What I'm looking for

I seek a technical role where I can apply system administration, networking, and data science skills in a collaborative, growth-oriented company focusing on operational excellence and measurable impact.

I am an IT professional with a strong foundation in Mathematics and Computer Science, focused on system administration, network management, and data-driven problem solving. I bring hands-on experience across telecommunications, enterprise IT, and data science.

As Head of Business Operations at an Application Service Provider, I led day-to-day operations, optimized network performance, and drove process improvements to enhance service delivery. I have managed vendor relationships and contributed to strategic growth initiatives.

In technical roles I administered Linux and Windows Server environments, implemented virtualization with VMware and Hyper-V, and used tools like Wireshark and SolarWinds to maintain network health. I am proficient in Python (Pandas, NumPy, Matplotlib, Seaborn), Matlab, and SQL for data analysis and visualization.

I also tutor data science and research methods, and deliver motivational talks focused on academic excellence and leadership. I am passionate about applying coding and IT skills to solve complex problems in forward-thinking organizations.
