I am a Principal Software Engineer at Microsoft, father, nerd, gamer, and speaker.

I’m thrilled to share that I’ve been promoted to Principal Software Engineer at Microsoft!

The Journey
#

It’s been an incredible four and a half years at Microsoft, and this milestone still feels a bit surreal. When I joined Microsoft in October 2021 as a Senior Customer Engineer on the Fast Track for Azure (FTA) team, I was living a dream I’d had since childhood. I never imagined the journey would bring me here.

During my time on the FTA team, I worked directly with customers adopting Azure, helping them architect and build cloud-native solutions. It was an amazing experience - every engagement brought new challenges, new architectures, and new opportunities to learn and teach.

In late 2024, I moved to the Azure Reliability (AzRel) Risk SRE team, a shift that pushed me into entirely new territory. As the lead for the Platform Reliability Pillar, I dove into outage analysis, building AI-driven tooling with OpenAI and Semantic Kernel to help engineers understand failures and strengthen Azure’s reliability at scale. It was a big change, but it reinforced something I’ve always believed - growth comes from stepping into the unfamiliar.

Looking Forward
#

As a Principal Software Engineer, I’m continuing to focus on Azure reliability - building tools and systems that help keep the platform running smoothly for millions of users worldwide. I’m also doubling down on the things I’m passionate about:

  • Building - AI-powered tooling for reliability engineering, distributed systems, and cloud-native applications
  • Speaking - sharing what I’ve learned at conferences around the world, from NDC and Techorama to DevSum and Aspire Conf
  • Community - organizing DevOps Days Tampa Bay, active with Tampa Devs and multiple local meetups, mentoring, and contributing to open source
  • Writing - more blog posts, more samples, more sharing

What Does Principal Mean at Microsoft
#

For those curious about what this level means at Microsoft, I wanted to share some context. At Microsoft, engineering levels form a career ladder, and the jump from Senior to Principal represents a meaningful shift in scope, impact, and expectations.

A Senior Software Engineer (levels 63-64) typically executes complex features, leads projects within a single team, designs components, reviews code, and mentors team members. The focus is largely on the how - delivering high-quality work within established frameworks.

A Principal Software Engineer (levels 65-67) operates differently. The role shifts toward strategic technical leadership - defining architecture across multiple teams, solving organization-wide problems, and aligning technology decisions with business goals. The focus moves to the why - long-term strategy, navigating high ambiguity, and innovating beyond existing solutions.

Some of the key differences:

  • Scope of Impact - Senior engineers own projects within a team. Principals influence entire organizations, divisions, or large-scale technical strategies
  • Technical Focus - Principals handle high ambiguity and innovate beyond existing solutions. Seniors work within established frameworks to deliver features
  • Leadership - Principals guide technical direction, manage stakeholders, and mentor other senior engineers. Seniors focus more on day-to-day implementation and mentoring junior staff

For me, this promotion reflects the way I’ve been working - constantly sharing knowledge, educating the team, and helping set technical direction. Whether it’s building alignment across orgs and teams, driving architecture decisions, or connecting people and ideas across organizational boundaries, the Principal role formalizes what I believe great engineering looks like at scale.

At its core, it comes down to a growth mindset. The willingness to step into ambiguity, learn continuously, and lift others up along the way. That’s what got me here, and it’s what I’ll keep doing.

Gratitude
#

None of this happens alone. I’m grateful for the incredible teammates and mentors I’ve had on both teams, the managers who championed my growth, and the community that keeps pushing me to learn and share. And of course, my family - who support all the late nights, conference travel, and the constant tinkering.

If you’re on your own career journey, here’s what I’d say: don’t be afraid to take the leap into unfamiliar territory. The skills you’ve built are more transferable than you think, and the best growth happens outside your comfort zone.

Here’s to the next chapter. Let’s build something great.

Two Incredible Years at Microsoft

Two Incredible Years at Microsoft: A Journey of Growth, Connection, and Remote Collaboration # As I sit at my desk, keyboard beneath my fingertips, I’m reminded that it’s been two years since I first embarked on my journey with Microsoft. Joining during COVID meant that I did not get the onboarding experiences of a lot of Microsoft employees, a trip and onboarding in Redmond. Today, as I write this reflection, I’m filled with a mixture of nostalgia and pride over how much I, and the team I belong to, have grown-despite the miles that separate us.

Time to follow my Dream - I'm joining Microsoft!!!!

Scripting Winget

When I reset my PC or setup a new test machine, I always have to download a lot of software. In the past, I’ve used Chocolatey, Boxstarter, or just installed everything by hand. I’ve played with winget, as part of the Windows Insider program. It was first announced in 2020 but was highlighted during Build 2021. With the release of Windows 11, I’ve setup machines a few times and wanted to automate the process using the new winget command.

ARM - Part 1: Azure Resource Manager

The Journey Begins # I’ve been an azure developer for years. Originally I worked with “Classic Mode” and Cloud Services. Then I moved to ARM and Web Apps. Lately I’ve been doing DevOps but I only recently started working with ARM Termplates. First, let’s dive into a little history. History # Azure has grown and changed since it was first introduced. Originally, it was a research project called, “Project Red Dog”. Azure has been commercially available since 2010. For four years, there was a limited way to interact with Azure, ASM the Azure Service Manager.
