Beyond Traditional Bidding

Sotheby's, a name synonymous with prestige and luxury, approached us at Aranja with an ambitious vision. They aspired to create a high-end web auction platform that would enable global enthusiasts to bid on a diverse array of exquisite items, from high-performance sports cars to priceless works of art.

But Sotheby's wanted more than just a typical auction site. They envisioned a sophisticated and secure platform where bidding was not merely transactional. Their innovative concept incorporated a leaderboard system, aiming to transform the act of bidding into an engaging and interactive experience.

At Aranja, we revel in the enthusiasm of our clients and particularly value collaborations with those who bring clear and passionate visions. The Sotheby's project presented just such an opportunity, and we eagerly rose to the occasion.

Technology used

To bring this project to life, our team employed a cutting-edge tech stack, including Styled Components, TypeScript, Next.js, Nest, GraphQL, Urql, and TypeORM. With these innovative technologies, we developed a seamless, responsive, and highly functional platform that stands head and shoulders above industry standards.

Our mission was straightforward but intricate: to develop a world-class web auction platform reflecting Sotheby's brand's sophistication, with a focus on ensuring top-tier security for international buyers. The stakes were undoubtedly high. However, at Aranja, we're not daunted by significant challenges - in fact, we excel when faced with them. This platform was designed and developed by Aranja from 2022 to 2023. The project was architected and designed through many iterations to ensure it is as simple, user-friendly and secure as possible.
