy across unit, integration and end-to-end levels.
- 09
Technical consulting
Review, options and written recommendations for a specific technical question.
- 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
- Stage 01
Discovery
Read the existing system, collect constraints, agree the problem being solved.
- Stage 02
Definition
Scope, sequencing and acceptance criteria written down and reviewed.
- Stage 03
Architecture
Interfaces, data ownership and failure behaviour decided before code.
- Stage 04
Design
Flows and interface structure prepared as engineering-ready specifications.
- Stage 05
Build
Short iterations, reviewed changes, automated checks on every merge.
- Stage 06
Verification
Functional, integration and regression testing against the agreed criteria.
- Stage 07
Release
Repeatable deployment, rollback path, monitoring in place before launch.
- 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.

Descriptive figures about how we work — not performance claims
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.
