About me

At University of North Florida, I focus on systems-level development, enterprise computing, and the intersection of reliability and modern software design. My experience spans C, Java, as well as leveraging IBM's z/OS with hands-on work using ISPF/TSO, JCL, Zowe CLI, and dataset management on mainframe environments. Beyond coursework, I explore AI-driven systems and low-level software architecture projects that demand precision, performance, and long-term maintainability. I'm particularly drawn to roles that bridge legacy and modern infrastructure where understanding both the technical depth of traditional systems and the agility of contemporary development makes a real impact.

Technical Focus

Interested in systems programming and mainframe computing, I enjoy working with low-level tools, utilizing platforms like z/OS, and exploring how large systems are designed and maintained.

IBM Mainframe Technologies (z/OS)
C, Java, Python, JCL, COBOL
Object-Oriented Software Design
Automation & CLI Tools
Database Management & Reliable Data Handling
Systems Thinking

I'm drawn to the intersection of classic enterprise reliability and modern development practices, aiming to build software that's both durable and elegant in design.

Projects & Experience

Selected projects that explore systems programming, enterprise computing, and software design. Each reflects a focus on reliability, clarity, and low-level implementation detail.

Why these?

I like working close to the metal, writing programs that interact directly with systems and infrastructure. My projects often revolve around understanding how complex environments like z/OS, compilers, and databases function, and how to design tools that make them more accessible and efficient.

Annuity Calculator (COBOL + JCL)

Interactive z/OS program using COBOL and JCL to compute future annuity values.

SIC Assembler (WIP)

Two-pass assembler implementing symbol tables and object code output for SIC instructions.

Library Management System (PostgreSQL + JDBC)

Java + PostgreSQL application using JDBC for CRUD operations and record tracking.

Road Traffic Analysis (OOP + ETL)

This project analyzes roadway volume and speed data for a single corridor using multiple sensors and produces summary metrics (totals/averages) and simple quality checks.
