Custom API & Middleware Integrations background

Enterprise API Integration &
Custom Middleware
Engineering

Bridge the gap between legacy on-premise systems, proprietary databases, and modern cloud applications with secure, low-latency API wrappers and middleware services.

✓

Connect Legacy to Modern: Bring modern cloud capabilities to older internal systems without full rewrites.

✓

High-Throughput Data Transfer: Engineered for low-latency batch processing and real-time event streaming.

✓

Enterprise Security: Fully encrypted communication with mutual TLS and OAuth2 authentication.

Problem & Solution

Legacy Software Shouldn't Hold Your Business Back

Older ERPs, proprietary databases, and legacy platforms hold critical business data, but lack the modern REST/GraphQL APIs needed to connect with newer cloud tools.

The Problem

Pre-built Zapier/Make connectors do not support proprietary or on-premise databases, leaving your data trapped in silos.

The Problem illustration
The Solution

We build custom API wrappers, middleware microservices, and database connectors that expose your legacy data securely to your modern automation stack.

The Solution illustration

Core Capabilities

Legacy System API Modernization

Wrap older SQL databases, AS400, or desktop ERPs in secure REST/GraphQL endpoints that modern cloud tools can easily query.

Data Transformation Middleware

Microservices that normalize, clean, and validate data payloads on the fly between platforms with conflicting data structures.

Webhook Ingestion Engines

High-throughput listeners capable of receiving, queuing, and processing thousands of concurrent webhook events per second.

Custom Third-Party API Connectors

Build private integrations for specialized industry software that lacks pre-built connectors on popular platforms.
