About this gig
Tired of integrations breaking, duplicating data, or becoming hard to manage?
Most systems work at first, but fail as complexity grows - unclear logic, no structure, constant fixes.
What I do
I design API integration architecture and system workflows before anything is built.
Clear data flow, defined mapping, and predictable structure - not fixes after things break.
What you'll get
- Defined integration use cases
- Clear data flow (what triggers what)
- Field mapping (source destination)
- Basic validation rules
- Error handling approach
- Clean, predictable structure
How this works
Each package covers a defined number of integration use cases.
A use case is one specific action between systems (e.g. create OR update OR delete).
More complex integrations are split into multiple use cases or handled in phases.
Before ordering
Describe your systems and use case so I can confirm the scope.
If your case is larger, I'll suggest the right structure or the next phase.
If you need reliable integrations, not fragile setups, let's talk.

I’m Max, Integration Architect and founder of QPMSoft.
Most integrations fail not because of APIs, but because of missing architecture. I focus on building systems that are reliable, traceable, and built to last.
I design and implement API integrations across ERP, eCommerce, CRM, and finance — from scratch or by replacing fragile Zapier/Make workflows. Every system includes logging, retries, and full data visibility.
If you need a stable integration, not a quick fix — let’s talk.

FAQ
Why should you choose me?
I focus on designing integrations that work reliably before they are built. Clear structure, defined data flow, and decisions that prevent issues later.
What’s included?
Each package covers a defined number of integration use cases. A use case is one specific action between systems (create OR update OR delete).
What’s NOT included?
Full system architecture, multi-step processes, or large integrations across many use cases. If needed, I’ll suggest the right structure or next phase.
What is a use case?
A use case is one specific action between systems, such as create, update, or delete. Each use case covers one action only.
Can one use case include multiple actions?
No. Create, update, and delete are separate use cases. Each action is handled individually.
Can you design both directions (sync both ways)?
No. Each direction is a separate use case. Example: A → B and B → A are two use cases.
What if my integration is complex?
Complex integrations are split into multiple use cases. If needed, I’ll suggest the right structure or next phase.
What systems can you design for?
Any systems that support APIs or data exchange. If unsure, describe your case and I’ll confirm.
Do you build the integration as well?
Yes, but separately. This gig is for design. Implementation is handled in my API Integration or Automation gigs, depending on your setup.
What do you need from me to get started?
A clear description of your systems and what each use case should do. Example: When an order is created, send it to another system.

I hired Max to perform an integration job between two systems. He did a fantastic job and completed very quickly and was very customer responsive. The work was complex and told me the good and the bad and options needed to achieve good result. Very happy with his work and I would highly recommend him...
