Craft-led stream architecture

CoreStream Consulting

We design and harden event stream processing pipelines for teams that need Kafka, Flink, or Pulsar to behave predictably under production load—not just in a slide deck.

Engagements are scoped projects and advisory sessions from our Hualien office, with remote working sessions across Taiwan.

Scoped delivery

How we take stream work from sketch to running code

Discovery advisory

Single or multi-session reviews of topic design, serialization choices, and consumer lag risks before you commit engineering weeks.

Implementation project

Fixed-scope builds: stream joins, stateful operators, schema registry wiring, and observability hooks your SRE team can own.

Stabilization sprint

Short engagements to tame poison messages, rebalance partitions, and document runbooks when an existing cluster misbehaves.

Asymmetric focus

Capabilities we bring to stream-processing craft

Operator design

Windowing, watermarks, and side-output patterns chosen for your latency budget—not copied from a generic template.

Delivery hygiene

CI checks for schema compatibility, contract tests on event payloads, and replay strategies documented for on-call engineers.

Staggered delivery rhythm

A craft-minded path through complex streams

1 · Map the event contract

We inventory producers, keys, and retention needs, then draft topic boundaries that survive the next product pivot.

2 · Build with observability first

Metrics on lag, deserialization failures, and checkpoint health land before feature logic so you can trust nightly releases.

3 · Hand off operable artifacts

Runbooks, sample Flink or Kafka Streams jobs, and architecture notes written for the team maintaining the system—not for a vendor demo.

Questions teams ask before booking

One platform only?

We advise on Kafka-centric stacks most often, but also support Pulsar and managed offerings when they fit your compliance and ops model.

Remote sessions?

Workshops and pairing sessions run over secure video; on-site time in Hualien County is available when you need whiteboard-heavy design work.

Scope clarity

A written scope lists deliverables—code modules, diagrams, test harnesses, or review memos—plus session count and acceptance criteria agreed before work starts.
