Explore project
Context
An enterprise platform supporting corporate tax compliance across multiple processing and reporting workflows.
My Contribution
Designed and enhanced these workflows and completed approximately 5,000 tickets across product development and maintenance.
Technical Approach
REST and EJB services, JPA/EclipseLink facades, sharded SQL Server data access, database-backed MessageQueue records, JMS listeners/processors, and monitoring timers.
Monthly Summary Reporting
Created a React/TypeScript SPA with configurable AG Grid columns, search, comments and sign-off, balances, entity groups, source validation, Excel upload/export, and reprocessing.
- React
- TypeScript
- AG Grid
- Redux Toolkit
- React Router

Explore project
Context
A React/TypeScript single-page application supports monthly summary reporting workflows.
My Contribution
Created configurable data grids, search, comments and sign-off, balances, entity groups, source validation, Excel upload/export, and reprocessing.
Technical Approach
Used AG Grid for configurable columns, Redux Toolkit for state management, React Router for navigation, typed DTOs, and Axios service classes.
Payment AfterCare Tool
Built a standalone Spring Boot CLI comparing ATTM EIB Excel files with Workday payment text files by entity and filing period. It generates missing-file and field-comparison reports.
- Spring Boot
- Apache POI
- Spring JDBC
- SQL Server
- Oracle
- Maven

Context
The standalone CLI compares ATTM EIB Excel files with Workday payment text files by entity and filing period.
My Contribution
Built the tool to generate missing-file and field-comparison reports, with optional database lookups.
Technical Approach
Used Apache POI to read Excel files, properties-based configuration, and Spring JDBC for optional SQL Server or Oracle database lookups.
QA Verification Tooling
Developed Spring Boot tooling for QA, end-to-end, performance, and processor verification, using Excel inputs, JDBC data access, comparators, and existing tax-engine libraries.
- Spring Boot
- JDBC
- Gradle
- Apache POI
Explore project
Context
Spring Boot tooling supports QA, end-to-end, performance, and processor verification.
My Contribution
Developed REST controllers and verification workflows using Excel inputs, form and field exclusions, and existing tax-engine libraries.
