Antonette Petallo_

IT Support Analyst & Technical Problem-Solver
patient, resourceful, and obsessed with clarity.

I help people feel confident with their technology
whether that means fixing issues, simplifying processes, or creating better workflows.

Support Develop Innovate

Behind the Screens

precision + empathy

My journey in IT started from a simple curiosity: why things break and how to make them work better for people. Since then, I’ve built a foundation that mixes technical support, customer experience, and problem-solving across academic, enterprise, and small business environments.

I’ve supported users at McMaster University’s UTS Service Desk, contributed clearer documentation, resolved daily Windows/macOS issues, and even built internal tools to make workflows easier. What motivates me is simple... helping someone move from stressed to relieved with a fix that actually makes sense.

How I Work

support that feels calm, clear, and human

🧭 Support philosophy

  • Clarity first. I take time to understand the real problem before giving any steps. Clear guidance beats rushed fixes.
  • Stay calm, even when users aren’t. Tech issues can be stressful — my job is to make the experience feel manageable and respectful.
  • Think before escalating. I walk through common fixes, validated steps, and past KB entries before moving a case up.

🗂️ Beyond “just closing tickets”

  • Better documentation. I rewrite confusing fixes into cleaner KB articles so the next analyst doesn’t start from zero.
  • Workflow awareness. I look for patterns — what keeps breaking, what slows users down, and what processes can be simplified.
  • Follow-through matters. “Resolved” isn’t real until the user confirms everything is working again.
