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 serving as core frameworks across hundreds of production
instances at Lynx Trading Technologies. Because no database on the market offered the
same combination of capabilities, these systems let Lynx open entirely new business areas —
advanced pre-trade risk management, locate routing (a marketplace for borrowed shares), pre-trade
compliance, and rapid entry into derivatives markets, the most technologically demanding sector in
finance — plus client-scale reporting that would otherwise be impossible to run profitably. Today
they power Lynx's most critical operations: real-time market-data ingestion, risk, monitoring,
order-routing analytics, and regulatory reporting. 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.
- Independently adopted in production beyond its origin at Lynx — Fortitudo Technologies
runs RayforceDB for time-series analytics, validating the system outside its sponsoring firm.

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 as a core framework for Lynx's most critical
operations — market-data ingestion, risk, monitoring, order-routing analytics, and regulatory reporting.

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.

Principal Systems Engineer & Architect of High-Performance Database Systems
2013 — Present
- Created ThePlatform (2016) — a columnar time-series database and the O programming language,
replacing Lynx's kdb+/q infrastructure for real-time market data, risk analytics, and order flow processing.
- Created RayforceDB (2020) — an original SIMD-first columnar database and the Rayfall language;
independently developed, then sponsored by Lynx for production adoption and continued development.
- Enabled entirely new lines of business impossible on existing databases — advanced pre-trade
risk management, locate routing (a marketplace for borrowed shares), pre-trade compliance, derivatives
trading, and client-scale regulatory reporting — across hundreds of production instances.
- Built low-latency trading infrastructure, market-data processing pipelines, and real-time analytics
systems for US equity markets.
