API design & gateways
REST, GraphQL and gRPC APIs designed for longevity — versioned, documented, rate-limited, and protected by an API gateway. The contract between your systems, written once, evolved carefully.
We design and build custom system integrations that connect ERPs, CRMs, e-commerce platforms, accounting suites, warehouses, and legacy databases into one coherent operational layer. REST and GraphQL APIs, event-driven architectures, ETL and CDC pipelines, real-time bidirectional sync — engineered by senior integration architects, not configured by a wizard.
Mid-market companies typically run 10 to 20 disconnected tools — an ERP that doesn't know about the e-commerce site, a CRM that doesn't see fulfilment, a warehouse system rekeying orders by hand. The tax shows up as duplicate data, late invoices, missed inventory, and three people whose job is really just copy-paste. We build the integration layer that absorbs that work — not as a brittle Zapier chain, but as a documented, monitored, vendor-neutral system you own.
REST, GraphQL and gRPC APIs designed for longevity — versioned, documented, rate-limited, and protected by an API gateway. The contract between your systems, written once, evolved carefully.
Batch, incremental and change-data-capture (CDC) pipelines that move data between operational systems and the data warehouse — schema-aware, idempotent, and rebuildable from source on demand.
Message brokers and event buses that decouple your systems: each tool publishes what it knows, each tool subscribes to what it needs. The foundation for real-time operations, observability, and graceful failure.
When the right answer is a managed integration platform — we deploy and operate iPaaS tools properly: error queues, retries, observability, version control. Configured by engineers, not by a marketing department.
SOAP, EDI, flat files, AS/400, on-prem SQL — the systems your business still depends on but vendors won't touch. We build the bridge that lets modern tools talk to them safely, without ripping out what works.
Two systems, one source of truth — handled correctly. Conflict resolution, idempotency keys, replay protection, audit trails. The kind of sync that survives a network partition without leaving your data corrupted.
Every operation can be replayed safely. Network failures, duplicate webhooks, and retries don't corrupt data — they're absorbed.
Dashboards, alerts, structured logs, lineage. When a flow breaks, you know within seconds — not when a customer phones in.
Every flow, schema, and contract is in version control with the code. The person who replaces us in three years can read it and continue.
Your integration layer doesn't depend on one provider. If a SaaS tool changes terms or shuts down, you replace the connector — not the platform.
RESULT —Most engagements ship the first production flow inside three weeks. Full integration coverage is typically reached between week eight and week sixteen.
Every integration engagement runs the same arc. We map what exists before we touch it, design before we build, build before we automate, and operate until the system can run without us.
We inventory every system, every flow, every workaround. The output is a written integration map — systems, data, ownership, frequency, current pain — that you keep regardless of whether we proceed.
Integration architecture, data contracts, sequencing, fallback behaviour. Decisions made on paper before they get expensive in code — including the ones that need to age well.
Senior hands only. Two-week cycles. First production flow inside three weeks. Every connector ships with tests, monitoring, runbooks, and documentation that survives staff change.
We monitor, evolve, and transfer ownership: connector upgrades, schema migrations, knowledge transfer to your team. Until the integration layer can grow without us — which is the point.
“Three people used to spend full days reconciling stock between channels. After the integration went live, the entire role disappeared — and no one was made redundant. They moved into work that was actually theirs.”
A non-exhaustive map of platforms, protocols, and patterns we work with day-to-day. If your system isn't listed, it almost certainly speaks one of these languages — and if not, we'll build the bridge.
Where the system of record lives — and where most integration projects either succeed or quietly fail.
The interface between your pipeline and the rest of the operation. Almost always sitting on its own island until someone connects it.
Storefronts and gateways that need real-time inventory, order, refund, and tax sync — without breaking checkout.
The plumbing layer: brokers, pipelines, warehouses, and the tools that move data between them safely.
The wire formats themselves — from modern APIs to the EDI and SOAP your supply chain still runs on.
The long tail — comms, scheduling, identity, storage. The integrations no one talks about that quietly hold an operation together.
Don't see your system? It's likely one we've worked with — ask.
Send us your stack →If you're scoping an integration project, these are the answers you actually need — written by the engineers who do the work.
System integration is the engineering practice of connecting independent software systems — ERPs, CRMs, e-commerce platforms, accounting suites, custom applications — so they exchange data and trigger actions automatically, in a way that's reliable, observable, and auditable. It matters because every duplicate spreadsheet, rekeyed order, and reconciliation meeting is a tax on growth. Properly integrated systems remove the rekeying, surface the right numbers in real time, and let the team focus on work software can't do.
Zapier, Make and n8n are excellent for simple, low-volume flows — and we deploy them when they're the right answer. They become a liability when business logic gets complex, volumes scale, or auditability matters: error handling is shallow, version control is informal, and the integration logic lives in someone's account. Custom integration means engineered, version-controlled, monitored code — typically a hybrid: managed platforms for the simple flows, custom services for the critical ones. We choose per flow, not as a religion.
Single-system integrations (one connector, well-defined scope) usually ship in three to six weeks. Multi-system operations layers — ERP, CRM, e-commerce, warehouse, accounting — typically take eight to sixteen weeks to reach full coverage, with the first production flow live in week three. The longest part is rarely the code; it's mapping how the business actually works versus how the org chart says it does.
Yes, and roughly a third of our work touches a legacy system the original vendor no longer actively supports. We build an anti-corruption layer between the legacy system and the modern stack: the legacy keeps doing what it does well, and the rest of the operation talks to it through a clean, documented interface. No risky big-bang migration — just a bridge that lets you replace the legacy later, on your timeline.
You do. Every line of code, every connector, every runbook, every dashboard. The integration layer lives in your repositories, runs on your infrastructure (or one we deploy and hand over), and is documented well enough that another engineering team — yours or someone else's — can pick it up. We don't hold the keys, and we don't gate-keep what we built.
Yes. Giroteam is based in Málaga, Andalusia, but most engagements are remote across the EU, the UK and increasingly the US East Coast. We work in English, Spanish and German, on European business hours by default, with overlap into other time zones arranged per engagement.
“We'd had two failed integration attempts before Giroteam — both with bigger names. The difference wasn't the technology; it was that the senior who scoped the work was the same person handing over the code five months later. There was nothing lost in translation, because there was no one to translate to.”
