Experts in API Integration and Integration Architecture for complex business systems.
When business systems must exchange data reliably, simple API connections are rarely enough. We design and build production-grade API integrations connecting ERP, CRM, e-commerce platforms, and internal systems - focusing on reliability, observability, and long-term maintainability.
Our work centers on custom integrations that support real business operations, not fragile scripts or quick automation hacks.

Design and implementation of reliable API integrations between ERP, CRM, e-commerce, marketing, and internal systems using REST APIs, webhooks, and secure authentication.

Design of robust integration architectures including data synchronization strategies, retry logic, monitoring, error handling, and long-term maintainability.
๐น On-premise Integration Platforms
Custom API integration hubs deployed on your infrastructure (Laravel / PHP), including scheduling, logging, monitoring, and full operational control.

I build the automation systems that run behind your business โ from Google Workspace tools to AI agents and n8n workflows โ replacing manual data entry, broken spreadsheet processes, and repetitive admin work with systems that hold up under real usage.
I built my track record automating Google Sheets and Workspace for growing teams โ CRMs, dashboards, and reporting systems that replaced paid software entirely. I'm now extending that same engineering approach into AI agents and n8n orchestration, wiring OpenAI-driven logic directly into the workflows I already know how to build reliably. I hold Google's AI Professional Certificate and I'm actively taking on projects in this space.
