Enterprise architecture — systems that last.
Architecture as a strategic lever, not a documentation exercise. We design systems that absorb growth, uncertainty, and audit.
Coda Solutions is a Casablanca-based IT engineering firm that designs the architecture of mission-critical systems for banks, insurers, large groups and public institutions in Morocco. We define realistic target architectures — microservices, event-driven, legacy integration — and stay until they run in production, taking Bank Al-Maghrib requirements, law 09-08 and law 05-20 into account.
Areas of expertise
From conception to delivery
Reference architectures
Designing your organisation's technical standards: integration patterns, decision guides, ADRs (Architecture Decision Records).
Microservices migration
Reasoned monolith decomposition: bounded context identification, progressive extraction, coexistence management.
Event-driven architecture
EDA, CQRS, Event Sourcing. Decoupled systems that absorb load and evolve independently.
Technical debt assessment
Precise mapping of existing debt, prioritisation by impact and risk, measurable reduction plan over 12 to 24 months.
API Management & integration
API design (REST, GraphQL, AsyncAPI), versioning, gateway, catalogue, living documentation.
Legacy modernisation
Strangler fig, ports and adapters, progressive encapsulation. Modernise without rewriting everything — and without service interruption.

How an engagement runs
Four stages, a deliverable at each
Diagnostic
Map of the existing estate, regulatory constraints, breaking points. A factual assessment, not a box-ticking audit.
Target architecture
Target architecture, documented decisions (ADRs) and a migration path split into reversible steps.
Guided delivery
Our architects stay with the delivery teams, internal or external, through the first production releases.
Handover
Standards, documentation and governance handed to your teams, so the architecture holds without us.

Frequently asked questions
What is the difference between an enterprise architect and a solution architect?
The enterprise architect works at the scale of the whole estate: map, standards, multi-year path. The solution architect designs one specific system within that frame. We do both, and above all we connect them: an enterprise architecture that never reaches real systems remains a document.
Should we move to microservices?
Not necessarily. Microservices solve team and release-cadence problems at the cost of real operational complexity. For many systems, a well-structured modular monolith is enough. We recommend microservices when domains need to evolve or scale independently — and we justify it in writing.
How do you build Bank Al-Maghrib requirements into the architecture?
By translating them into verifiable technical requirements at design time: environment separation, access and operation traceability, tested business continuity, controlled outsourcing and cloud use. Each requirement is linked to an architecture decision, which makes discussions with internal control and the regulator easier.
How does an engagement with Coda Solutions start?
With a 30-minute first conversation with a senior engineer from our Casablanca team, not a salesperson. If the need is confirmed, we scope it, then propose an engagement model: fixed scope, embedded team or architecture advisory. You know who will work on your project before you sign.
