Contract audit
We inventory producers, consumers, schemas, and retry semantics across services. Output is a prioritized backlog with risk notes for each sync edge.
Sync Horizon Integration Consulting
When event streams, APIs, and legacy databases disagree, your product teams wait on reconciliation scripts instead of shipping features. We take project-based engagements to design and implement integration layers that keep distributed systems aligned.

Problems we are called in to untangle
Duplicate order records appear when a checkout service and warehouse API both accept writes without a shared idempotency key. Nightly batch jobs mask drift until finance closes the month and totals diverge.
Teams add a message bus, then discover consumers apply partial updates in different orders. Without explicit synchronization contracts, “eventually consistent” becomes “never reconciled.”
We map these failure modes to concrete integration patterns—outbox tables, version vectors, compensating transactions—scoped to a fixed project statement of work rather than open-ended staff augmentation.
Your architecture diagram is not wrong; the handoffs between boxes are where production data silently forks. We instrument those edges first.
Implementation, not slideware
Engagements include reading your existing OpenAPI specs, Debezium connectors, or bespoke TCP feeds—whatever actually moves data today. We write the adapter code, migration playbooks, and observability hooks your SRE team can run.
Deliverables are tied to milestones: discovery memo, interface contract pack, staged rollout with rollback paths, and a handover session recorded for your internal wiki.
Project modules you can combine
Sync lane build
Design and code the integration path—Kafka topics, gRPC streams, or REST gateways—with idempotent handlers and dead-letter handling your team owns after handoff.
Cutover rehearsal
Shadow traffic, compare checksums, and run failover drills before you redirect production writes. Includes runbooks for on-call engineers.
Questions teams ask before signing
Do you embed full-time in our sprint room?
No. We work in project phases with defined artifacts. Collaboration happens through agreed channels and scheduled reviews, not indefinite seat rental.
Which stacks have you integrated?
Recent work spans JVM microservices talking to Node gateways, .NET monoliths feeding Python analytics lakes, and on-prem ERP sockets bridged to cloud object stores—always documented in the statement of work.
How is pricing structured?
Fixed-fee milestones quoted after discovery. We publish ranges on the services page; final fees depend on interface count and environment access.
