ORGANIZATIONAL PROJECTS

REFSOLVE

Built a role-based medical web application using React.js, Express.js, and MySQL with features such as advanced search, user and admin access control, and structured hierarchical data grouping. The application was deployed on Google Cloud Platform (GCP) Compute Engine using Docker, ensuring a secure and scalable setup with basic data protection controls implemented, including restricted copy-paste functionality.

TROVE

Developed a responsive web application using React.js for managing medical-related data. Implemented two key search features to improve data accessibility and user experience. The first feature allows users to upload Excel files, which are parsed and used to filter matching records from a MySQL database through Express.js APIs, and the results are displayed in a dynamic table. The second feature enables keyword-based search, where user input is processed and matched against database records, with results fetched via APIs and shown in a structured tabular format.

PROFESSIONAL ACHIEVEMENTS

Recognized as Best Performer of the Month (October 2025) for significant contributions to project deliverables and consistent performance. Improved cost efficiency on Google Cloud Platform (GCP) Compute Engine by optimizing resource usage, leading to reduced monthly infrastructure expenses and better overall system efficiency. CAPSTONE PROJECTS

Designed and deployed a three-tier architecture on AWS using a custom VPC with multiple subnets across different availability zones. Set up networking components like Internet Gateway, NAT Gateway, route tables, and security groups with basic security practices. Deployed a Flask backend on private EC2 instances with Amazon RDS MySQL in isolated subnets, and hosted a frontend on a public EC2 instance using Apache. Used Application Load Balancers for routing and health checks between frontend and backend.
