Sadda Qayyum

Hi, I’m Sadda 👋 I’m a freelance software engineer specialising in custom Sharetribe marketplace development. I work with founders and teams who are building on Sharetribe and need help extending it beyond out-of-the-box features—without overcomplicating the product. That includes Sharetribe configuration, API-driven custom development, and integrating third-party services like Stripe Connect, messaging tools, and external systems. I’ve been building web applications for over 10 years, with the last 5+ years focused almost entirely on marketplaces. I’ve implemented core marketplace functionality many times, including onboarding, listings, pricing and availability logic, search and filtering, booking and transaction flows, payouts, messaging, reviews, admin tools, and post-purchase experiences. Because of this, I’m very familiar with Sharetribe’s capabilities, limitations, and the edge cases that tend to show up as marketplaces grow. My approach is practical and product-driven. Before writing code, I focus on understanding the business goal behind each feature, defining clear requirements, and identifying technical and product trade-offs early. This helps avoid wasted effort, keeps development predictable, and ensures custom features are stable and maintainable. A few important things to know about how I work: I’m a hands-on developer I specialise in Sharetribe Flex customisations, custom React frontends, and API integrations I work closely with designers and founders to translate product ideas into buildable, scalable solutions I’m comfortable explaining technical decisions in plain language If you’re looking for a developer who understands Sharetribe deeply, thinks like a marketplace founder, and can help you build the right custom features at the right time, I’d be happy to chat.
