About Me

Get to know me better

I'm a dedicated Computer Science student with a passion for solving complex problems through technology. My experience spans backend development, systems programming, machine learning, and distributed computing, from enterprise Java and Spring Boot data pipelines to filesystems and networking in C/C++. I enjoy working in collaborative environments and am always eager for challenges and to learn new technologies and methodologies.

Experience

Where I've worked

Backend Software Developer Intern
NISC (National Information Solutions Cooperative)
May 2026 - Aug 2026

Oracle-to-PostgreSQL Migration

Java
Spring Boot
Spring Batch
Hibernate
Apache PDFBox
  • Replaced a legacy Crystal Reports batch job with a Spring Boot / Spring Batch application, using Hibernate ScrollableResults to stream across five joined entities for memory-efficient processing on both Oracle and PostgreSQL.
  • Built a multi-section PDF reporting engine with Apache PDFBox (dynamic grouping, subtotals, grand-total aggregation, cross-category deduplication), slated for the company's annual year-end processing.
  • Verified cross-engine correctness with JUnit 5 and Testcontainers integration tests against isolated Oracle and PostgreSQL containers.

Credit-Transfer Provider Priority

Java
SQL
Bash
  • Refactored a legacy Java billing module by swapping integer-based dispatch for a polymorphic enum, extracting shared loops to remove redundant SQL, and eliminating mutable inter-method state, cutting code volume ~40% with verified behavioral parity to production.
  • Implemented configurable provider-priority ordering for credit-transfer targets, combining SQL-driven ranking with an extensible class hierarchy for override behavior.
  • Developed a Bash script to automate credit-transfer batch runs, integrated into the company's year-end processing pipeline.
