Hi, I'm Donald Vu
Application Support Engineer | Technical Support Engineer | Data & Operations Analyst | Security+ Certified | SQL • Python • Troubleshooting • Automation
About Me
Security+ certified Data and Operations Analyst with 3+ years of experience troubleshooting systems, automating workflows, and improving team efficiency through data-driven solutions. I’m now focused on pursuing Technical and Application Support roles, where I can apply my analytical and communication skills to ensure reliable operations, resolve technical issues, and support users across environments.
I’ve built automation tools, dashboards, and SQL workflows that reduced manual workload and improved reporting accuracy. My background in system monitoring and log analysis (via Security+ and TryHackMe) gives me the technical awareness to identify root causes and maintain stable, secure systems.
When I'm not working, I enjoy playing basketball, following the NBA, focusing on health & wellness, playing video games (especially Valorant), watching anime, and enjoying psychological/thriller movies.
