Architecture · integration · modernization

Software architecture and system integration for business-critical platforms.

I help teams turn complex requirements into maintainable architectures, reliable APIs, clear data ownership and phased modernization plans.

Domain and workflow decomposition

REST APIs, PostgreSQL and integration boundaries

Idempotency, retries, audit and observability patterns

Incremental modernization instead of risky all-at-once rewrites

Architecture should make failure understandable.

A good architecture is not the one with the most services. It is the one where responsibilities are clear, data ownership is explicit, integrations can be retried safely and production failures can be diagnosed.

Architecture work can include

System and domain decomposition
API contracts and integration strategy
Database and event-flow design
Authentication, authorization and audit boundaries
Deployment, observability and failure-recovery planning
Legacy assessment and phased replacement roadmaps

Trade-offs are documented, not hidden.

For every major choice—monolith versus services, synchronous versus asynchronous processing, cloud versus on-premise, relational versus document storage—the decision should be tied to actual scale, team capability, operational risk and change frequency.

Start with the operating problem

Have a system that is becoming difficult to change or trust?

I can review the architecture, integration boundaries and operational failure modes and turn them into a prioritized modernization plan.
