- Isolated PostgreSQL database metrics and generated queries to provide snapshots of database health, performance, and optimization.- Enforced static type error handling by defining Typescript interfaces and custom types which guaranteed scalability, reduced inadvertent type coercion and runtime errors, and improved understandability across the codebase. - Developed a Node.js server using Express for dynamic routing and real-time data updates. Implemented custom middleware to efficiently deliver database metrics in response to user dashboard interactions.- Utilized a centralized state management tool Zustand, simplifying state logic and fostering code reusability.- Implemented Docker to package application with its dependencies into portable containers to ensure persistent development and performance across environments.- Implemented a comprehensive regression testing suite with Jest and React Testing Library leading to a 40% improvement in code reliability and streamlining the detection of UI inconsistencies before deployment.- Applied Chart.js library to generate customizable charts with built-in features, enhancing the user experience.- Utilized Tailwind CSS and Radix UI to develop responsive, modular React components, enhancing the visualization of database metrics and boosting UI development speed.- Facilitated scrum methodologies to optimize productivity and project delivery timelines with a team of 5 engineers via Jira.- Produced under tech accelerator OSLabs (opensourcelabs.io).
