Software Engineer distributed & real-time systems
I design and build distributed, real-time systems, from a federated social platform to services that handle millions of transactions a day.
Co-founder & CTO
Co-founded a customizable federated social platform and led development end to end — native iOS/Android apps, a collaborative-filtering recommendation engine, RAG search on Pinecone, and a real-time Deck.gl + Go map streaming millions of points.
Senior Software Engineer
Built a batch system processing 10M+ transactions daily and a distributed cache that cut request latency by 60%. Led the migration of legacy monoliths to AWS Lambda microservices, and mentored junior engineers on Node.js and system design.
Senior Software Engineer
Built an ISP management platform — a custom WebGL renderer for 500K GeoJSON points, an ORM-style GraphQL query generator, and an RF line-of-sight elevation tool factoring terrain and Earth curvature.
M.A.C.H.I.N.A · Rust · Distributed Systems
A Rust-native engine that surfaces emergent trends before they reach mainstream volume — a partitioned actor runtime, HDBSCAN clustering, and momentum-weighted anomaly scoring, applied to social, security, and fraud data alike.
Atlas · Go · Real-Time Systems
The real-time backbone behind the Layers map — a Go service that holds a tenant's geospatial dataset in memory and streams it to browsers over a compressed MessagePack WebSocket, with an encode-once fan-out and a broadcast hub slow clients can't stall.
// Summary
I'm a software engineer focused on designing and building distributed, real-time systems and platforms. Over the last several years I've co-founded a company, shipped products to the App Store and Google Play, and built systems that move millions of transactions and data points a day.
My work spans the full stack — from WebGL data visualization and native mobile apps to distributed caching, GraphQL APIs, and Kubernetes infrastructure. Off the clock, I've volunteered in animal husbandry at the Texas State Aquarium and released sea turtle hatchlings on the Padre Island National Seashore.
