Building systems at the intersection of software, markets and security.
Founder, developer and investor building technical products across quantitative finance, cybersecurity, AI and infrastructure.

02Identity
A portfolio built for people who care what happens below the interface.
I build more than interfaces.
My work spans quantitative finance, cybersecurity, AI systems, developer infrastructure, distributed systems, and systems programming.
The common thread is not a framework. It is the discipline of turning complex relationships into software that can be used, inspected, and extended.

03The work
Eight systems. Different surfaces. The same insistence on understanding the whole machine.
Products with an architecture.
Hover a project. Select to open the system.
04Technology constellation
A stack is a set of trade-offs. Click a node to see where it carries weight.
LOW LEVEL PRODUCT SURFACEFOUNDATION ORCHESTRATION
One stack is never enough.
Different constraints ask for different tools. The interesting part is the seam between them.
05Domain constellation
The work crosses categories without losing its center.
Systems are defined by their context.
Finance and security ask different questions. Infrastructure and privacy impose different boundaries. The same engineering discipline has to survive all of them.

06Engineering philosophy
The principles behind the repositories.
Architecture before abstraction.
01Build complete systems.
02Understand the underlying technology.
03Prefer measurable engineering over hype.
04Ship, test, document, iterate.
07Open source
Open source is the portfolio.
Eight projects. Multiple languages. Multiple domains. The source is the proof.

08About
A short version is enough.
Useful beyond the demo.
I build software across finance, cybersecurity, AI and infrastructure, with a focus on systems that are useful beyond the demo.
09Contact
Build something difficult.
The best place to start is the work itself.
