01
Domain-driven design
Event storming and dependency mapping to find the bounded contexts that can genuinely stand alone.
Principal / Lead
Hire principal architects for monolith-to-microservices migrations
Architects who break a monolith apart one bounded context at a time — routing traffic gradually, verifying parity in shadow mode, and avoiding the big-bang rewrite.
Role profile
What we look for in a Principal Microservices Migration Architect
Seniority and experience are agreed in the proposal, and you interview every engineer before they start. These are the skills that interview should test.
02
Strangler-fig routing
A routing layer in front of the monolith, shadow traffic to compare responses, and cutover one route at a time.
03
Sagas and consistency
Sagas with compensating actions in place of distributed transactions, coordinated with Temporal or Kafka.

FAQ
Questions about hiring a Principal Microservices Migration Architect
Answered the way we would on a call. If yours isn’t here, send it — we reply within one business day.
No big-bang rewrite. One bounded context at a time moves behind a routing layer, runs in shadow mode until its responses match, and keeps a rollback path until it has proven itself in production.
With sagas: each step commits locally and publishes an event, and a failure triggers compensating actions for the steps already done. Temporal or Kafka coordinates the steps.
Not always. If the real problems are slow deploys or a tangled codebase, a modular monolith may solve them for far less. We'll tell you if that's the better route before any services are split out.
