API & System Integration
Make your stack talk to itself.
Connect the tools that should already be connected: CRMs, payment systems, ERPs, marketing platforms, internal databases. Reliable, observable, recoverable — not duct tape.
API Integration Services
Production integrations to the SaaS tools your business runs on.
Connect Salesforce, HubSpot, NetSuite, Slack, Zendesk, and the long tail of internal APIs. Built with rate-limit handling, retries, idempotency, and replay on failure.
Custom API Development
REST or GraphQL APIs designed for the long haul.
API design with versioning, pagination, rate limiting, auth, and OpenAPI specs — so your partners and frontend can rely on it.
CRM Integration
Salesforce / HubSpot / Pipedrive ↔ your stack.
Bidirectional CRM sync with conflict resolution, custom field mapping, and operator tools to inspect and replay events.
Stripe Integration
Stripe done right — billing, Connect, Tax, the full surface.
Payments, subscriptions, marketplaces (Connect), and tax handling — all with the webhook discipline that prevents the "why didn't the customer's account update?" tickets.
Payment Integration
Stripe, Adyen, Square, KOMOJU, or local rails for Japan.
Multi-provider payment integrations including Japanese rails (konbini, bank transfer, PayPay), with unified abstraction so your product code doesn't care who's processing.
Salesforce Integration
Salesforce that talks to everything else cleanly.
Custom objects, Apex when needed, Bulk API, Streaming API — and the operational tooling to keep it healthy. We don't paper over Salesforce; we make it work for you.
HubSpot Integration
HubSpot beyond the standard integrations.
Custom HubSpot integrations including private apps, custom objects, workflows triggered from external events, and bidirectional sync with your application data.
Google Workspace Integration
Gmail, Drive, Calendar, Sheets — wired into your product.
Google Workspace integrations: OAuth flow, Gmail send/receive, Calendar booking, Drive folder management, Sheets as a lightweight data source — with proper consent and scope management.
Webhook Automation
Reliable webhook delivery, both ways.
Outbound webhook systems with retries and signing, and inbound webhook receivers with idempotency and replay. The boring infrastructure that makes integrations not break at 3am.
Data Sync Systems
Two-way sync with conflict resolution, not a one-way ETL.
Sync engines connecting two or more systems with conflict resolution, change-tracking, and operator tools for inspection and replay.
