Middleware Development
Create custom middleware for secure and standardised communication between different enterprise systems.
Build Custom MiddlewareOverview
Modern enterprises rely on multiple systems—CRMs, ERPs, accounting tools, and legacy platforms. GullySystem builds robust middleware to unify these systems with secure, scalable, and real-time data exchange. We streamline workflows, reduce redundancy, and enable true interoperability.
Benefits
Seamless System Communication
Connect your software stack using middleware that standardizes data flow between independent applications or services, ensuring smooth and efficient operations.
Faster Integrations
Reduce development time for new systems by using middleware as a common communication layer across platforms, accelerating your integration projects.
Data Consistency Across Apps
Ensure reliable data exchange and consistency between front-end apps, back-office tools, and third-party systems, maintaining data integrity throughout your ecosystem.
Security & Access Control
Middleware acts as a secure layer to handle API authentication, encryption, rate limiting, and request validation, protecting your systems from unauthorized access.
Legacy System Bridging
Extend the life of legacy software by bridging it with modern tools without needing to rewrite existing systems, maximizing your past investments.
Event-Driven Architecture Support
Enable real-time updates and trigger-based actions by integrating middleware with message queues or event streams, supporting dynamic and responsive applications.
What’s Included
System Discovery & Data Flow Mapping
Identify all source and destination systems; map required endpoints and define secure integration routes for a clear understanding of your data landscape.
Custom Middleware Layer
Build platform-agnostic middleware using Node.js, Laravel, Python, or Java to effectively route, transform, and manage data between your applications.
Authentication & Security Logic
Implement API keys, JWT, OAuth2, or custom token-based access to protect data in transit between systems, ensuring robust security for your integrations.
Data Transformation & Normalization
Convert data formats (CSV, XML, JSON) and structure fields to ensure seamless compatibility between systems, eliminating data inconsistencies.
Asynchronous & Real-Time Support
Design synchronous API-based flows or use message brokers like RabbitMQ, Kafka, or Redis Pub/Sub for real-time delivery, adapting to your data exchange needs.
Error Handling & Monitoring
Log, retry, or alert on failed transactions using custom error handling rules and integrated monitoring tools, ensuring the reliability of your data flows.
Tools & Technologies We Use
Programming Languages
Node.js, Laravel (PHP), Python (FastAPI), Java Spring Boot for building robust and efficient middleware services.
Message Brokers & Queues
Kafka, RabbitMQ, Redis Streams, MQTT for asynchronous and scalable communication, ensuring reliable data flow.
Security & Auth
JWT, OAuth2, API keys, mTLS, HMAC, and IP allowlisting for secure data exchange and access control.
Integration Tools
Postman, Swagger, REST, SOAP, GraphQL APIs, webhooks for seamless system interaction and connectivity.
Monitoring & Logs
ELK Stack, Prometheus, Grafana, Sentry for comprehensive performance and error tracking, ensuring system health and stability.
