API Development & System Integration
Design, build, and operate the APIs and integrations that let your enterprise applications talk to each other — reliably and securely.
Connect Every System You Run
Modern enterprises run on integration. Pro Lens designs and delivers REST, GraphQL, and event-driven APIs, plus middleware and EAI that connect ERPs, CRMs, portals, and legacy systems into one coherent platform.
From API strategy and gateway design to legacy adapters and real-time event pipelines, we build integrations that are secure, observable, and built to last.
Plan Your Integration
API & Integration Capabilities
REST & GraphQL API Design
Well-designed, documented, and versioned REST and GraphQL APIs — aligned with OpenAPI standards and built for developer experience.
System Integration Architecture
Enterprise integration patterns, architecture blueprints, and reference implementations that map cleanly to your application landscape.
Middleware & ESB
Middleware and enterprise service bus implementations using modern platforms — routing, transformation, and orchestration across systems.
Legacy System Integration
Adapters, wrappers, and facades that bring mainframe and legacy applications into a modern API-driven architecture without a full rewrite.
API Gateway & Management
API gateway setup, rate limiting, authentication, developer portals, and full API lifecycle management for governance and control.
Event-Driven Integration
Kafka, message queues, and event-streaming pipelines that enable real-time, decoupled communication between enterprise systems.
Why Choose Us for API & Integration
API-First Approach
We design APIs as products — contracts first, with clear versioning, documentation, and developer experience at the core.
Vendor-Neutral Architecture
We pick the right integration stack for your landscape — not the one that maximises a vendor's license revenue.
Security & Governance Built-In
OAuth2, mTLS, quotas, audit logs, and gateway policies applied by default — not bolted on later.
Monitoring-Ready Delivery
Every integration ships with logging, metrics, and tracing hooks so operations can see what's happening from day one.
