Integration services,
set with intention

Each engagement is priced, timed, and scoped like a printed commission — no hidden middleware, no perpetual license theatre. Select a line item to open an inquiry.

N° 01

Low-Latency Data Ingestion Endpoints

Production-grade ingestion gateways that absorb high-volume event streams without collapsing under burst traffic. Built for sub-50ms acceptance windows, backpressure awareness, and clean handoff into your internal queues.

  • HTTP / gRPC / Webhook intake
  • Idempotent replay buffers
  • Per-tenant rate envelopes

N° 02

Standardized Schema Transformers

Deterministic mapping layers that convert heterogeneous payloads into your canonical schema. Versioned transformations, field-level validation, and explicit rejection paths — so downstream systems never inherit surprise shapes.

  • Canonical model design
  • JSON / Avro / XML paths
  • Regression fixture suites

N° 03

Third-Party API Adapter Development

Thin, supervised adapters for payment processors, CRMs, ERPs, and marketing platforms. We absorb their quirks — pagination folklore, undocumented limits, surprise deprecations — so your core services stay calm.

  • OAuth2 & token lifecycle
  • Retry & circuit-breaker logic
  • Provider contract tests

N° 04

Legacy-to-Cloud System Bridge

Controlled coexistence for on-premise estates moving toward modern platforms. Dual-write windows, reconciliation ledgers, and progressive cutover plans that leave the old vault intact until the new sky is proven.

  • Cutover rehearsal drills
  • Dual-write reconciliation
  • Rollback-first architecture

N° 05

Real-Time Webhook Orchestrator

A deliberate dispatch spine for outbound events: ordered delivery, signed envelopes, dead-letter quarantine, and replay tooling your on-call engineers will actually thank you for.

  • HMAC-signed envelopes
  • Ordered fan-out queues
  • Dead-letter replay UI

$980

N° 06

Authentication Gateway Configuration

Unified identity at the edge of every integration: token exchange, service accounts, least-privilege scopes, and audit trails that satisfy both your security board and your platform team.

  • OAuth2 / OIDC wiring
  • Secrets rotation policy
  • Access audit exports

$750

N° 07

Rate-Limit & Throttling Layer

Protective pacing for shared upstream providers and your own public surfaces. Token buckets, sliding windows, and graceful degradation that keep integrations alive when a partner decides to surprise you.

  • Token-bucket algorithms
  • Per-consumer quotas
  • 429-aware retry maps

$650

N° 08

Pipeline Monitoring Dashboard

Quiet visibility into every integration hop: lag, error budgets, schema drift, and throughput curves rendered for humans. Alerts that respect your attention instead of exhausting it.

  • Lag & error budget views
  • Schema drift warnings
  • On-call friendly alerts

$1,100

N° 09

Multi-Cloud API Mesh Deployment

Cross-cloud integration meshes for teams that refuse single-provider lock-in. Service discovery, mutual TLS between meshes, and routing policies that keep traffic honest across regions.

  • AWS / GCP / Azure hops
  • Mesh service discovery
  • mTLS between boundaries

$3,200

N° 10

Schema Registry & Versioning System

A single source of truth for every contract your integrations share. Compatible evolution rules, consumer approval gates, and a registry that survives the next reorganisation.

  • Contract version policies
  • Consumer approval gates
  • Compatibility linting

N° 11

Integration Testing Harness

Contract tests, sandbox traffic replay, and chaos drills that catch integration rot before production does. A harness your CI pipeline will enforce without theatre.

Continuous Adapter Maintenance Retainer

A quiet monthly partnership for teams who already run on our bridges: dependency upgrades, partner deprecation watch, schema drift patches, and priority dispatch when a provider changes the rules overnight.

  • Deprecation watch
  • Priority patch window
  • Monthly health review
