SITUATIONS WE KNOW WELL
"

"Our CRM doesn't talk to our billing system. Someone manually exports data from one and imports it into the other. It works until it doesn't — and nobody knows when it doesn't."

"

"We acquired a company with a different stack. Now we have two of everything — two customer databases, two order systems, two ways of reporting the same thing."

"

"We're building a product that needs to integrate with third-party APIs, and we're not sure how to handle rate limits, failures, and data consistency across services that don't coordinate with each other."

"

"Every new integration is a custom project. What we're calling integration is really point-to-point duct tape that only the person who built it understands."

HOW WE WORK

Four phases. No shortcuts.

Four phases. No phase is skipped. Each one produces something you can use, not just something that enables the next phase.

Phase 01 / 04
01

Discovery & Mapping

Phase 01 of 04
What happens

We map the systems that need to connect, the data that needs to move between them, and the failure modes that currently require manual intervention. We identify what's fragile, what's redundant, and what's missing.

What you do

Give us access to the systems and the people who understand the current workarounds — the manual steps everyone knows not to talk about.

What you leave with

An integration map showing every connection point, data flow, and known failure mode — before any code is written.

02

Architecture & Design

Phase 02 of 04
What happens

We design the integration architecture — API contracts, data transformation logic, error handling, retry strategies, and monitoring. We decide where consistency is critical and where eventual consistency is acceptable.

What you do

Review the design against your actual business workflows. Tell us which data mismatches would cause real problems and which ones are cosmetic.

What you leave with

A documented integration design with explicit trade-offs about consistency, latency, and failure handling.

03

Build & Integration

Phase 03 of 04
What happens

We build the integration layer — API wrappers, data pipelines, transformation logic, and error handling. Every integration point is tested against real data and real failure scenarios, not happy-path examples.

What you do

Provide test accounts, sample data, and access to the systems we're integrating with. Review integration test results in rounds.

What you leave with

Working integration code deployed alongside monitoring so you can see when data flows break before it causes downstream problems.

04

Handover & Monitoring

Phase 04 of 04
What happens

We hand over integration documentation, runbooks, and monitoring dashboards. Your team knows what to check, what to do when a connection fails, and how to add new integrations using the patterns we established.

What you do

Take ownership of monitoring and runbooks. Practice the failure scenarios during handover.

What you leave with

A monitored, documented integration layer your team can extend without rebuilding from scratch each time.

WHAT YOU GET

Deliverables are only useful if you know what they change.

Each output needs a commercial consequence. These rows show what the work changes, not just what gets handed over.

Integration system map

Your team sees every connection, data flow, and failure point — no undocumented duct tape.

Integration architecture design

Decisions about consistency, error handling, and retry logic are made deliberately, not discovered during an incident.

Working integration code

Data flows reliably between your systems. Failures are caught and handled, not silently corrupted.

Monitoring dashboards & alerts

You find out an integration is failing before someone in another department sends a frustrated message.

Runbooks & integration patterns

Your team can add new integrations without reinventing the approach each time.

COMMON QUESTIONS

Common questions

Access to the systems you want to integrate and someone who understands the current data flow — including the manual steps that exist because the integration hasn't been built yet. You don't need documented APIs for every system; we work with whatever access is available.

Heavily involved during discovery — your team knows the quirks of each system better than we ever will. During build, lighter involvement is fine; we need access to systems for testing and your review of integration test results.

You do. All integration code, API wrappers, documentation, and monitoring configurations are fully transferred at handover.

START A CONVERSATION

Tell us what you're building and where you're stuck.

We respond with a perspective, not a proposal. If there's a fit, we'll suggest a short call. If there isn't, we'll say that too.
