APIs and service contracts.
Design interfaces around real consumers and meaningful boundaries. Clarify authentication, data shapes, version changes, limits, and how errors are communicated.
When it helps
Make the moving parts visible.
An integration is more than a successful request. It needs a clear source of truth, safe access, predictable behavior when something fails, and someone who can see what happened.
- 01Manual handoffs are slowing the business.
- 02A product needs payments, identity, or external data.
- 03Disconnected systems need a dependable workflow.
What we take on
The work behind the progress.
Business systems and workflows.
Connect identity, payments, content, customer systems, and internal operations. Make the ownership of data and the sequence of actions explicit.
Cloud and operational foundations.
Plan environments, configuration, secrets, deployment, and visibility around the application’s needs. Keep cost, complexity, and responsibility part of the decision.
Automation with recovery.
Handle retries, duplicate events, partial failures, and reconciliation. Where intelligent features help, define their role, evaluate the output, and preserve an appropriate human decision point.
Decisions & detail
Depth where
it makes a difference.
Specific questions, deliberate tradeoffs, and useful artifacts that make the work understandable.
Contracts both sides can rely on.
Specify request and response shapes, authorization, pagination, error semantics, and version changes. For events and background jobs, define delivery expectations and duplicate handling. Use contract checks and realistic failure cases to test the connection.
The artifact: documented API contracts, sample requests, integration checks, and ownership for changes.
Commerce beyond the checkout button.
Map the full commercial journey: product information, pricing, availability, carts, checkout, payment status, orders, refunds, and fulfillment. Clarify where tax and shipping rules are configured and which platform owns each record. Account for subscriptions or entitlements when they belong to the product.
The decision: hosted commerce, a headless storefront, or a custom application connected to specialist services—based on the operating model.
Make money and order states agree.
Use payment-provider capabilities for sensitive payment handling and reconcile the application with provider events. Plan for delayed or repeated webhooks, abandoned checkouts, failed renewals, stock changes, and partial refunds. A successful browser redirect alone should not be the source of truth for payment.
The artifact: an order/payment state map with retry, reconciliation, and support paths.
Infrastructure with clear ownership.
Separate development, staging, and production needs. Define permissions, secrets, storage, background work, infrastructure configuration, and operational signals. Choose managed services where they reduce the burden without hiding costs or creating an unacceptable dependency.
The artifact: an environment map, service responsibilities, and an operational runbook.
What you take forward
Something you can work with.
The exact scope is agreed around your product. These are the kinds of outputs that turn the work into a useful next step.
- A map of systems, data flows, and ownership
- Documented API and integration contracts
- Implemented workflows with tested failure paths
- Operational signals and recovery instructions
The goal is a connection the business can depend on and the team can understand. Successful requests, interrupted work, and unusual conditions should all have an intentional path.
Access should match responsibility. Sensitive data should travel only where it needs to, credentials should stay outside application content, and external services should be treated as dependencies that can change or fail.
