Integrations that hold up in production.

From API interfaces to legacy connectivity: cleanly designed, tested close to production, fully documented and handed over. No interface engineering that breaks on first live run.

API Design & Interfaces

Interfaces that not only function but remain stable under load, during failures and after releases. We design API-first — with versioning, monitoring and operational maintainability in mind.

  • — REST and SOAP — contract-first, with versioning and backwards compatibility
  • — Endur- and Triple A-specific integration points, proprietary formats and protocols
  • — Error handling, retry logic, timeout strategies and idempotency guarantees
  • — API monitoring: latency, error rates, SLA tracking and alerting

Messaging & Event Streams

Publish/subscribe, event streaming, queue-based processing — for trades, positions, market data and settlement events. We assess and integrate; we do not dictate messaging stacks.

  • — Apache Kafka, IBM MQ, ActiveMQ/Artemis, AMQP — depending on existing infrastructure
  • — Pub/sub patterns for trading events: trade capture, position updates, risk feeds
  • — Dead-letter queues, replay mechanisms, ordering guarantees and error handling
  • — End-to-end monitoring for message flows: throughput, latency, error rates

Batch/File Pipelines & ETL/ELT

File-based data flows remain central to most ETRM environments. We build and stabilise batch pipelines for settlement, risk values, market data and reporting — with error handling, reconciliation and operational monitoring.

  • — CSV, FpML, XML and proprietary ETRM formats — parsing, validation, mapping
  • — ETL/ELT pipelines for settlement, position data, risk metrics and market data
  • — Scheduler integration, dependency management, job monitoring and alerting
  • — Reconciliation logic and error escalation with clear operational processes

Legacy Connectivity & Modernisation

Mature ETRM landscapes contain legacy components that cannot simply be replaced. We work pragmatically: adapters and anti-corruption layers where rip-and-replace makes no sense — and clear modernisation paths where it does.

  • — Adapter patterns and anti-corruption layers for legacy ETRM interfaces
  • — Incremental modernisation without operational risk: strangler fig, branch by abstraction
  • — Assessment: what to modernise, what to wrap, what to replace — with clear priorities
  • — Cloud connectors for Azure, AWS: landing zones, security baselines, hybrid setups

Target Architecture & Operational Handover

Architecture Review

Analysis of the existing integration landscape: weaknesses, risks, redundancies — with concrete actions and priorities.

Target Architecture Design

From current state to target architecture: realistic, incrementally deliverable, with operational costs and scaling in mind.

Operational Handover

Runbooks, data flow documentation, monitoring setup and knowledge-transfer sessions — for independent operation without dependency.

Frequently Asked Questions

Which messaging systems do you work with?
Kafka, IBM MQ, ActiveMQ/Artemis, AMQP-based systems — depending on existing infrastructure. We assess and integrate; we do not impose stacks.
Can you work with proprietary ETRM interfaces?
Yes — including Endur-specific integration points, Triple A data feeds and other platform-specific formats and protocols.
What do you mean by "production-ready"?
Error handling, retry logic, idempotency, monitoring and alerting are part of the design — not additions made after something breaks in production.
Do you review existing integration landscapes?
Yes — with clear findings, risk assessment and prioritised actions. No action catalogue without implementability.
How do you hand over integrations to internal teams?
With operational documentation, runbooks, monitoring configuration and knowledge-transfer sessions — so the team can operate independently.
How do you approach legacy systems?
Pragmatically. No rip-and-replace without justification. Adapters, anti-corruption layers and incremental modernisation where feasible and sensible.
