AI API Integration Architecture Validation Max did another fantastic job taking us through the validation phase of our Bizware project. Heā€™s fast, knowledgeable, easy to work with, and consistently delivers exactly what we need. Weā€™re closing out this phase and immediately hiring him again to move into MVP development. Highly recommend Max!

Recall.ai & Zoom API Integration Architecture Max did an excellent job reviewing the scope for our project. He was fast, thorough, and helped keep the project focused on the big picture while identifying important technical considerations. Communication was excellent throughout the process, and I really appreciated his expertise and efficiency. I'm already starting another project with Max and would absolutely recommend him to anyone looking for a skilled full-stack developer.

Kyiv, UkraineĀ - 4:19 am local time
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.

šŸ§© What We Do

šŸ”¹ API Integration & System Connectivity
Design and implementation of reliable API integrations between ERP, CRM, e-commerce, marketing, and internal systems using REST APIs, webhooks, and secure authentication.

šŸ”¹ Integration Architecture
Design of robust integration architectures including data synchronization strategies, retry logic, monitoring, error handling, and long-term maintainability.

šŸ”¹ On-premise Integration Platforms
Custom API integration hubs deployed on your infrastructure (Laravel / PHP), including scheduling, logging, monitoring, and full operational control.

šŸ”¹ API Development & Consulting
End-to-end API development: REST API design, OAuth authentication, webhook processing, multi-system integration strategies, system audits, and integration consulting.

šŸ”¹ Data Synchronization
Reliable data pipelines between ERP, CRM, analytics, and internal systems with validation, monitoring, and recovery mechanisms.

āš™ļø Our Strengths

āœ… Strong focus on API integration for complex business workflows (finance, e-commerce, logistics, marketing operations)
āœ… Production reliability by default - logging, retries, monitoring, and alerts included
āœ… Security-first architecture suitable for on-premise and private cloud deployments
āœ… End-to-end ownership - from architecture and API development to deployment and long-term support

šŸ§  Tech Stack

Languages & Frameworks: Laravel / PHP / Node.js / Python
Integration Technologies: REST APIs, Webhooks, OAuth, event-driven integrations
Platforms & APIs: HubSpot, QuickBooks Online, Xero, Shopify, Acumatica, BigCommerce, Airtable, Slack, Notion, Google Workspace
Infrastructure: AWS, DigitalOcean, Docker, Linux
