Full Stack Developer at AQR Capital Management

March 1, 2024 - Present

At AQR Capital Management, I worked on developing the Portfolio Risk Management System, collaborating with quant analysts, PMs, and compliance teams in agile sprints. I developed a React frontend with dynamic dashboards and interactive charts using D3.js, optimized PostgreSQL databases with advanced indexing on AWS RDS, and built Spring Boot microservices for complex risk calculations with asynchronous processing improving computation speed and scalability. I created comprehensive automated tests integrated in Jenkins CI/CD pipelines on AWS CodePipeline, reducing deployment errors and streamlining release cycles. I also worked with DevOps to deploy and monitor the application on AWS ECS using Docker containers with autoscaling and CloudWatch monitoring, ensuring 99.9% uptime and secured environment variables.
