Problems This Solves
Your product needs to communicate with external APIs (Stripe, HubSpot, Twilio, Salesforce), but your team lacks the backend engineering capacity to build reliable, compliant bridges.
Fragile third-party connections breaking silently during traffic spikes, dropping critical customer transactions and leaving sales and finance teams blind.
Security vulnerabilities caused by unauthenticated webhook endpoints, exposing your internal database to spoofed payloads and replay attacks.
Unpredictable third-party API rate limits (HTTP 429) causing integration jobs to fail mid-batch and corrupting historical customer records.
Our Proven Process
API Schema Mapping & Contract Design
We audit endpoints, request/response payloads, authentication models (OAuth2, API keys, JWT), and rate-limit constraints to design a resilient architecture.
HMAC Security & Replay Protection
Implementing cryptographic HMAC-SHA256 signature verification, timingSafeEqual comparisons, and 300-second timestamp drift windows.
Idempotency & Deduplication Engineering
Building an idempotent event processing layer that caches execution states and prevents duplicate operations when external services retry webhooks.
Rate Limit Throttling & Queue Management
Implementing token-bucket rate limiters and Celery/Redis queues that respect third-party quotas without dropping incoming events.
Fault Injection, Observability & Cutover
Stress-testing edge cases: network timeouts, malformed JSON, and upstream 5xx errors with automated dead-letter queue (DLQ) alerts and 30-day warranty.
