An architecture should explain how the product will work and what happens when part of it fails. EidenTech can help plan a new application or review an existing system before a consequential change. The starting point is your business process, expected use, and operating team. We document assumptions and tradeoffs so the implementation has an understandable foundation rather than a diagram of fashionable technologies.
How we approach your project
Translate product needs into system responsibilities
Start with the journeys the software must complete: a retailer publishes products, a customer submits an order, or a team reviews a reconciliation exception. Identify which information each action reads and changes, who may perform it, and what counts as completion. We separate business rules from interface choices and external dependencies. Expected traffic, response needs, data sensitivity, and recovery expectations become explicit requirements. A requirement such as “scale later” is turned into assumptions the team can assess instead of an unlimited infrastructure promise.
Choose boundaries your team can operate
Define the responsibilities of the frontend, application services, persistence, background work, and third-party connections. A modular application may be a practical starting point when one team releases the product together. Separate services may suit independent workloads or ownership, but add deployment and communication responsibilities. We review where transactions need to stay together and where an asynchronous handoff is acceptable. The proposed design explains these choices, including what would justify changing the boundary as the product grows.
Make data flows and failure paths visible
A successful diagram needs a failed version alongside it. Trace what happens when an external API times out, an event arrives twice, or a worker stops after partially completing a job. Determine the source of truth, retry responsibility, and state a user sees while work is pending. Access checks belong at the backend boundary, and confidential configuration stays outside browser code. Where an action cannot simply be reversed, we discuss reconciliation or an explicit recovery operation instead of assuming that retrying always fixes it.
Test the decisions that carry the most uncertainty
Some choices need evidence before the full implementation begins. A small technical investigation can examine an unfamiliar provider API, a demanding query, or a background-processing approach with representative data. We agree the question being tested and the evidence needed to answer it. Capacity estimates are based on stated workloads rather than guarantees about unknown traffic. A result may support the proposed design, narrow its scope, or show that an integration assumption must change before the team commits further effort.
Leave a plan that survives the handover
Document the system context, component responsibilities, data flows, deployment assumptions, and important design decisions in a format the implementing team can maintain. Identify operating owners for alerts, migrations, backups, and integration credentials. The release plan should include how changes can be introduced without losing important records or confusing users. We distinguish decisions needed now from decisions deferred until there is evidence. Architecture review can then focus on changing requirements and observed bottlenecks instead of repeatedly rediscovering why the system was arranged this way.
What we can deliver
We agree the requirements and responsibilities before development begins. Your project scope can include:
- A requirements and assumptions brief tied to real product journeys and operating needs.
- System context, component boundaries, data flows, and documented architecture decisions.
- An agreed approach to permissions, failure handling, background work, and recovery.
- Focused technical investigations for material uncertainties, with conclusions and remaining questions.
- Implementation priorities and an operating handover appropriate to the agreed scope.
Technology choices for your requirements
The stack follows your integrations, operating model, and maintenance needs. These are options to review during discovery, rather than a fixed stack promised for every project.
- Architecture decision records and system context or sequence diagrams
- Relational persistence, application APIs, and durable workers where the workflow requires them
- Deployment and observability tools selected for the implementing team
Planning questions, answered
Can you review an architecture someone else designed?
Yes. Share the product requirements, diagrams, implementation context, and the decision causing concern. We can scope a review of boundaries, data ownership, operational assumptions, and specific risks without assuming the entire system needs replacement.
Do we need microservices from the beginning?
Not necessarily. We review workload differences, team ownership, release independence, and operational capacity. A modular application can be a useful first design; distributed services should address a concrete requirement and include their additional operating responsibilities.
What do you need for a useful system design brief?
Bring the principal users, important journeys, existing integrations, expected usage, sensitive data categories, and known constraints. If these are incomplete, the first scope can clarify assumptions and identify which decisions need evidence before development.
Can architecture planning include an existing database and APIs?
Yes. We review their contracts, access rules, limitations, and ownership. The design can keep useful components and identify the migration or integration work needed for the new workflow, rather than treating every project as a fresh build.
