Building Connections That Actually Work
We're the team that makes different systems talk to each other seamlessly. Since 2021, we've been solving integration challenges that keep businesses running smoothly. No buzzwords, no false promises – just solid technical expertise applied to real business problems.
How We Got Started
The Problem We Kept Seeing
Back in early 2021, I was consulting for a mid-sized logistics company. Their inventory system couldn't communicate with their new shipping platform. Sales data lived in one place, customer service tools in another. Sound familiar?
That's when it hit me – most businesses struggle with the same fundamental issue. They have great individual tools, but those tools don't work together. The technical solutions exist, but finding someone who understands both the technology and the business impact? That's much harder.
So we started Marquex to bridge that gap. Not as another generic tech consultancy, but as specialists who focus exclusively on making systems work together better.
What We Actually Do
Three core areas where we help businesses eliminate friction and improve workflow efficiency
API Integration
We connect your existing software so data flows automatically between systems. Whether it's CRM to accounting software or inventory to e-commerce platforms, we make it happen without disrupting daily operations.
External Service Setup
Payment processors, shipping APIs, communication tools – we handle the technical setup and testing so these services work reliably from day one. Less time troubleshooting, more time focusing on your customers.
System Architecture
We design integration frameworks that grow with your business. When you add new tools or scale operations, your systems remain stable and connected without major overhauls.
Meet Our Lead Architect
Vincent Kellerman
Vincent has been solving integration problems since 2018, working with companies from 20-employee startups to 500+ person organizations. He started in database administration, then moved into API development when he realized most business inefficiencies stem from poor system communication.
What sets Vincent apart is his ability to explain complex technical concepts in plain English. He spends significant time understanding how each business actually operates before suggesting technical solutions.
"The best integration is one that business users never have to think about," Vincent often says. "It just works, quietly, in the background, making everyone's job easier."
When he's not architecting integrations, Vincent mentors junior developers and contributes to open-source API documentation projects. He believes good documentation saves everyone time and reduces project complexity.
Our Approach to Integration Work
Test Everything Thoroughly
We run extensive testing scenarios before any integration goes live. This includes edge cases, high-volume periods, and failure recovery. Better to catch issues in our test environment than in your production systems.
Document the Details
Every integration comes with clear documentation your team can reference later. We include troubleshooting guides and explain how to monitor system health. Knowledge shouldn't be locked in one person's head.
Plan for Growth
We design integrations that handle increased data volume and new feature additions. What works for 100 transactions per day should also work for 1,000. Scalability gets built in from the start, not added later as an afterthought.
Keep Communication Clear
Technical projects can get confusing quickly. We provide regular updates in plain language about progress, challenges, and next steps. You'll always know where things stand without needing to decode technical jargon.
