Hi, I'm Mark
I'm a software engineer who investigates production issues, traces them to their root causes, and builds automation to make the next fix easier. I work across applications, integrations, and the Linux systems underneath them.
Selected work
From transaction rules to system administration, these projects show how I think through reliability, useful tooling, and clear interfaces.
I set up and maintain the Linux server that hosts this portfolio, including its web serving and access controls.
A private diary app for organizing daily notes and conversations, built with a React frontend and a Python API.
A Windows file sorting tool that turns a repetitive manual workflow into a predictable process.
A Spring Boot banking API for accounts and transactions, built to explore the rules behind moving money.
A Python API that gives multiple applications a shared interface for routed AI responses.
Experience
My production experience spans air and land cargo logistics and telecommunications. I enjoy following an issue across service boundaries, understanding the cause, and making the fix repeatable.
Accenture Inc.
Build and support backend services for logistics and telecommunications clients. Investigate production incidents, work through root cause analysis, and automate recurring support tasks.
Pawncare Services Inc. · Cebuana Lhuillier
Handled branch financial transactions under compliance requirements and built a spreadsheet tool to reduce repetitive interest and pawn value calculations.
Expertise
Detailed investigation, steady support, and small improvements that add up.
Trace failures through services and integrations, communicate what happened, and focus on the cause behind the incident.
Work across application behavior and the systems around it: web serving, access, certificates, logs, and deployment support.
Turn repeated manual steps into reliable tools and workflows, with validation and useful error reporting.

A little more about me
I'm Mark, a software engineer who likes understanding the details behind a system. That curiosity is why I enjoy production support: it asks me to learn quickly, connect evidence, and work with whatever the problem needs.
Outside work, you'll usually find me with an acoustic guitar, on a motorcycle, making coffee, or gaming.
I enjoy automation because it turns hard-won knowledge from one incident into a smoother experience for everyone who comes after.
