Connect Any System — Even Without a Good API
Custom integrations for REST APIs, GraphQL, webhooks, legacy tools, and platforms that were never designed to talk to each other.
TL;DR
Not every system has a clean, well-documented API. Some have outdated documentation, some use proprietary protocols, and some have no API at all. I specialize in connecting these difficult systems using custom middleware, reverse-engineered endpoints, browser automation, and direct database connections. If data lives in a system, I can get it out and push it where it needs to go.
When Your Systems Won't Cooperate
Your business runs on a mix of tools built in different decades by different vendors. Your accounting software talks to nothing. Your field service platform has a REST API that was last updated in 2019 and is missing half the endpoints you need. Your inventory system only exports data as nightly CSV dumps. Your industry-specific ERP was built before APIs were standard.
Zapier, Make, and the rest only work with clean, well-documented APIs. When your system is not in their catalog, you're on your own. So your team compensates — exporting files, re-keying data, building spreadsheet bridges that break whenever a column changes. The real cost isn't just the hours lost. It's that your team makes decisions based on data that's incomplete, stale, or flat-out wrong.
Custom Connections for Every System
I build integrations that go beyond what pre-built connectors can do. If a system has a REST or GraphQL API, I use it — handling authentication, pagination, rate limits, and error recovery properly. If the API is incomplete or undocumented, I reverse-engineer the endpoints that your web interface uses internally. If there is no API at all, I can connect through direct database queries, file-based transfers, or headless browser automation.
Every integration I build has error handling, retry logic, data validation, and logging baked in. When an API changes or a connection drops, the workflow doesn't silently die — it retries on its own and pings you if it genuinely needs a human. The end result is a reliable data pipeline between systems that were never designed to work together.
How We Connect Your Systems
API Assessment
I analyze each system you need to connect — what APIs exist, what authentication methods they support, what data is accessible, and where the gaps are. This assessment determines the best integration approach for each system.
Connection Architecture
I design the integration architecture — which systems push data, which pull, how conflicts are resolved, and what happens when a connection fails. You get a clear diagram of data flow before any building starts.
Build Custom Connectors
I build the necessary connectors, middleware, or automation nodes in n8n. For difficult systems, this may involve custom Node.js modules, browser automation scripts, or database adapters.
End-to-End Testing
Every integration is tested with real data across the complete data path — from source to destination and back. I simulate failures, rate limits, and edge cases to verify the system recovers gracefully.
