• Boosted operational efficiency by 60% by automating financial pipelines and cloud refresh cycles using KNIME and Python.
• Streamlined Power BI performance using DAX Studio and Power BI Helper to audit metadata and remove redundancies, significantly reducing memory footprint and file size.
• Engineered high-performance Oracle SQL extractions and refactored complex queries to ensure data integrity for enterprise-scale datasets.
• Enhanced report responsiveness for 5M+ records by utilizing Performance Analyzer to identify bottlenecks and refactor inefficient DAX expressions.

• Developed high-efficiency Python automation scripts, reducing manual data processing effort by 30%.
• Enhanced division-wide performance tracking mechanisms, bridging the gap between raw financial data and actionable business outcomes.
• Strengthened internal data governance by monitoring complex information flows across multiple international entities.

Used Technologies: SpringBoot, Maven, MySQL, Hibernate, IoC, Dependency Injection, Git/GitLab, JUnit, Postman, ReactJS, React Router, Material-UI

• Developed the database in MySQL and generated tables using Hibernate for better time management of the project
• Created REST APIs and tested in Postman and also created Mockito Unit Tests which tested the communication with the database and indicated the errors in the code
• Crafted the front end using ReactJS, which allowed the creation of reusable components, making it efficient to build and maintain the user interface.
• Integrated the communication between front-end and backend using URIs.

Used Technologies: IntelliJ IDEA, Maven, Spring MVC, Tiles, Hibernate, MySQL, MariaDB, IoC, Dependency Injection, Git/GitHub.

• Developed the backend in Java using Spring Framework, which gave the application modularity and scalability for further extension
• Created and connected the application to the database MariaDB using Hibernate, which allowed support customers with their uncertainties on various topics
• Implemented the project's front end using HTML5, CSS3, JavaScript for the core functionality and used Bootstrapv5 to enhance the overall design
