What I'm looking for

I am looking for a role that allows me to leverage my IT expertise in a collaborative environment, focusing on innovative solutions and continuous improvement.

As a Senior Systems Administrator, I have a proven ability to optimize IT infrastructure, reduce costs, and strengthen security. My hands-on experience in cybersecurity, incident response, and disaster recovery planning ensures compliance with industry standards. I take full ownership of technology strategy, aligning systems with business needs while maintaining performance, security, and reliability.

In my current role at Pasternak & Fidis, P.C., I manage IT operations in a law firm environment, supporting attorneys and staff with secure technology solutions. I have successfully reduced annual IT costs by 15% and automated system patching, improving reliability. My commitment to security is evident through my implementation of monitoring tools and structured training programs for employees.

Previously, I worked as an IT Engineer at Econometrica, where I led the deployment of computer systems and optimized Azure cloud environments. My technical expertise has allowed me to develop standard operating procedures that enhance IT workflows and ensure business continuity. I am passionate about leveraging technology to drive efficiency and support organizational goals.
