API & integrations

API development & third-party integrations.

Connect products, CRMs, payment systems, and internal tools with integration work designed for the awkward parts: retries, rate limits, partial failure, and data that arrives twice.

Reliable integration is product work.

An integration is not finished when two systems can exchange a request. It is finished when the team knows what happens after a timeout, a duplicate webhook, a revoked token, a rate limit, or an event that arrives out of order.

Integration work I can own

REST APIsDesign and implement endpoints with clear inputs, outputs, validation, and error behavior.

OAuth and accessConnect third-party accounts with token handling, scopes, refresh behavior, and tenant context.

WebhooksReceive, verify, persist, process, and retry events without coupling the request to every downstream action.

Data synchronizationMap fields, ownership, lifecycle states, and conflict behavior between systems.

Event-driven workUse queues and background jobs when the workflow should not block the user-facing request.

Legacy connectionsWork around older interfaces while creating a cleaner boundary for the rest of the product.

A dependable integration path

Event→Verify→Persist→Queue→Process→Observe

Retries need idempotency. APIs need rate-limit behavior. Webhooks need a durable event record. These details are where integration confidence is won.

Why this matters to the product

Good integration work keeps the customer experience, CRM, billing state, and internal operations aligned enough that your team can act on the data with confidence. It also gives AI workflows and MCP tools a better foundation to use.

Questions buyers ask

Integrations that keep working after launch.

Can you integrate with our CRM or third-party SaaS tools?

Yes. The implementation depends on the available API, authentication method, events, field mapping, and the business rules around ownership and updates.

How do you handle webhook retries?

Persist the event, verify it, make processing idempotent, move longer work to a queue, and create a recovery path for events that continue to fail.

Can you work with a legacy API?

Often. The goal is to isolate the legacy behavior behind a boundary so the rest of the product does not inherit every constraint.

Do you build new APIs or only integrations?

Both. New APIs often provide the durable contract that makes integrations, internal tools, and AI tool interfaces easier to build and maintain.
