API Engineering & System Integration

Connect Your Systems, Automate Data Flow, and Scale Without Bottlenecks

Modern digital businesses rely on interconnected ecosystems. Whether you need to integrate payment processors, sync inventory across third-party marketplaces, or connect your mobile app to legacy enterprise databases, our API engineering services make systems communicate seamlessly.

We build secure, developer-friendly APIs documented with OpenAPI/Swagger standards, fortified with token authentication, rate limiting, and real-time webhook event distribution.

System Integration Capabilities

• Payment Gateway Integration: Automated checkout, subscription billing, refund handling, and instant payment notification (IPN) webhooks.
• Communication & SMS Gateways: WhatsApp Business API, Twilio, transactional SMS, and automated email trigger pipelines.
• Third-Party CRM & Logistics Sync: Automated order dispatch to courier APIs (Pathao, Steadfast, RedX, DHL) and CRM data sync.
• Microservices & Event-Driven Architecture: Decoupled services communicating over Redis Pub/Sub, RabbitMQ, and Apache Kafka.

API Engineering Roadmap

1. API Specification & Schema Design: Defining OpenAPI / Swagger specifications and data contracts first.
2. Authentication & Security Layer: Implementing OAuth2, JWT tokens, IP whitelisting, and strict CORS policies.
3. High-Speed Endpoint Implementation: Building clean controller/service layers with Redis caching and eager loading.
4. Mock Server & Integration Testing: Validating edge cases, network timeout handling, and payload validation.
5. Deployment & Real-Time Telemetry: Production release with Datadog/Sentry error monitoring and detailed API usage metrics.
