People person by nature, electrical engineer by training. I lead cross-functional technical teams, working directly with customers, to develop and implement innovative solutions.

I partner with small engineering firms to fuel their growth and position them for acquisition.

With 20+ years in technical and business leadership spanning DoD roles as a federal employee and private-sector small firms I bring proven expertise.  

Currently, as Chief Strategy Officer (CSO) at Mahlet, Inc., I’m leading the charge to redefine enterprise optical network cybersecurity with full-stack, Two-System Integrity (TSI) solutions for high-threat industries.  

Off the clock I'm a fitness enthusiast, personal finance geek, and real-estate investor...on the lighter side, I love socializing with friends, the Cleveland Browns, attending festivals, hitting local breweries, and chilling with a movie and a video game (at the same time🤯).

I've moved a ton throughout my life, but currently find myself with my family in the Washington, D.C. area enjoying all four seasons in moderation.

Hit me up – I love to network & chat!

Networking at 8am is hard! 


Thank goodness they had free coffee ☕

You can't tell from the photo, but I was still sleeping.

Really informative panels this morning on email business growth and exit strategy. 

So much to learn and do!!

Engineer | People person | CSO - Redefining security for enterprise optical networks so that the good guys can start winning again

Parents of teenagers:

When asked (dramatically) if you "have ANY food in the house" 

Use this guide.

Or at least refuse to feed them garbage so that they have to drive themselves to MacDonald's and spend their own money 🍻

Pretty sure the same goes for my LinkedIn cyber security rants 🤔

241 days and costs $10.22M - this was the average duration and cost of a network breach in 2025.


And it's not just about the time and money.

It's:
 - A hit piece in the NYT
 - Sleepless nights for security teams
 - Increased regulatory oversight & penalties
 - Your team tied up in lawsuits & congressional hearings instead of your jobs

The really scary part? 
Many of these breaches leverage the very systems you've installed to manage & protect your network.

 - Zero days
 - Backdoors
 - Insider threats
 - Unmonitored Layer 1 exploits & attacks

And you won't detect it or stop it until it's too late.
Because you can't find what you're not even looking for.

We can help you see the unseen.
DM me to learn how.

"Hot take, Jason, this budget is missing some key reinvestment objectives."

Leveraging my killer LinkedIn skills in the real world, I now start every sentence in my business meetings with, "Hot take."

So far, it's quadrupled our output and quintupled revenue.

The Cleveland Browns are undefeated in 2026!!

What a nice way to end another terrible season 🍻

Cybersecurity threats that were pointed out 30 years ago are still being ignored entirely today.

It was a layer 3, or the Internet Protocol (IP) layer, weakness back then.

It's a layer 1, or optical signal protocols (OTN, SDH, SONET) and Ethernet PCS, weakness now.

Covert communications channels in the 10s to 100s of Mbps that will bypass every security system in your network is just one terrifying example.

But it's not the only one.

Or the scariest.

Trusting your edge security devices to keep your network safe has become failing by default.

And it definitely ain't practicing "Zero-Trust"...

Instead, practice Two-System Integrity (TSI) across ALL protocol layers (OSI 1-7) to independently verify that these critical devices are behaving as expected, in real time, by looking directly at the data they're handling.
