I'm a technical professional who maintains a strong work ethic with clients regardless of setting, whether within or outside Upwork. I set clear expectations on what I can achieve in a given timeframe, and I work best in an organized environment, especially under pressure.
I've built a varied 15+ year career in IT. I spent over a decade managing IT operations for one of the most well-known online travel agencies in the US — overseeing network operations including email, VOIP, and servers, and leading the Systems team. Alongside that, I spent several years as a remote IT technician for a US-based Managed Services Provider, supporting multiple client environments across Windows Server administration, workstations, and networking under SLA commitments — solid, proven experience delivering remote IT support directly to Western clients.
I'm also a Dell Certified System Expert with 5+ years of Level 2/SME technical support for a well-known computer manufacturer, and I have a strong graphic design background (13+ years, starting with Adobe Photoshop) alongside web design using Dreamweaver, HTML, CSS, and some PHP/Java. I have hands-on WordPress experience as well — I've managed and maintained WordPress websites for clients, and I currently run and manage my own WordPress site, so I'm comfortable with everything from content updates and plugin management to day-to-day site upkeep.
More recently, I've moved into e-commerce — handling Shopify, GA4, and marketing analytics for a growing online brand, including attribution tracking, UTM cleanup, and performance reporting.
Whether you need day-to-day IT support, a network/systems administrator, WordPress site management, or someone to bring order to your e-commerce data and operations, I bring reliability, attention to detail, and the flexibility to jump into whatever the job needs.
