// about
We are a small firm, and we like it that way.
Gravexa, LLC is an engineering firm focused on backend services and app development. From the database to the App Store, we work with startups shipping their first product and with companies scaling systems that have served customers for a decade.
What sets the work apart isn't a methodology or a framework. It is the insistence on writing things down and shipping them. Every engagement leaves behind documents your team will keep reading, code your engineers can keep extending, and decisions whose tradeoffs are legible.
The backend is not a detail you bolt on at the end. It is the set of choices that determine whether your product survives real users and real load. We make those choices in your favor.

Founder & principal engineer
Thirty years building backend platforms and the products on top of them, from secure systems architecture to consumer apps. Companies and platforms that became foundational infrastructure for automotive, IoT, defense, and connected mobility.
Founded Valicore Technologies, whose secure device-lifecycle management platform was acquired by Green Hills Software and now operates as OmniTrust's security services business. From whiteboard to acquisition to scaled global deployment, that arc is the lens I bring to every engagement: solving the immediate technical problem and designing systems that grow, endure, and create lasting value.
Hands-on technical depth alongside strategic leadership. Architected globally deployed PKI and device-lifecycle systems, led engineering organizations of 30+ people, and delivered security infrastructure used by Fortune 50 companies. Currently the backend behind a consumer service platform used by more than 100,000 customers daily across North America, and growing worldwide.
If your company needs a partner who has founded, built, shipped, and scaled real systems, not just advised on them, let's talk.
