• Decompose monolithic services into scalable microservices and design robust data pipelines across the platform
• Develop and maintain web and mobile applications using TypeScript, React/React Native, Python, and Node.js
• Work extensively with AWS services (application-level usage: S3, Kinesis, EC2, Fargate, IoT) to support enterprise-scale operations
• Own features end-to-end, from customer feedback through design, implementation, and production deployment
• Operate as a self-directed individual contributor in a fast-moving, low-bureaucracy environment
