Technology / Chosen with purpose

The right tools.
For your system.

A stack is a set of decisions. We choose around your product, your constraints and the people who will operate it.

Explore the layers

The starting point

Make the important things reliable.
Keep the rest as simple as the problem allows.

How we make decisions
01 / Frontend

Web experience

Interfaces that make the product understandable.

TypeScriptReactNext.jsTailwind CSS

Rendering, navigation and state management depend on the experience. A public website has different needs from an authenticated workspace with complex interactions.

Decisions we work through
  • Rendering strategy and page performance
  • Accessible components and keyboard behaviour
  • Loading, empty, error and recovery states
02 / Mobile

In people’s hands

Shared foundations, with care for the device.

React NativeExpoiOSAndroid

A mobile product has to account for unreliable connectivity, permissions, notifications and platform conventions. The architecture should reflect how and where people use it.

Decisions we work through
  • Offline behaviour and synchronisation
  • Platform capabilities and permissions
  • Distribution, updates and crash reporting
03 / Backend

Business logic

Clear contracts between the experience and the system.

Node.jsPythonFastAPIGraphQL

APIs express business operations, enforce permissions and validate input. Longer-running work may belong in a background job, with retries and progress that can be observed.

Decisions we work through
  • API contracts and authentication boundaries
  • Idempotent operations and safe retries
  • Synchronous requests versus background work
04 / Data

A dependable record

Storage chosen around the shape and value of the data.

PostgreSQLRedisMongoDBElasticsearch

Use a transactional store where records must change together; add caches or search indexes for a specific need. Decide which system owns each fact and how derived data is rebuilt.

Decisions we work through
  • Transactions, constraints and consistency
  • Search, caching and invalidation
  • Migrations, backups and retention
05 / Infrastructure

A place to run

An operating environment the team can understand.

AWSGoogle CloudVercelKubernetes

Hosting choices follow the workload, security boundaries, regional requirements and operating capacity. A managed service may be a better fit than infrastructure that needs a dedicated platform team.

Decisions we work through
  • Network boundaries and access controls
  • Availability, regional placement and cost
  • Managed services versus custom operations
06 / Delivery

A repeatable release

Changes that can be checked, deployed and traced.

DockerTerraformCI/CD

Version the application and environment configuration, run meaningful checks, and make release and rollback steps explicit. Monitoring should help the team understand what changed.

Decisions we work through
  • Builds, automated checks and deployment gates
  • Infrastructure as code and secret management
  • Logs, metrics, alerts and recovery procedures

07 / How the pieces connect

A system,
considered together.

A typical web product connects these layers. The exact services and boundaries are agreed during architecture.

01 / Experience

Interface

Web or mobile
Interaction & state

02 / Behaviour

Application

APIs & permissions
Business workflows

03 / Records

Data

Durable records
Search & caching

04 / Continuity

Operations

Deploy & observe
Recover & improve

The quality of the connections matters as much as the individual tools: clear contracts, tested failure paths and ownership across the whole system.

Start with what
you already have.

We can review the architecture, identify constraints and plan a focused improvement. A useful change does not have to begin with a rewrite.
