What I'm looking for

I am seeking hands-on engineering roles focused on maintenance, reliability, and infrastructure support where I can apply troubleshooting, root-cause analysis, and asset management to improve system performance.

I am a Mechanical Engineering graduate with hands-on experience in engineering operations, maintenance, and infrastructure support across academic and industry settings. I have monitored end-to-end network performance, conducted root cause analysis on power-related outages, managed assets, and used ServiceNow for incident management to uphold SLA-based resolution.

I have designed and fabricated laboratory systems and small-scale biogas and water purification projects, performed mechanical and electrical diagnostics in automotive settings, and supported community outreach and sustainability initiatives. I am detail-oriented, adaptable, and committed to promoting safe, efficient, and sustainable engineering operations.
