Solutions Architect

Functional Requirements

Perché: Lets you reconcile conflicting requirements from different stakeholders and trace each one to a component, so scope disputes are settled on paper.

Non-Functional Requirements

Perché: Lets you resolve trade-offs between targets, such as accepting higher latency to meet a security constraint, and get the sponsor to agree.

API Design Patterns

Perché: Lets you place an API gateway and define a deprecation path for a public API used by partners, so a change does not force them to rewrite overnight.

Event-Driven Integration

Perché: Lets you decide when an order flow should use events and queues instead of direct calls, and handle duplicates and ordering when the broker redelivers.

Zero Trust Architecture

Perché: Lets you design service-to-service access that verifies every call, so a compromised internal host cannot reach the rest of the network freely.

IAM Design

Perché: Lets you define roles and policies for a new system and block privilege escalation paths, before an over-broad permission becomes an audit finding.

Capacity Planning

Perché: Lets you estimate instances and database size for a launch from expected traffic, so the system does not fall over on the first campaign day.

Caching Strategies

Perché: Lets you pick cache layers and an invalidation rule for a read-heavy page, accepting a known staleness window instead of showing wrong prices.
