Catalogue

Twelve services, one studio.

Each service below describes what it includes, the business situation it usually addresses, how the work is approached, and the practical value it may provide. Nothing here is promised as a guaranteed outcome.

Service 01 / 12

Custom software development

What it includes

New applications built from a written specification: data models, business logic, user interfaces, background processes and administrative tooling.

Business need

Organisations whose operational processes have outgrown spreadsheets, off-the-shelf tools or a mesh of manual work.

How we approach it

We start with a discovery phase to model the workflow, then build in iterative slices with weekly demos. Each release adds working functionality, not a fragment.

Practical value

A single, well-modelled application that fits the business exactly and can be maintained and extended over years.

Service 02 / 12

Corporate website development

What it includes

Marketing sites, corporate portals and content platforms — engineered for performance, accessibility and search.

Business need

Companies whose current site was assembled ad-hoc, is slow to update, or does not reflect the operation behind it.

How we approach it

We design an information architecture, produce a component system, and build the site on a modern framework with a content model that non-engineers can operate.

Practical value

A site that loads quickly, remains accessible on any device, and can be updated without an engineer for every change.

Service 03 / 12

Web application development

What it includes

Customer portals, dashboards, internal tools, admin consoles, self-service platforms and any authenticated web software with real business logic.

Business need

Teams that need software their users open every day — where usability, correctness and predictability matter more than novelty.

How we approach it

React and TypeScript on the frontend, a considered backend behind it, real authentication and role model, and a design system built to survive contact with real users.

Practical value

A durable application that the team can actually rely on to run the work, not a demo that has to be babysat.

Service 04 / 12

Product interface development

What it includes

Design-led interface work for digital products: interaction design, prototyping, component libraries and production-ready front-end implementation.

Business need

Product teams that have a working backend and a rough idea, and need the interface layer built at a professional standard.

How we approach it

We work in short cycles with your product and design people, prototype in code where possible, and finish with a maintainable component set documented for internal use.

Practical value

A product interface that is coherent, accessible and easy for other engineers to extend.

Service 05 / 12

API development & integration

What it includes

Public and private APIs, service-to-service integrations, event-driven pipelines and connectors between third-party systems.

Business need

Businesses whose value comes from making several systems co-operate — ERPs, CRMs, billing platforms, payment providers, logistics tools.

How we approach it

REST, GraphQL or gRPC as appropriate, versioned contracts, defensive error handling, idempotent operations, and end-to-end observability.

Practical value

Integrations that keep working when a third party changes their API, and that are safe to modify without unexpected side effects.

Service 06 / 12

Legacy system modernisation

What it includes

Refactoring, incremental rewrites, database migrations, cloud migration and the gradual replacement of aging applications.

Business need

Organisations running critical software that has become expensive to change, hard to hire for, or difficult to operate safely.

How we approach it

We prefer strangler-pattern rewrites over big-bang replacements: introducing new services alongside the legacy system and moving traffic across in controlled steps.

Practical value

A migration path that keeps the business running throughout, without a moment where everything changes at once.

Service 07 / 12

Cloud architecture

What it includes

Cloud environment design across AWS, GCP, Azure and hybrid deployments, described in infrastructure-as-code and structured for cost predictability.

Business need

Teams moving to the cloud, consolidating multiple accounts, or trying to understand and control a cloud bill that has become unpredictable.

How we approach it

Environments defined in Terraform or equivalent, clear separation between staging and production, network and identity policies written down, and a documented deployment model.

Practical value

Infrastructure that can be rebuilt from source, understood by a new engineer within a day, and reasoned about for cost.

Service 08 / 12

DevOps & deployment workflows

What it includes

CI/CD pipelines, container orchestration, environment automation, observability, incident response and on-call setup.

Business need

Engineering teams whose deployments have become slow, manual or fragile — or who have never had a proper delivery pipeline in place.

How we approach it

We work with existing tools where possible (GitHub Actions, GitLab, ArgoCD, Kubernetes), and prefer boring, well-documented pipelines over bespoke automation.

Practical value

Deployments that happen many times a day without ceremony, and that can be recovered from without waking anyone up.

Service 09 / 12

Technical consulting

What it includes

Architecture reviews, technology selection, second opinions on RFPs, due diligence on inherited codebases and short focused engagements to unblock a specific decision.

Business need

Founders, CTOs and product leaders who need an outside engineering perspective on a decision they have to justify internally.

How we approach it

A short discovery followed by a written report and a working session. We describe options, trade-offs and recommendations in plain language, with the technical reasoning attached.

Practical value

A defensible technical decision backed by written analysis you can share with your team, board or investors.

Service 10 / 12

Software maintenance

What it includes

Ongoing support, bug fixing, dependency upgrades, minor enhancements and operational responsibility for existing systems.

Business need

Organisations running software they depend on but do not have the internal team to maintain — or who need to give their existing team room to focus on new work.

How we approach it

A service-level agreement that fits the business, a shared backlog, monthly reporting on what changed, and a documented handover so nobody is trapped in the arrangement.

Practical value

Software that continues to evolve safely over years, without accumulating the kind of debt that eventually forces a rewrite.

Service 11 / 12

Performance optimisation

What it includes

Front-end performance work, database query analysis, caching strategy, service tuning and load testing.

Business need

Applications that were fast at launch and have gradually become slow — or that are hitting limits at higher scale than they were designed for.

How we approach it

Measurement first: real profiling under representative load, then targeted changes with before/after evidence. No speculative rewrites.

Practical value

Concrete, quantified improvements in Core Web Vitals, response times or throughput — and a clear picture of what to work on next.

Service 12 / 12

Security-focused engineering

What it includes

Threat modelling, secure coding reviews, authentication and authorisation design, secrets management, data protection and pre-audit remediation.

Business need

Teams preparing for a security review, handling regulated data, or aware that their current security posture has drifted from where it should be.

How we approach it

We work against recognised references — OWASP ASVS, CIS benchmarks, ISO 27001 controls — and produce written findings with concrete remediation, prioritised by impact.

Practical value

A meaningfully smaller attack surface and a written record of what was reviewed, what was changed, and what remains.
