Working full stack with Go, Java (Spring Framework) and Typescript/Javascript (React, Node.js) • Designed and wrote backend APIs (Java Spring, Go) for debugging and redelivering job applications• Implemented frontend UIs (React + Jest unit testing) and backend APIs (Node.js) to automate sending of emails and scheduling of interviews• Designed the backend system for reporting performance metrics (e.g. candidate response rate, time-to-response etc.). Considered multiple approaches with different trade-offs between consistency, data liveness and performance. Evaluated column-based analytics databases (e.g. Apache Druid) and chose DynamoDB. Reached consensus with multiple engineers who had conflicting opinions.• Integrated a machine learning model into our candidate search backend. Required configuring Kubernetes manifests and setting up gRPC.• Wrote team documentation that is opened by teammates multiple times a week. Mentored interns and planned their projects.
