Vijay Saini

Over the course of my tenure at Coinbase, I've been instrumental in driving impactful projects that have significantly contributed to the company's success.

Policy Rule Engine: At Coinbase, I am proud to serve as a core member of the only Tier 0 service in India. As the owner of this pivotal service, I oversee its operations as a platform for other services within the organization to evaluate their rules effectively. This engine plays a critical role in answering queries such as "Can user X perform action Y in the context of Z?" This high-throughput service boasts exceptional scalability, accommodating up to 10 million requests per minute.

Decentralized Identity (DiD): As the founding engineer of the Decentralized Identity (DiD) Project, I contributed into creation of a cutting-edge platform that revolutionizes digital identity ownership. Our innovative solution empowers individuals to possess and control their identities on-chain, ensuring heightened security and privacy. One of the key features of this project is the provision of subdomains to users utilizing ENS domains, facilitating seamless and intuitive management of decentralized identities.

At Angel One, I developed Smart Store Service, a dynamic marketplace tailored for treading-related products. As the lead engineer, I crafted this platform to empower sellers to list their offerings and enable buyers to seamlessly purchase trading products
