# Solution Architecture

The right architecture is the foundation of everything. We design systems that scale, survive, and cost the right amount.

What we offer

## Architecture that lasts

Good architecture decisions made early save enormous time and money later. We help you make the
right choices — between microservices and monolith, cloud-native and hybrid, synchronous and
event-driven — based on your actual scale and team size, not trends.

We work with both greenfield projects and existing systems that have grown beyond their original
design. For legacy systems, we produce clear architectural roadmaps — incremental steps to
modernise without a costly rewrite.

We deliver architecture decision records (ADRs), component diagrams, data flow documentation, and
hands-on guidance during implementation. Architecture is not just a diagram — it is a set of
decisions your team can execute.

### Architecture design

Component design, data modelling, API contracts, and technology selection tailored to
your constraints.

### Legacy modernisation

Incremental modernisation roadmaps — strangler fig, modular monolith, and event-driven
patterns.

### Architecture review

Independent review of your existing architecture — identify technical debt and risk
before it bites.

### Hands-on guidance

We work alongside your team during implementation — not just hand over a document and
disappear.

Our approach

## Decisions, not diagrams

Architecture engagement produces usable artefacts and shared understanding — not shelfware.

1

### Context & constraints

We understand your business drivers, team skills, compliance needs, and budget before
drawing a single box.

2

### Options & trade-offs

We present 2–3 architectural options with explicit trade-offs — so you make informed
decisions, not guesses.

3

### Design & documentation

ADRs, C4 diagrams, API specs, and data flow documentation that your team can actually
use.

4

### Implementation support

Architecture reviews during development to catch drift early and answer questions as they
arise.

Case study

## Microservices migration for a rapidly scaling HR platform

An HR SaaS platform had outgrown its monolithic Rails application. Deployment took 45 minutes, a
single bug could take down the whole product, and the team couldn't scale independently. We designed
a domain-driven microservices architecture with an incremental migration plan.

Over 12 months, 8 bounded contexts were extracted from the monolith. Deployment time dropped to 4
minutes per service. The platform now handles 10× the original traffic with the same team size.

✓ 45 min → 4 min deploys
✓ 10× traffic capacity
✓ 8 services extracted
✓ Zero big-bang rewrite
