Rishit Ratna

As as SDE 1, I was responsible for designing and implementing both the high-level and low-level architecture of a service aimed at surfacing catalog defects to crowd-sourcing platforms. Additionally, I led the successful migration of an existing service from a single-tenant to a multi-tenant architecture using AWS. I coded the crucial business logic in Java and provisioned infrastructure through AWS CDK, guaranteeing seamless integration with the codebase. Simultaneously, I mentored a team of two interns for six months on a critical Data ETL (Extract, Transform, Load) pipeline project, which involved leveraging big data platforms like Hive, AWS Glue, and Spark to extract crucial metrics from clickstream seller data.

As an SDE2 at Amazon, my overarching role was to design and lead projects from inception to delivery. I spearheaded the creation of a Metadata Query Engine, transforming how business teams discover shared solutions. I developed a specialized domain-specific language (DSL) for frontend users to effortlessly create complex queries. I architected the AWS backend with Elastic Search for robust search capabilities and implemented a high-performance Java-based micro-service handling 50,000 TPS, ensuring low-latency data availability within 5 minutes. Additionally, I designed a self-service visualization tool for business teams, onboarded new engineers, reviewed and created technical documents, conducted code reviews, and maintained code quality through unit tests, integration tests, and load tests.
