Profile

Senior Technical Support Engineer with 12+ years of operational background in distributed systems.

Specialist in turning vague customer reports into reproducible engineering bugs at the T2/T3 escalation layer.

Deep experience with Linux CLI, API debugging (Postman), and log analysis.

Reliable US overnight / Follow-the-Sun coverage from Bangkok (UTC+7).

Core strengths

Operational Discipline.

Systematic debugging
I isolate variables across networks, APIs, and Linux environments to find the root cause.
Engineering empathy
I convert vague customer reports into structured bug tickets with clear reproduction steps, attached payloads, and isolated log traces.
Operational toil reduction
If I have to do a diagnostic check more than three times, I write a Bash or Python script to automate it.
Reliable handoffs
Ensuring critical overnight escalations are diagnosed, triaged, and resolved before the US morning shift begins.
Professional Experience

Support & Operations.

Ops-Diagnostics (Python & Bash)

Featured Repo
GitHub / h-vance

Streamlining production incident response through automated verification.

  • The Symptom: Manual verification of production application services was slowing down initial ticket triage and increasing Mean Time to Resolution (MTTR).
  • The Investigation: Support teams needed a faster way to confirm if a reported outage was a localized user issue or a broader service degradation.
  • The Resolution: Developed lightweight Python diagnostic scripts to automatically ping endpoints, parse health status, and monitor application log files for recurring error patterns.
  • Impact: Reduced manual verification time and accelerated engineering escalations.

Log-Rotation-Maintenance (Bash)

Featured Repo
GitHub / h-vance

Preventing service degradation through automated storage maintenance.

  • The Symptom: Unmanaged production application logs risked filling server storage, potentially leading to service degradation and lost diagnostic data.
  • The Resolution: Implemented automated Bash scripts for log rotation, compression, and cleanup on Linux servers.
  • Impact: Ensured continuous availability of storage.
  • Stability: Preserved critical logs for post-incident RCA.

Cloud-Operations-Runbook

Featured Work
GitHub / h-vance

Standardizing complex troubleshooting workflows for distributed systems.

  • The Impact: Authored and maintained 15+ comprehensive technical SOPs.
  • The Value: Standardized common support tasks and reduced tribal knowledge.
  • Efficiency: Improved the efficiency of the broader support team by providing repeatable troubleshooting paths.
  • Reliability: High-fidelity documentation for zero-to-one engineering teams.
