A Career Built on Understanding Systems — and People

I entered the hosting world in 2009, after several years working hands-on with hardware in a local computer shop and in laptop repair at Jabil Circuit. I enjoyed fixing things properly, but I wanted to work on larger systems — infrastructure that supported real businesses at scale.

Learning Infrastructure the Hard Way (2009–2012)

I started at Hostway on July 1, 2009, during a period when infrastructure was still very physical and deeply hands-on. As a NOC technician, I was responsible for building, imaging, and racking servers—primarily Dell PowerEdge hardware—along with supporting Cisco ASAs, Fortinet and BSD firewalls, and Linux-based iptables shared firewalls. Within six months I was promoted to L2 Support, taking on customer-facing tickets and support calls while continuing to work regularly in the data center. Hostway emphasized root-cause resolution and long-term stability, and that mindset shaped how I still approach systems today: understand how things fail, then design them so they don't fail again.

Exposure to Scale and Cloud (2012–2014)

At HostGator, I was exposed to hosting at massive scale—supporting high-volume environments with millions of domains. At Datapipe, where I worked as a Unix System Administrator, I gained early exposure to hybrid cloud architectures and AWS-adjacent infrastructure. Together, these experiences clarified what I enjoyed most: environments where deep technical understanding, customer trust, and thoughtful design all mattered.

Returning as a Technical Account Manager (2015–2023)

In January 2015, I returned to Hostway—later Ntirety—as a Technical Account Manager. This role brought everything together. As a TAM, I served as the bridge between clients and engineering teams, helping organizations operate, scale, and modernize complex infrastructure. I worked closely with large customers, including Wix, and traveled internationally to support client relationships, including multiple trips to Israel and visits to teams and customers across the U.S. and Europe. I became known for handling complex environments and high-stakes situations calmly and thoroughly. By early 2023, after many years of continuous on-call work, I was ready for a reset.

A Deliberate Reset and Reinvestment (2023–Present)

In February 2023, I stepped away from full-time employment and intentionally took time to recalibrate—something I hadn't done since I was a teenager. This period has been active and purposeful, not idle. I focused on personal resilience and performance, improved my physical health through cycling, and invested heavily in community involvement and leadership. Professionally, I returned to technology on my own terms—building cloud-native applications, exploring AI tools, and re-engaging with the security community.

Where I'm Headed

I'm now looking to return to a Remote Technical Account Manager role. I bring more than 15 years of perspective across legacy infrastructure, cloud transitions, and client-facing technical leadership. I understand how systems used to be built, how they fail, and how modern, cloud-native architectures can be designed to avoid those failures altogether. Most importantly, I'm calm under pressure, clear with clients, and effective at translating complexity into confidence. That's the value I'm ready to bring to my next team.

What I've Been Up To

Community leadership, entrepreneurship, cycling, side hustles, and experimenting with AI tools every single day.

AI ToolsExperimentation

Experimentally Building with AI Tools Every Day

This is where I spend most of my technical time: pushing AI coding tools to their limits. ChatGPT, Gemini, Claude, Cursor, Antigravity, Claude Code, MCP Servers. Running local models on Nvidia Jetson Nano with ollama, programmatic LLM data enrichment via Google AI Studio. Learning what these tools can actually do—and where they break. This website, FareScout, and countless experiments are all built this way.
