Most production bugs come from messy integrations — flaky retries, hidden auth tokens in code, race conditions, and webhook handlers that swallow errors. We integrate the right way: idempotent, observable, and resilient when the third party has an outage.
We've wired up bKash, Nagad, SSLCommerz, Stripe, PayPal, Shopify, Tally, Sage, SAP, Zoho, HubSpot, Salesforce, Twilio, AWS S3, Google Maps, OpenAI, and dozens of custom partner APIs.
What we handle
- OAuth 2.0, JWT, HMAC, and API key authentication done correctly
- Webhook receivers with signature verification and replay protection
- Queued background jobs for slow third-party calls (no blocking the user)
- Rate-limit handling, exponential backoff, and graceful degradation
- Structured logging so you can debug 6 months later without re-reading the code
Typical engagement: 1–4 weeks per integration. Fixed-price quotes after a 30-min scoping call.
