Integrations and syncs
I connect the tools you already pay for, so nobody re-types data.
I build two-way syncs between your shop or job software, project board, PMS, Stripe and QuickBooks. Anything that doesn't map cleanly goes to a person to approve.
Best for: teams that re-type the same record between their job software, project board, PMS, Stripe or QuickBooks.
One flow from $3,500 fixed. Two-way syncs from $6,500 fixed.
Built for NorthMark Sign: over $4,000 a week saved · Top Rated on Upwork · 5.0 from 30 ratings
The same record lives in three tools.
A job, a booking or a payment gets typed into one system and then again into the next. Each copy is slow, and the systems drift apart.
How it's priced
One flow in one direction is a 5-Day Ops Agent Sprint at $3,500 fixed. Two-way syncs, and up to three connected flows for one industry, are an Industry System at $6,500 fixed, live in 7 to 10 business days.

What clients say on Upwork
We worked with Diego on a custom API integration between our ERP and project management platform, and he was outstanding from start to finish.
He handled both minor troubleshooting and complex system challenges with the same level of focus and care, keeping the project moving forward even when unexpected issues arose. His communication is clear, proactive, and transparent — he consistently explained his approach and made sure we understood each step.
Diego is responsive, technically sharp, and deeply reliable. If you’re looking for someone who can manage complex integrations while maintaining steady, professional communication, I highly recommend him.
Diego was incredibly efficient and consistently responsive throughout the entire project. His turnaround time and attention to detail saved me a significant amount of time and rework. While his hourly rate may appear high at first glance, the value is exceptional because he works quickly and gets it right the first time. I would absolutely work with him again and highly recommend him for any integration or development work.
Diego was outstanding to work with. He quickly understood the scope of our custom API integration, asked smart questions, and delivered exactly what we needed on time and within budget. His technical expertise, clear communication, and proactive problem-solving made the process smooth and stress free. I would absolutely recommend Diego to anyone looking for a reliable, highly skilled developer. A true 10/10 experience.
