Full-Stack SaaS Engineering for a B2B Dropshipping Platform
TopDawg experienced 50% drop in support tickets and 99.9%+ uptime with new-age web app for retail logistics operations with AWS cloud hosting and full-stack development.
When Darren DeFao, CEO of TopDawg, appointed Radixweb, they needed to address the operational constraints of its dropshipping platform. The engagement covered end-to-end web app engineering, development of user-facing tools, integration with marketplaces, automation of core processes, and AWS cloud hosting.
Feedback Highlights
“They’ve consistently met our deadlines for major feature releases and integrations, even when timelines were tight.”
“Radixweb has consistently been receptive to feedback and quick to adapt when needed. Given the results and the quality of the partnership, I wouldn’t have done anything differently.”
We’ve worked with other development firms in the past, but Radixweb’s ability to integrate seamlessly with our internal team, adapt to shifting business priorities, and consistently deliver high-quality code across a complex tech stack is unmatched.
The Challenge and The Solution
Based in Florida, TopDawg is one of the leading U.S.-based B2B dropshipping platforms. Their existing platform was functional but a bit outdated by performance issues, limited automation, and fragmented integrations across multiple sales channels.
DevOptiv addressed these issues through full-stack redevelopment, AWS-based infrastructure provisioning, and the implementation of retailer dashboards, product catalog management, real-time inventory sync, order automation, and third-party integrations. The end result was a stable web application built for high-load performance under expanding transaction volumes.
They think strategically, ask the right questions, and proactively offer solutions that improve performance, scalability, and long-term maintainability.

An Overview of the Conversation
Please describe your company and your position.
TopDawg is a B2B SaaS platform that connects retailers with U.S.-based wholesale suppliers through a fully integrated dropshipping solution. We serve over 20,000 active retailers and host products from more than 3,000 suppliers. I am the CEO.
What was the primary purpose of bringing Radixweb into the project?
We hired Radixweb to build, manage, and continually develop our end-to-end B2B dropshipping platform. The scope included front-end and user interface design, development of back-end architecture, integration with multiple third-party services, and deployment of cloud hosting services on AWS.
How did you find Radixweb, and why did you select them over other firms?
We found Radixweb through an online search when we were reviewing potential vendors with experience in projects similar to ours. The decision to stick with them was based on three factors – their alignment with our organizational values, their work culture that operated compatible with ours, and the cost structure that seemed reasonable without risks.
Please describe the scope of work in detail, including key deliverables.
We've had about six to ten people working with us. Radixweb has served as our core development partner responsible for building and maintaining the TopDawg platform, which includes a custom-built web-based application for B2B dropshipping. They developed our full tech stack, from scalable cloud infrastructure on AWS to user-facing tools like our retailer dashboards, product catalog management, real-time inventory sync, order automation, shipping integrations, and API documentation. They've also played a major role in integrations with platforms like Shopify, Walmart Marketplace, and eBay. The team continues to deliver new features, resolve technical challenges, and provide DevOps support.
Could you share some measurable outcomes that indicate the project’s success?
Radixweb has been instrumental in helping us scale TopDawg into one of the leading U.S.-based B2B dropshipping platforms. We now serve over 20,000 active retailers and host products from more than 3,000 suppliers. Their development work enabled us to launch seamless integrations with Shopify, Walmart, and eBay, resulting in a significant increase in retailer adoption and product engagement. With their implementation of our infrastructure and automation capabilities, we've also seen a 50%+ reduction in support ticket resolution for order processing and platform errors. Our system uptime has remained above 99.9%, and platform response times have dramatically improved, providing a better overall user experience. These measurable improvements have helped us enhance retailer satisfaction, increase retention, and support consistent monthly revenue growth.
Their dedication, flexibility, and long-term commitment make them feel like an extension of our company rather than an outsourced team.
Final Remarks
What Radixweb did takes grit, patience, and a team that doesn’t lose focus. There were plenty of moments where things could have gone sideways, but the team did not lose the momentum. They’ve handled new feature development, urgent fixes, and complex integrations without letting stability slip. I’ve learned I can count on them, because every time, the results have been solid. That’s why they’re still at the heart of our platform’s growth.
A Measured
Collaboration
TopDawg entrusted us with the complete engineering and maintenance of their B2B dropshipping platform. In return, we have delivered technical depth, feature innovation, and integration strength. That steady, dependable way of working has kept the platform strong and the relationship productive, and it sets a solid foundation for everything still to come.
