Jess
Hi, I'm Jess

I build systems that cannot afford to fail.

My entry into software wasn't through a standard computer science pipeline; it was forged through discrete mathematics and military service. That background shaped how I approach engineering: structure first, absolute clarity on edge cases, and zero reliance on off-the-shelf abstractions when performance and data integrity are on the line.

I work primarily at the intersection of low-level systems, distributed reliability, and applied mathematics. Whether I am hand-writing zero-copy parsers in Rust, engineering network diagnostics in Go, or researching belief manifolds for AI memory architectures, my baseline requirement is the same: complete visibility into every layer of the execution stack.

I don't hide the learning curve or pretend to have all the answers upfront. I dive into complex, uncharted domain space, map the mathematical boundaries, build the solution from first principles, and own the results.

Production systems

01

GNN PDE CFD live

Built from scratch Graph Neural Network PDE solvers for computational fluid dynamics. With a validation dashboard that shows real output, including the fix for a spectral radius blow-up in autoregressive rollouts.

02

RheoLogos live

A double-entry payment ledger with an event-driven outbox, an idempotent consumer, and a dead-letter queue. Kafka and Redis run alongside the app, Postgres is managed.

03

FlagForge live

A real-time feature flag and configuration engine. Single binary, embedded UI, written in Go (I also have a Rust version) nothing else to run.

04

B2B Federation Gateway live

An enterprise identity gateway speaking SAML, OIDC, SCIM, and ABAC to each other, against a working demo tenant.

05

Micro Identity Sidecar live

A local-first OAuth 2.1 and OIDC authorization server, small enough to run as a sidecar next to whatever actually needs the auth.

06

NovaStructur live

A project manager that also tracks issues, not the other way around. Built to stay low bloat instead of turning into another Jira. It features a custom hand-rolled CRDT, an MCP for LLM integration, a tiny custom RAG with bespoke binary semantic search, and custom chunking logic specifically optimized for coding.

07

CollabPM live

A full blown collaborative project manager based on a Google Docs-style shared text editor over Action Cable with hand rolled custom CRDT, calendar and project intelligence MCP.

08

Archivum desktop

A local-first document vault. Desktop only, so this one gets a walkthrough video instead of a link once it's recorded.

RustTauri
09

Limes terminal tool, source linked

Diagnoses and fixes cross-cloud network conflicts: overlapping CIDR ranges, inconsistent private networking, DNS resolving differently across AWS, GCP, and Azure. Built alone, under production pressure, to fix a real outage. (It's not Limes like the fruit, it's Latin for frontier line or border defense).

GoCLI
10

Stemma building

Detects instructions embedded in content headed for an LLM or agent, and traces where they actually came from before anything acts on them.
