Execution infrastructure and AI-native operations.

Co-founder of SitiaFlow — a B2B ERP for hospitality with 215 use cases spanning front-of-house and back-of-house operations. The platform is multi-tenant, serverless, and exposes its domain through the Model Context Protocol so AI agents can read and write structured intents against the system.

Independently, I run research into proprietary trading infrastructure. A multi-engine Rust platform with cache-aligned indicator math, typed message streams, and pre-trade risk gates — built to be auditable before it ever touches real money. I take on a small number of advisory engagements focused on AI agent integration and MCP architecture. Based in Santiago, working globally.

Quantitative Trading Platform

A low-latency, multi-timeframe execution framework in Rust. Deterministic indicators, unidirectional data flow, and capital-preserving risk gates — built to be auditable before it ever touches real money.

  • Five decoupled engines (data ingest, market monitor, automation, portfolio, analytics) communicate through typed, versioned message streams.
  • Sub-millisecond indicator pipeline using cache-aligned SoA buffers; capital math pinned to 128-bit fixed-point decimals.
  • Pre-trade risk ladder (8 fail-closed gates) plus a Portfolio Veto that overrides execution when drawdown limits breach.

MixologyHub

High-concurrency inventory and point-of-sale platform with an MCP-native AI Bartender. Redis/BullMQ-backed ACID queues.

  • Serialized BullMQ queues with redis-backed ACID guarantees — concurrency: 1 on shared inventory.
  • AI Bartender via MCP tool calling, provider-agnostic, with ~90% token reduction through structured intents.
  • Adapter pattern normalizes TheCocktailDB and external APIs.
  • 190+ tests across Jest and Playwright; Dockerized microservices.

Trading Terminal

Algorithmic execution infrastructure for Bybit. FSM-driven DCA/grid strategies with sub-account risk isolation and hot-reload parameter configuration.

  • Deterministic finite-state machine per strategy — INIT → ACTIVE → EXIT.
  • Sub-account risk isolation: longs, shorts, and profit on segregated books.
  • TUI control surface with simple-term-menu; live config without downtime.
  • Clean architecture and adapter pattern over Bybit, Hyperliquid, and Bitget APIs.

Approach

  1. Deterministic before optimized. FSM, property tests, replay engines — outcomes must be reproducible before they are fast.

  2. Observable before automated. MCP, structured logs, event-driven — agents should never guess what the system did.

  3. Documented before deployed. ADRs, TDD, architecture specs — the next engineer inherits the why, not just the what.
