Creating Dashboard for Medical Project

#### Project Overview

The Medical Trial Dashboard is an advanced web application designed to monitor and display the progress of medical trials on patients. The application provides healthcare professionals with real-time data on the effects of various medicines under trial, enabling them to make informed decisions and track patient outcomes effectively.



#### My Role and Contributions

As a developer on this project, I played a crucial role in backend development and system optimization, utilizing my expertise in Node.js, Express.js, API creation, and resolving complex SonarQube issues. My contributions included:



1. **Backend Development:**

- **Node.js & Express.js:** I designed and implemented robust backend services using Node.js and Express.js. This involved setting up RESTful APIs to handle data retrieval, submission, and updating of trial information.

- **API Creation:** Developed secure and efficient APIs that facilitated communication between the frontend and the backend. Ensured the APIs were well-documented and met the requirements of various stakeholders.



2. **Data Management:**

- Implemented database schemas and integrated with MongoDB for storing trial data, patient information, and tracking logs.

- Utilized Mongoose for seamless data modeling and interactions between the application and the database.



3. **Error Resolution:**

- **SonarQube Integration:** Integrated SonarQube for continuous code quality checks and static code analysis.

- **Resolving Complex Errors:** Addressed and resolved complex SonarQube issues, including code smells, bugs, and vulnerabilities. This ensured our codebase maintained high standards of quality and security.



4. **Performance Optimization:**

- Conducted performance tuning and optimization of API endpoints to handle large volumes of data efficiently.

- Implemented caching mechanisms and optimized database queries to enhance the responsiveness of the dashboard.



5. **Collaboration and Documentation:**

- Worked closely with frontend developers, designers, and healthcare professionals to ensure the application met user requirements and provided an intuitive user experience.

- Created comprehensive documentation for the APIs and backend services, facilitating easier onboarding and maintenance for future developers.



6. **Security Enhancements:**

- Ensured the application followed best security practices, including proper authentication, authorization, and data validation.

- Regularly updated dependencies and patched vulnerabilities to protect against potential threats.



#### Technologies and Tools Used

- **Node.js** for server-side programming.

- **Express.js** for building the backend framework.

- **MongoDB** with **Mongoose** for database management.

- **SonarQube** for static code analysis and maintaining code quality.

- **JWT** (JSON Web Tokens) for secure user authentication.

- **Postman** for API testing and documentation.



#### Impact and Outcome

The Medical Trial Dashboard significantly improved the efficiency and accuracy of monitoring medical trials. Healthcare professionals could quickly access and analyze trial data, leading to better patient outcomes and streamlined decision-making processes. The application’s backend was highly praised for its reliability, performance, and security, largely due to the thorough development and quality assurance processes I implemented.



This project exemplified my ability to deliver high-quality, scalable, and secure backend solutions, showcasing my skills in Node.js, Express.js, API development, and resolving complex code issues.
