Summary
Principal systems engineer and programming language creator with 18+ years of experience
building performance-critical infrastructure. Created two original database systems —
RayforceDB and ThePlatform — each with its own purpose-built programming language
(Rayfall and O), now in production at Lynx Trading Technologies powering
real-time analytics, order routing, and risk management across hundreds of instances.
These systems replaced incumbent kdb+ infrastructure, delivering 7-figure annual cost savings
while handling the same mission-critical financial workloads. Deep expertise in SIMD vectorization,
columnar storage design, language runtime implementation, and low-latency systems architecture.
Original Contributions
Original SIMD-first columnar analytical database (<1MB binary, zero dependencies) with
Rayfall
— an original Lisp-like array language for vectorized analytics. Created independently; subsequently
sponsored by Lynx Trading Technologies for production adoption.
- Designed and implemented a novel database architecture from scratch in pure C: SIMD-vectorized operators
(AVX2/NEON), cache-aware columnar layouts, mmap-based storage, and custom memory management.
- Created the Rayfall language: a composable, Lisp-like query language with first-class vectors, tables,
dictionaries, temporal types, and a comprehensive type system — offering an alternative paradigm to SQL
and kdb+'s q for analytical workloads.
- Built a complete ecosystem: core engine, Python bindings (DataFrame API), Rust bindings, WebAssembly
runtime, VS Code extension with REPL, benchmarking suite, and documentation.
- Adopted by Lynx Trading for production financial analytics — Lynx sponsored continued development
based on the system's performance advantages over incumbent solutions.

Columnar time-series database and real-time analytics stack created for
Lynx Trading Technologies,
featuring the original
O programming language
— a vector language inspired by APL/k with first-class tables, async reagents, and join-calculus concurrency.
- Designed and implemented a complete database system with its own programming language, replacing
Lynx's kdb+/q infrastructure for real-time market data, risk analytics, and order flow processing.
- Created the O language: vector-oriented with nanosecond timestamps, streaming pub/sub, pattern matching,
and declarative concurrency — purpose-built for financial time-series workloads.
- Built async communication reagents (TCP/UDP/WebSocket/IPC/TLS), plugin architecture, and standard
library enabling Lynx to consolidate multiple vendor tools into one platform.
- Deployed across hundreds of production instances at Lynx, contributing to 7-figure annual savings
by eliminating kdb+ license costs and reducing operational complexity.

TeideDB — Creator & Lead Architect
2024 — Present · teidedb.com
Analytical SQL engine / embedded analytics runtime extending the Rayforce ecosystem with a modern
SQL interface over a vectorized, in-process execution model.
- Vectorized operators and optimizer-oriented architecture for fast analytical workloads.
- Designed for agent-driven analytics pipelines and interactive reporting over columnar data.

Open-source knowledge infrastructure built on the Teide columnar engine — syncs work tools,
indexes content, and serves data to AI agents via MCP and applications via REST.
- BM25-ranked full-text search, SQL analytics, graph traversal; dual API (MCP + REST).
- Single Rust binary, zero cloud dependencies, incremental sync from Notion/Zulip/databases.
